Innovative Learning Environment

The mission of the Pediatric Cardiology Fellowship is to train the next generation of leaders in pediatric cardiology within an innovative, collaborative and trainee-focused environment. This fellowship is a three-year program that includes robust education and training in all facets of pediatric cardiology needed to develop as an outstanding general pediatric cardiologist.

The Johns Hopkins All Children’s Heart Institute provides comprehensive care to children and adults with congenital heart disease. Fellows will be involved in all aspects of the spectrum of care including multiple echocardiography and non-invasive imaging modalities, cardiac catheterization, electrophysiology, cardiovascular surgery, adult congenital heart disease (ACHD), and the cardiac transplantation program as well as our cardiomyopathy and cardio genetics programs. Fellows play an integral role in a busy cardiovascular intensive care unit. Our pediatric referral center has expertise in emergency medicine, expanded subspecialty surgical and medical services and advanced pediatric transport with admissions from the greater Tampa Bay area, Southwest Florida and Central Florida.

The cardiology team treats children with heart conditions ranging from common to complex, and includes specialized programs such as advanced cardiac imaging, cardiac high-risk monitoring for patients with conditions such as single-ventricle heart defects, a cardio-genetics clinic, specialized cardiomyopathy treatment (recognized as a Center of Care by the Children’s Cardiomyopathy Foundation), electrophysiology, interventional cardiology and pulmonary hypertension.

Research and Investigation

The Johns Hopkins All Children’s Pediatric Cardiology Fellowship provides robust training in all aspects of clinical pediatric cardiology in addition to foundational scholarly education leading to an in-depth understanding of biostatistics, clinical and laboratory research methodology, preparation of applications for funding, and critical literature review as well as ethics and principles of evidence-based medicine. Proficiency in teaching will also be achieved.

In addition to the core curriculum, fellows will participate in projects where they develop hypotheses and conduct scholarly exploration and analysis of critical issues in pediatric cardiology. Areas of scholarly activity may include, but are not limited to: basic, clinical or translational biomedicine, health services, quality improvement, bioethics, education and public policy.
