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:
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:
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.
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.
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:
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.
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.

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.

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.

Faculty — Jeffrey Boris, MD, Julie Brothers, MD, Aaron Dorfman, MD, Stanford Ewing, MD, Christine Falkensammer, MD, Paul Farrell, MD, Matthew Harris, MD, Alexa Hogarty, MD, Katharine Levinson, MD, Paul Stephens, MD, Kevin 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.

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.
Medical Director — Stephen Paridon, MD
Faculty — Julie Brothers, MD, Alexa Hogarty, MD, Michael McBride, PhD, Paul Stephens, 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:
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:
Medical Director — Brian Hanna, MD, PhD
Faculty — Alexander Davidson, MD, David Frank, MD, PhD, Therese Giglia, MD, Rachel Hopper, 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.
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).
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.
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.
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.
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:
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.

Fellows are encouraged to attend annual professional meetings in order to meet and learn from expert faculty in the field and to network with alumni and peers:
To be eligible to apply for the Fellowship in Pediatric Cardiology, physicians:
All applications for standard three (3)-year categorical fellowships must be electronically through the Electronic Residency Application Service (ERAS), the online application service of the American Association of Medical Colleges (AAMC). The annual official deadline for a completed application is December 1. Although applications are considered on a rolling basis as they are completed, applicants who meet the deadline ensure consideration in the first round review by our fellowship selection committee. If selected to interview, requests for specific interview dates are more easily accommodated for applicants who are invited earlier in the season.
The following documents must be received by ERAS prior to consideration of your application:
Our program participates in the National Residency Matching Program (NRMP) Pediatric Subspecialties Spring Match. Anticipated application and recruitment timeline (and notable deadlines) for the upcoming season are as follows (these dates are approximate and based on previous years):
Military (ROTC)-funded applicants and occasional non-traditional applicants may be program-eligible on a case-by-case basis. For consideration, please contact Meryl S. Cohen, MD, program director.
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 electronic or regular mail to:
