Pediatric Cardiology Fellowship

Message from the program leadership

Welcome to the OHSU Pediatric Cardiology Fellowship Training Program! OHSU has offered training in pediatric cardiology for well over 25 years. We are the only pediatric cardiology fellowship program in Oregon and one of two programs in the gorgeous Pacific Northwest.

We are committed to providing a rigorous and challenging training experience while nurturing personal wellbeing. Our fellows graduate with a solid and comprehensive foundation of knowledge and clinical experience, as well as a record of scholarship and teaching which position them well for the next steps in their career.

Part of our commitment to our fellows is to help them achieve their ideal position following graduation. Graduates of our program typically pursue advanced training and remain in academic positions. Our fellows have been offered advanced training opportunities at Stanford, Boston Children’s Hospital, UCSF, UCSD, Colorado Children’s Hospital, NYU, and other outstanding programs throughout the US and Canada.

We are a mid-sized surgical program, performing over 200 cardiac surgeries and over 300 cardiac catheterizations per year. Our 19 faculty members provide sub-specialty expertise in interventional cardiology, electrophysiology, echocardiography, fetal cardiology, cMRI and CT, pulmonary hypertension, aortopathy, cardiogenetics, neurodevelopmental outcomes, single ventricle disorders, exercise physiology, cardiac rehabilitation, dyslipidemia, and others. Our program is closely integrated with the adult congenital heart disease program at OHSU.

Our two congenital cardiothoracic surgeons, Dr. Irving Shen and Dr. Ashok Muralidaran, together with two advanced practice providers, perform all congenital cardiac surgical procedures with the exception of heart transplantation for which we closely collaborate with internationally recognized pediatric heart transplant centers.  The surgical team are closely involved in all aspects of peri-operative care and fellow education.

Our fellows primarily work at a single facility. Doernbecher Children’s Hospital is a free-standing academic children’s hospital providing the widest range of pediatric services in Oregon. The echo lab, operating room, pediatric ICU, wards, and continuity clinic are all located within Doernbecher. Additional training environments, including the catheterization lab, cardiac MRI/CT, cardiopulmonary exercise studies, obstetrics units, NICU, emergency department and adult congenital services are located in the OHSU Hospital which is connected to Doernbecher Children’s Hospital via a bridge.

We take immense pleasure and pride in training fellows in pediatric cardiology. If you have any questions, please don’t hesitate to contact us.

  • To develop outstanding clinical pediatric cardiologists 

  • To provide a rigorous scholarly experience preparing graduates for a fulfilling academic career 

  • To train future leaders in Pediatric Cardiology 

  • To capitalize on unique aspects of OHSU in order to enrich the training experience and teach unique skills that may not be offered at other programs 

  • To provide a rigorous training experience while nurturing personal well being

Fellows receive four weeks of vacation per year.  

Funds are available for fellows through grant opportunities or in discussion with the fellowship program director to support expenses to present their research at a regional or a national conference. 

The fellowship has established a textbook library available to all pediatric cardiology fellows.  

Individual office space and desktop computers are provided to each fellow. Laptop computers for rounding and conference presentations are available to the fellows.   

Please see the Department of Pediatrics fellowship page for departmental benefits available to all pediatric fellows, and the OHSU GME page for Employment and Benefits information, including salary, transportation, and insurance.

The pediatric cardiology fellowship program is structured to provide a challenging and rigorous training experience while supporting behaviors that establish a healthy work-life balance and nurture personal well-being. You will find that while the faculty and your co-fellows are committed to providing excellence in clinical care, and in contributing to the education and scholarship within our field, we are also well-rounded individuals devoted to our families and engaged in a variety of leisure activities.

Clinical training

Fellowship training is an intense and exhilarating immersion into all aspects of pediatric and congenital cardiology. We have structured our schedule to ensure that you will work at a pace that is appropriately challenging yet facilitates the educational opportunity in each experience.

Over the three years of fellowship training, you will be assigned to approximately 24 months of clinical rotations and be given a minimum of 12 months of research experience. Clinical rotations are interspersed across the three years of training so as to continually strengthen your knowledge and skill sets. In the second year, you will be assigned fewer clinical rotations to support and maximize research productivity. A sample curriculum is provided; however, one of the strengths of our program is that we are able to tailor each fellow’s training in a way that best suits their anticipated career direction, while at the same time providing a solid foundation of the fundamentals of our field.

The rotation schedule consists of 26 two-week blocks per academic year. Standard rotations include the cardiology inpatient and consult service, echocardiography, interventional cardiology, elective, and research. Fellows attend a continuity clinic each week with their assigned faculty mentor. Over the three years of training, fellows will also attend additional sub-specialty clinics, including Adult Congenital Heart Disease, Electrophysiology, Dyslipidemia, Pulmonary Hypertension and Single Ventricle clinic.  Attendance at one of the additional 14 outreach clinics across the region are encouraged as they are excellent training opportunities, but not required.

Didactic teaching and clinical conferences

Faculty from across the cardiac program contribute to the pediatric cardiology fellows’ didactic curriculum, which is updated each year and based in part on the content guidelines of the American Board of Pediatrics Subspecialty Examination. Fellows are excused from all clinical activities on Thursdays between 10-11:30am to attend these sessions.  

In addition to this curriculum, weekly and monthly didactic sessions are provided by the echo staff, electrophysiology staff, and the cardiovascular surgeons. Fellows review electrocardiograms with a faculty mentor every other week. A monthly teaching session covers interventional cardiology and angiography. Additional didactic sessions are provided by pediatric critical care, the Stanford Heart Transplant Program, the adult cardiology service, and the adult congenital cardiology program. For the coming year, our fellows will also participate in a cardiac critical care curriculum provided by Heart University. 

Fellows take a primary role in presenting the echocardiograms at our weekly Medical/Surgical Cardiology Conference. Fellows also lead our monthly Journal Club, the Cardiac Interventional Morbidity & Mortality Conference, as well as an every other month Non-Invasive Morbidity & Mortality Conference. 

The Department of Pediatrics presents a monthly didactic session for fellows across pediatric subspecialties within the department.

Scholarly activity

All fellows participate in a structured core curriculum in scholarly activities organized by the OHSU Human Investigations Program, supported by the Oregon Clinical and Translational Research Institute. In addition, fellows complete at least one research project typically culminating in a submitted manuscript and presentation at a regional or national conference. Each fellow will also submit at least one grant application to support their scholarly activity. Fellows work with research mentors as well as a Scholarly Oversight Committee, responsible for providing individual guidance and support to each fellow. Our goal is to provide fellows the experience and skills to become successful clinician scientists.

Fellows also participate in our patient safety and quality improvement projects. The Cardiac Program Operations and Quality Committees each provide mentorship and ideas for important QI projects.

Teaching Opportunities

Our fellows work closely with pediatric residents and medical students in the Intensive Care Unit, Emergency Department, Cardiac Ward, and Cardiology Clinic. There are numerous rewarding opportunities for the fellows to teach at the bedside, in didactic sessions and ad-hoc teaching environments. Our fellows are frequently honored for their teaching and clinical mentorship of pediatric residents and students. There are a number of faculty mentors available to fellows interested in making education a focus of their careers.
