Stachelek, Stanley

Dr. Stachelek's research has been concerned with biocompatibility mechanisms and devising therapeutic solutions to polymeric biomaterials. In particular, his work examines the cellular and molecular response to CD47 modified surfaces such as those used as blood conduits for cardiovascular devices. He has published on the novel mechanistic roles that CD47 plays in mediating inflammatory cell interactions with polymeric biomaterials and cardiovascular devices which were the first to characterize the platelet response to CD47 modified surfaces. The overall goal is to characterize the anti-inflammatory properties of CD47 functionalized polyurethane and understanding the CD47 associated signaling mechanisms that mediate inflammatory cell activation.

Program overview

The pediatric cardiology fellowship at Children’s Hospital of Philadelphia is one of the nation’s oldest, largest and most well-established pediatric subspecialty training programs, with continuous ACGME accreditation since May 8, 1965.

The goals of the program are:

  • To produce well-rounded pediatric cardiologists who are competent clinicians in all subspecialty areas of practice
  • To develop physician scientists whose published research and investigative activity will make significant contributions to the advancement of knowledge in the field
  • To create innovators and leaders in academic medicine whose teaching and administrative skills will be an asset to the institutions they serve 

The mission of the program is to prepare trainees for careers in academic pediatric cardiology. We accomplish this through a three (3)-year program that balances extensive clinical exposure to a broad spectrum of congenital and acquired heart defects and cardiac arrhythmias with time spent in active clinical or basic research. Fellows accept progressively more responsibility in each year of the training program. Fellows are encouraged to complete a fourth year of training in order to extend their research experience or develop specialized clinical expertise in areas such as interventional catheterization, electrophysiology, non-invasive imaging, cardiac intensive care, heart failure/transplant and pulmonary hypertension.

Fellows’ clinical and academic progress is monitored via monthly rotation evaluations as well as a semi-annual review process supervised by our Clinical Competency Committee (CCC), which measures Fellows’ professional growth and achievement of pediatric subspecialty training milestones in accordance with the following six (6) ACGME-defined core competency areas:

  • Patient care
  • Medical knowledge
  • Practice-based learning
  • Professionalism
  • Interpersonal skills and communication
  • Systems-based practice

While the outcomes-based core curriculum is intentionally highly structured and rigorous, Fellows take an active role in shaping their own education through formal program evaluation and class representative participation on the Program Evaluation Committee (PEC). Fellows are also given the opportunity to provide informal feedback to the program director during Fellows’ meetings and to other teaching faculty, including medical directors, when they are on service or available to meet. Changes to the program or its stated goals are amply discussed and reviewed prior to implementation.

To further enhance our trainees’ opportunities for success and assist them with both navigating the transition from general to subspecialty practice and meeting their professional goals and academic requirements, each trainee is paired with a personal faculty mentor and a research faculty mentor. Mentors are selected for each mentee based on “model” career paths, goals and fields of interest. Additionally, program leadership is always available on an ad hoc basis for resources and support.

Training sequence

Year one

The first year of the program is 90 percent clinical in focus, with an emphasis on training fellows in the care of cardiac patients in the inpatient setting as well as in the use of various imaging modalities and other laboratory studies in the pediatric cardiologist’s repertoire.

Fellows will spend two months on the inpatient (CCU) service gaining exposure to a variety of congenital and acquired heart defects including rheumatic fever, Kawasaki disease, collagen vascular disease, bacterial endocarditis, and pre- and post-operative cardiac transplantation cases. Fellows will spend two months in the noninvasive imaging laboratories and two months in the cardiac catheterization laboratories, developing an understanding of major diagnostic tools and approaches to treatment.

Two (2) months in the cardiac intensive care unit (CICU) provide first-year fellows experience with critically ill patients of all ages, particularly those undergoing various forms and stages of heart surgery and palliation. Fellows assigned to the CICU will obtain and provide consultations with a diverse team of front line caregivers — cardiothoracic surgeons, cardiac anesthesiologists, critical care physicians, neurologists, geneticists, nutritionists and a highly specialized nursing team — to optimize patient-and-family-centered care.

Finally, in the first year of training, the program features a unique one (1)-month experience in cardiac pathology based on the morphologic method and segmental approach to the diagnosis of congenital heart disease. The outcomes-based curriculum provides trainees with a detailed knowledge of three-dimensional cardiac anatomy so that they will be able to utilize imaging tools, interpret studies and communicate precise diagnostic information effectively with colleagues and patients/families in their care.

Year two

The second year of fellowship incorporates additional time on the non-invasive and catheterization services (approximately one (1) month of each) with at least two (2) weeks’ exposure to the following subspecialty areas:

  • Adult congenital heart disease
  • Cardiac magnetic resonance imaging
  • Exercise physiology
  • Heart failure/transplant
  • Pulmonary hypertension

These experiences help the fellow consider particular clinical interests and strengths and explore possibilities for advanced training.

In addition, as the second year fellow now has a foundation in the basics of clinical cardiology, five to six  total months of research time will be set aside for research. Fellows working in a basic science laboratory may arrange their schedule for more contiguous blocks; fellows doing clinical research may opt to interrupt or alternate research blocks with some clinical rotations.

Year three

In the third year of fellowship, trainees will complete the formal research block (and the required scholarly work product for professional board exam eligibility) and resume clinical work in the CICU and various cardiology clinical laboratories. They will participate in the consult service, and in some cases, will participate on the CCU in a “pretending” role.

“Senior” fellows are expected to assume a greater degree of responsibility on these rotations, often taking on certain teaching responsibilities to junior fellows and residents that are commensurate with their experience, as determined and supervised by attending faculty. 

Note: Many fellows opt to do additional “Consult” time in the second or third year, to continue skills-based learning in the inpatient setting that will enhance and further their progress toward the goal of becoming independent practitioners.

This rotation provides the opportunity to work closely in tandem with the cardiology attending to handle internal and external emergency department referrals, requests from other pediatric subspecialty inpatient units, and efficient management and use of hospital imaging and testing laboratory resources. The fellows’ skills in interpersonal communication, professionalism and systems-based practice are highlighted such that the service attendings can provide valuable, often real-time feedback regarding a fellow’s knowledge base and readiness for practice.

With a similar focus in mind, fellows are responsible for attending their weekly half-day continuity clinics throughout their three years of training with the exception of blocks of CCU, CICU, night float and vacation. In this manner, fellows learn effective time management from balancing patient care responsibilities with other aspects of their academic and clinical workload.


Adult congenital heart disease (ACHD)

Medical Director — Yuli Kim, MD

Faculty — Sara Partington, MD, Emily Ruckdeschel, MD

The Philadelphia Adult Congenital Heart Center is a joint venture between CHOP and the Hospital of the University of Pennsylvania. During the ACHD rotation, the fellow will gain the knowledge, skills and attitudes necessary to provide appropriate, effective and compassionate care to adults with congenital heart disease. Fellows are required to learn and review methods for taking an adult cardiac history and physical examination, and to competently make informed diagnostic and therapeutic decisions based on patient information, current scientific evidence and clinical judgment.

Under the supervision of the ACHD attending faculty, the fellow will outline management and treatment plans that incorporate understanding of the problems commonly seen in adults with congenital heart disease.

Fellows are expected to demonstrate knowledge of the natural and unnatural history of congenital heart disease and the established and evolving biomedical, clinical, epidemiological and social-behavioral science related to this population. They should be able to provide effective counseling with regard to medical issues such as pregnancy and contraception. Fellows should be aware of the unique psychosocial needs that must be met for these patients in transitioning from pediatric to adult care, and participate in care coordination that reflects understanding of the capacity and limitations of the healthcare system relevant to their clinical specialty.

Cardiac care unit (CCU)

Medical Director — Susan Schachtner, MD

Faculty — Meryl Cohen, MD, Therese Giglia, MD, David Goldberg, MD, Katharine Levinson, MD, Shobha Natarajan, MD, Matthew O’Connor, MD, Chitra Ravishankar, MD, Anita Szwast, MD

The Cardiac Care Unit (CCU) rotation is designed for the fellow to develop expertise in the acute and chronic medical management of infants and children diagnosed with congenital and acquired heart disease. While on this rotation, fellows will learn how to interpret various imaging and other laboratory modalities for diagnosis and management, and when to refer patients for cardiac surgery.

Fellows participate in daily morning rounds with the pediatric residents and cardiology attending, reviewing physical findings, laboratory results and management plans for each patient. The fellow supervises the management of medical inpatients on the service (admissions and discharges), and teaches basic cardiology topics and focused histories to the residents.

Fellows spend two separate months in the CCU at different stages in the first year so they can build on the understanding acquired in their first rotation with additional skills and knowledge gleaned from other subspecialties later in the year. Service coverage rotates weekly; fellows may work with three to five different supervising faculty in a given four-week period, which provides ample opportunity for learning, mentoring, clinical skills development and feedback.

Cardiac intensive care unit (CICU)

Medical Director — Andrew Costarino, MD

Faculty — Joshua Blinder, MD, Marissa Brunetti, MD, Jodi Chen, MD, Aaron DeWitt, MD, Maryam Naim, MD, Stacie Peddy, MD, Joseph Rossano, MD

Critically ill medical and surgical patients with cardiovascular disease are cared for in the Cardiac Intensive Care Unit (CICU) by a dedicated team of cardiologists and critical care specialists including cardiothoracic surgeons. During this rotation fellows become familiar with all aspects of care for critically ill cardiac patients including:

  • Airway management and mechanical ventilation
  • Preoperative stabilization
  • Cardiopulmonary bypass and its sequelae
  • Technical aspects of cardiac surgery and postoperative management

Cardiology fellows work closely with critical care, cardiac anesthesia and cardiac surgery fellows in the management of all patients in the CICU, including pre- and post-operative care and participation in invasive procedures. Responsibilities include:

  • Participation in morning and evening rounds with the CICU team
  • Participation in night call coverage
  • Preparation of weekly pre-surgical conference and monthly CICU mortality and morbidity conference
  • Coordination of all appropriate pre- and post-operative testing (e.g. electrocardiograms, 24-hour ambulatory monitoring, echocardiograms and cardiac catheterization

Consult service

Medical Director —Joshua Blinder, MD

Faculty — Julie Brothers, MD, Aaron Dorfman, MD, Stanford Ewing, MD, Christine Falkensammer, MD, Paul Farrell, MD, Matthew Harris, MD, Alexa Hogarty, MD, Katharine Levinson, MDPaul Stephens, MDKevin Whitehead, MD

The goal of the consult service rotation, undertaken in the fellow’s second and/or third year, is to ensure that the fellow fully develops the knowledge, skills and attitudes required to provide cardiology consultation service in the evaluation and treatment of infants, children, adolescents and adults with acquired and congenital cardiac disease.

The tasks of appropriately utilizing information technology to optimize patient care, providing sensitive counseling to families, and collaborating with other members of the allied health team to refer patients from other units and specialty disciplines for further cardiac screening create a focus on practice-based learning.

The fellow is challenged to perform honest self-assessment of strengths and limitations that will foster professional growth and further expand competency and understanding of systems-based practice. Viewed appropriately in its larger context, the consult service is a formative benchmark of the fellow’s maturity, fund of knowledge, and readiness to become an independent practitioner.


Medical Director — Maully Shah, MD

Faculty — Christopher Janson, MD, Victoria Vetter, MD

Approximately 200 procedures are performed annually in the Cardiac Electrophysiology Laboratory. Fellows rotate through this lab twice during their second or third year, learning how to use electrophysiologic information and technology to diagnose and treat various types of cardiac arrhythmia. Fellows gain experience with:

  • Electrocardiographic interpretation of complex arrhythmias on standard electrocardiograms
  • 24-hour ambulatory (Holter) monitors
  • Transtelephonic monitors
  • Acute and chronic management of arrhythmia patients

Trainees participate in daily arrhythmia rounds, all outpatient arrhythmia visits, pacemaker clinic, EP consult service, intracardiac electrophysiology studies and operative and catheter ablation procedures.

Interventional cardiology (cardiac catheterization)

Medical Director — Jonathan Rome, MD

Faculty — Yoav Dori, MD, Matthew Gillespie, MD, Andrew Glatz, MD

Approximately 1,200 diagnostic and therapeutic procedures are performed each year in the Cardiac Catheterization Laboratory. Beginning in the first year of fellowship, trainees are assigned to catheterization laboratory procedures under the guidance of a staff physician. With each successive rotation through the lab, fellows assume more responsibility for performing procedures. At any given time, one or more attendings are available if help is needed or a complication develops. A comprehensive team including cardiac anesthesiologists and CT surgeons may lend assistance in cases of emergency.

Fellows participate in daily pre-catheterization conferences, present and discuss data at weekly post-catheterization conferences, and attend weekly angiogram review sessions. Fellows participate in approximately 150 catheterization procedures during their training.

By completion of fellowship, trainees are able to plan, perform and interpret a complete diagnostic study. For those with special interest in invasive cardiology, there is opportunity to develop skills in therapeutic catheterization during the latter portion of fellowship training.

Non-invasive imaging


Medical Director — Michael Quartermain, MD

Faculty — Anirban Banerjee, MDMeryl S. Cohen, MDKarl Degenhardt, MD, PhDAaron Dorfman, MDStanford Ewing, MD, Christine Falkensammer, MD, Mark Fogel, MD,Marie Gleason, MD, David Goldberg, MD, Betsy Goldmuntz, MDAlexa Hogarty, MDMatthew Jolley, MDLaura Mercer-Rosa, MD, Sumekala Nadaraj, MD, Shobha Natarajan, MDMatthew O’Connor, MDJack Rychik, MDMohamed Seliem, MDPaul Stephens, MD, Anita Szwast, MD

During the echocardiography laboratory rotation, fellows acquire the knowledge and skills necessary to correctly perform and interpret transthoracic (TTE), transesophageal (TEE) and fetal echocardiograms. Fellows will participate in a minimum of 300 TTE studies and approximately 100 to 125 (total) TEE and fetal studies on patients ranging in age from neonates to adults.

Fellows will learn to differentiate various technical modalities including M-mode, 2D, Doppler and color flow imaging, conduct proper probe selection, and to correctly identify and describe the function of the echo machine knobs. They will be able to identify the indications for various types of studies and work collaboratively with laboratory staff to build efficiency, improve communications, create quality improvement initiatives and enhance procedural and process workflow.

A weekly didactic echocardiography laboratory conference and daily teaching sessions conducted by faculty and the senior noninvasive imaging fellow(s) provide multiple opportunities for trainees to develop and enhance their technical skills and fund of knowledge. Advanced imaging modalities are also introduced including 3D imaging and deformation imaging.

If the fellows’ proficiency and interest indicate and available funding for additional training can be secured, a fourth year of training is strongly encouraged.

Exercise physiology

Medical Director — Stephen Paridon, MD

Faculty — Julie Brothers, MD, Alexa Hogarty, MD, Michael McBride, PhD, Paul Stephens, MD

Fellows will learn to competently monitor patients and collect, record and interpret data from exercise studies during their rotation in the Exercise Lab. At completion of the rotation, the fellow should be able to describe the conduct and protocols of a regular exercise and pharmacologic stress test, describe the equipment used, and develop a preliminary or independent interpretation of the study data depending upon the year of training (second and third year, respectively).

Fellows should know basic exercise physiology as it relates to the cardiovascular, pulmonary and musculoskeletal systems, and know the indications and contraindications for exercise testing.

Magnetic resonance imaging

Medical DirectorMark A. Fogel, MD

Faculty — Matthew A. Harris, MD, Marc Keller, MD, Sara Partington, MD, Kevin Whitehead, MD
Special Consultant – Paul M. Weinberg, MD

In the Cardiomagnetic Resonance Imaging Laboratory, fellows are required to observe at least 40 percent of the MRI studies conducted during the rotation. Fellows will:

  • Learn to compare and contrast different types of MRIs (e.g. spin echo, cine, magnetic tagging) and be able to list the advantages and limitations of cardiac magnetic resonance as a diagnostic modality.
  • Be able to correctly identify cardiac anatomy, interpret cardiac physiology and correctly synthesize diagnoses obtained from magnetic resonance studies. The fellow will be able to concisely and accurately convey pertinent data obtained from MRI at surgical conference.

Heart failure/transplant

Medical Director — Matthew O’Connor, MD

Faculty — Kimberly Lin, MD, Joseph Rossano, MD

The goal of the Cardiomyopathy/Heart Failure/Transplant rotation is that at the end of the fellowship, the fellow has the required knowledge, skills and attitudes to effectively evaluate and initiate management of infants, children and adolescents with cardiomyopathy and heart failure, and patients who have undergone cardiac transplantation. The fellow will:

  • Learn to competently obtain a complete history and physical examination for all subgroups within this population and to develop an initial management plan for heart failure and cardiac allograft rejection.
  • Participate in new inpatient consults, transplant evaluations, consult follow-ups and inpatient rounds with a focus on compassionate, ethical care of patients, and sensitive, informed communication with families, including counseling regarding non-medical interventions and hospital and community services.
  • Enhance his or her fund of knowledge by studying the natural history of cardiomyopathy, the role of genetic testing in cardiomyopathy evaluation, the pathology and pathophysiology of heart failure, post-transplant cardiac physiology, acute and chronic rejection, basic transplant immunology, and medications and interventions for patients with heart failure and post-transplant patients. Attend weekly multi-disciplinary Transplant Rounds, daily morning huddles in the Cardiac Intensive Care Unit and transplant surgical conference in addition to other didactic lectures and rounds in order to enhance understanding of patient advocacy and optimization of care.

Outpatient clinic

Medical Director — Marie Gleason, MD

Faculty — Anirban Banerjee, MD, Meryl Cohen, MD, David J. Goldberg, MD, Paul Farrell, MD, Shobha Natarajan, MD, Stephen Paridon, MD, Susan Schachtner, MD, Paul Stephens, MD, Anita Szwast, MD

Each of our 18 categorical first- through third-year fellows is assigned to a half-day Fellows’ outpatient clinic held on a Tuesday, Wednesday or Thursday.  These clinics are staffed by two (2) attendings.  Each clinic has fellows from all years, and clinic assignments are distributed evenly by class year so that fellows may learn from and collaborate with peers as well as senior faculty and ancillary members of the healthcare team. The rationale is to create a “continuity of care” model wherein the fellow can see a wide range of patient referrals.

We encourage fellows to follow patients with acquired and congenital heart disease throughout their course of treatment — from inpatient unit, emergency department or primary caregiver referral to diagnosis and subsequent medical and/or surgical intervention and post-operative care.

Fellows will learn to perform a thorough cardiac-focused history and physical examination. They will learn to make informed diagnostic and therapeutic decisions, professionally counsel patients and families with cultural competence, awareness and sensitivity, and use information technology competently and efficiently to optimize patient care. Fellows must:

  • Demonstrate the ability to investigate and evaluate the care of their patients.
  • Locate, appraise and assimilate information from scientific studies.
  • Incorporate formative evaluation feedback into their daily practice.
  • Conduct constant self-evaluation regarding strengths, deficiencies and limits in their knowledge and expertise.
  • Demonstrate a growing understanding of the larger context and system of healthcare and an ability to call effectively on other resources in the best interest of the patient.


Medical Director — Paul Weinberg, MD

Faculty — Meryl Cohen, MD

The ability of the cardiologist to provide precise anatomic diagnosis is essential to effective treatment including surgical intervention for the most complex congenital defects. During the one-month cardiac pathology rotation unique to our training program, the fellow will:

  • Learn the segmental approach to cardiac diagnosis and the morphologic method of cardiac description and become acquainted with a wide variety of congenital heart defects.
  • Learn the correlation of imaging (echocardiography, angiography, MRI) with a detailed knowledge of three-dimensional pathologic anatomy such that he or she will be able to use and teach others to use these powerful imaging tools effectively in the clinical setting.
  • Perform a detailed examination of at least 30 postmortem specimens in the cardiac registry and review during independent study sessions with the director.
  • Do a research project and case presentation and attend a weekly dissection conference and pathology conference in addition to all cardiac autopsies.

Pulmonary hypertension

Faculty — Catherine Avitable, MDAlexander Davidson, MD, David Frank, MD, PhD, Therese Giglia, MD

The Pulmonary Hypertension (PH) Program provides care to children with a wide variety of diagnoses that involve pulmonary vascular pathophysiology. The service averages approximately 20 inpatients on PH-specific therapies daily.

Fellows participating in the care of our patients have the opportunity to learn about the physiology of the failing cardiovascular and pulmonary vascular systems, hemodynamic evaluation, and medical management particular to the care of patients with end-stage heart and/or lung disease. This includes those children with idiopathic PH, congenital heart disease with associated pulmonary vascular disease, cardiomyopathy with severe restrictive physiology, “inoperable” pulmonary vein stenosis/occlusion and right heart failure from PH associated with chronic lung disease.

Fellows are involved in decisions around the evaluation and treatment of pulmonary hypertension with oral, intravenous and subcutaneous therapies and are welcomed in pulmonary hypertension clinic. This collaborative and comprehensive program involves the Divisions of Cardiology, Cardiothoracic Surgery, Cardiac Anesthesiology, Cardiac Critical Care Medicine and Pulmonary Medicine.

Fellows are encouraged to participate in and initiate research projects. The section is active in over two dozen hospital-based, multi-divisional and/or multi-centered research studies, and there is ample opportunity to present at national meetings and author manuscripts. A fourth year fellowship in pulmonary hypertension including advanced clinical and research objectives is offered.

Research opportunities and goals

Research overview

In an increasingly competitive professional job market, the well-trained pediatric cardiologist should have solid bench research and academic investigative skills in addition to comprehensive clinical knowledge and expertise. The specialist should have detailed knowledge of industry standards for experimental design, data collection and analysis and laboratory techniques.

Our fellowship program’s research curriculum has a clearly outlined sequence of goals and objectives to ensure that each fellow meets the minimum requirements for scholarly activity and a scholarly work product per the American Board of Pediatrics criteria, but may also consider and incorporate graduate and post-graduate scholarship and funding opportunities for advanced specialization as part of training at CHOP (See research activity timeline). 

Research timeline

Fellows are encouraged to begin thinking prospectively about their research work in cardiology as early as the fellowship interview/program selection. Fellows can follow up on this brainstorming process when they meet with a clinical faculty mentor early in the first year.

First year

Fellows will receive a review of the research curriculum and expectations in the fall of their first year and work with their clinical faculty mentor to identify a research faculty mentor by the end of the first year.

Second year

In the second year, fellows work with the research director and coordinator (with input from their clinical mentor and research mentor) to form a Scholarship Oversight Committee (SOC) consisting of the following members:

The entire committee will meet with the fellow and research mentor two to three times in the second and third year of training to ensure project feasibility, timeliness and efforts toward completion. The SOC will review the fellow’s individual development plan, proposed project summary (aka “white paper”) and IRB submission protocols.

In addition to meeting with the SOC, fellows have an opportunity at least once per year in the second and third year to present research to division faculty and peers at Fellows’ Research Conference. Fellows are encouraged to submit posters and abstracts to major conferences such as the American College of Cardiology Scientific Sessions and CHOP’s own annual Cardiology Update.

Third year

The third and final year of training includes five to six months of largely uninterrupted research time, focused on project completion. Examples of scholarly activity work products per the American Board of Pediatrics may include:

  • A first author or co-authored paper published in a peer-reviewed journal
  • An in-depth manuscript describing a completed project
  • A thesis or dissertation written in connection with pursuit of an advanced degree
  • An extramural grant application that has been accepted or favorably reviewed
  • A progress report for a project of exceptional complexity (e.g. a multi-year or multi-facility clinical trial)

Additional opportunities

In the fall of the second year, depending on personal academic and career goals, the fellow may wish to consider applying for the Master of Science in Clinical Epidemiology (MSCE) or Master of Science in Translational Research programs offered by the University of Pennsylvania and/or the Division-sponsored NIH T32 funding grant.

Applying for the T32 and other external funding sources is particularly encouraged for those trainees who wish to secure advanced clinical training (PGY-7 and PGY-8) positions. In the first year, fellows interested in these opportunities should arrange a meeting with the research director in the late fall and also collaborate with peers in the late spring to arrange their future block schedule so that clinical rotation requirements are completed as early as possible, in compliance with academic demands and grant protocols.


Fellows are required to attend an average of six (6) to eight (8) hours of didactic or lecture-based instruction per week that will enhance their clinical practice and fund of knowledge. Unless otherwise indicated, sessions are open to faculty and other members of the allied health professions from across disciplines and institutions.

Senior/advanced fellowships

Fourth and fifth year fellowships (PGY-7 and PGY-8) are offered contingent on funding and availability.

In recent years, the noninvasive imaging (echo and MRI), interventional cardiology, electrophysiology and cardiac critical care practice groups have recruited trainees on a regular basis. There are also opportunities to pursue advanced training in adult congenital heart disease, heart failure/transplant, cardiac pathology, pulmonary hypertension, exercise physiology and research.

Training eligibility varies by subspecialty, though most applicants commonly will have completed a three-year fellowship in pediatric cardiology and/or pediatric critical care medicine. It is recommended that prospective advanced trainees contact the section director(s) with specific questions and concerns.

Application materials for advanced subspecialty fellowships are sent directly to the program, not through ERAS. Once completed, these files are sent to the director(s) for review. A completed fourth- and fifth-year training application will include:

Please send these materials directly via email to or regular mail to:
