Kathryn L. Maschhoff, MD, PhD, is an attending neonatologist in the Division of Neonatology at Children's Hospital of Philadelphia with a special interest in cardiac development and conotruncal heart defects.
I am a neonatologist interested in cardiac development, particularly in the development of the conotruncal region of the heart. Neural crest cells, which migrate to the developing heart from the neural tube, are essential for normal conotruncal development. Disruption of the normal migration or function of these cells in animal models recapitulates many of the features of DiGeorge syndrome seen in humans, including conotruncal cardiac defects such as persistent truncus arteriosus and interrupted aortic arch.
One focus of my research program is to understand how neural crest cells interact with other cells in the developing outflow tract during conotruncal development. A second focus of my research program is to elucidate the role of members of the Sox family of transcription factors, particularly Sox4 and the closely related transcription factor Sox11, in cardiac development. I have recently cloned the Sox4 gene and am using a variety of techniques, including in situ hybridization and expression of sense, antisense and dominant negative Sox gene transcripts by adeno- and retroviruses to study the function of Sox4 and Sox11 during cardiac development.

Patient Experience Ratings
About the Patient Experience Rating System
The Patient Experience Rating is an average of all responses to the care provider related questions shown above from our nationally-recognized Press Ganey Patient Satisfaction Survey. Patients that are treated in outpatient or hospital environments may receive different surveys, and the volume of responses will vary by question.
Responses are measured on a scale of 1 to 5 with 5 being the best score.
We are committed to true transparency. However, to ensure the comments are fair and correctly attributed, we review each one before posting to the website. We exclude entire comments that disclose patient's protected health information, are off-topic, or include other confidential or inappropriate content. Comments will appear on provider bios only if providers have a minimum number of comments.
Comments are shared internally for education purposes to ensure that we are doing our very best for the patients and families for whom we are privileged to care.
The comments are submitted by patients and families and reflect their views and opinions. The comments are not endorsed by and do not reflect the views of Children’s Hospital of Philadelphia.
