Cardiovascular Disease Fellowship Training Program

The Cardiovascular Disease Fellowship Training Program at Tufts Medical Center provides trainees with the necessary skills to become exceptional specialists. Fellows are integrated into all aspects of the Division of Cardiology and the CardioVascular Center, providing bedside care, mastering procedural skills and participating in educational and research activities.

During the 3 to 4 year, fully ACGME/RRC-accredited training program, Fellows participate in clinical rotations involving a variety of aspects of inpatient and outpatient cardiovascular care, including cardiac catheterization, echocardiography, nuclear cardiology, advanced cardiac imaging with CT/MR, electrophysiology, heart failure, cardiac intensive care, vascular medicine, community cardiology and preventive cardiology.

Following core cardiovascular training, Fellows are provided an opportunity to concentrate on sub-specialized training and research with advanced training in electrophysiology, interventional cardiology, heart failure and transplant. In addition, fellows have many research opportunities to pursue in basic and translational science at the Molecular Cardiology Research Institute as well as specialized research training in the Institute for Clinical Research and Health Policy. Fellows work closely with house staff and medical students as both consultants and educators.

The goal of the program is to produce well-trained, clinically-savvy, compassionate cardiologists. The training program has a rich tradition of training well-rounded physicians in all aspects of cardiovascular medicine. Our competency-based goals include:

  • Patient care – fellows demonstrate compassionate, appropriate and effective care.
  • Medical knowledge – fellows demonstrate knowledge about established and evolving biomedical, epidemiological and socio/behavioral sciences and demonstrate application of this knowledge to patient care.
  • Practice-based learning and improvement – fellows develop expertise in critical analysis of clinical problems and appropriate decision-making.
  • Interpersonal communication – fellows exhibit exceptional abilities to communicate with patients, families and health care teams.
  • Systems-based practice – fellows develop a larger awareness of the availability and proper utilization of resources when caring for cardiovascular patients.
  • Professionalism – fellows are encouraged to join local and national organizations, adhere to ethical principles and display sensitivity to diverse patient populations.

The Cardiovascular Disease Fellowship Program exposes trainees to an excellent case mix during their monthly rotations through the various subspecialties in cardiology. Fellows learn from a wide variety of clinical pathology and graduate as superb cardiologists capable of treating any cardiovascular patient. During their inpatient and outpatient rotations, fellows are exposed to a number of our major clinical programs, including:

  • Coronary heart disease
  • Heart failure
  • Cardiomyopathies
  • Electrophysiology
  • Cardiovascular imaging
  • Interventional cardiology
  • Valvular heart disease
  • Preventive cardiology and risk factor management
  • Pulmonary heart disease
  • Peripheral vascular disease
  • Infections and inflammatory heart disease
  • Women and heart disease
  • Diseases of the great vessels
  • Adult congenital heart disease
  • Cardiovascular surgery

Graduates from the Tufts General Cardiology Fellowship Program frequently pursue additional training to serve as sub-specialists in a variety of fields. Many fellows stay at Tufts MC for advanced training in the following ACGME-accredited training programs. 

Participation in cardiovascular research is an important part of the fellowship program at Tufts Medical Center. From early on in the fellowship years, trainees get involved in the numerous opportunities that we offer in basic and translational science, clinical projects and population research.

Each Fellow completes academic projects during fellowship and presents their findings at divisional conferences as well as local, national and international forums. The Fellows Research Forum allows trainees to present their research proposals and later their results to the entire faculty. Fellows interested in a career in basic science have unique opportunities in the Molecular Cardiology Research Institute at Tufts Medical Center. The MCRI focuses on the study of molecular mechanisms of human disease, incorporating translation of bench findings to new bedside strategies for diagnosis and therapy. The MCRI is fortunate to have a fellowship training grant sponsored by the National Institutes of Health to provide trainees hands-on experience to pursue careers in the biological sciences with a focus on cardiovascular research.

Fellows interested in clinical care and outcomes have the opportunity to work with the Division of Clinical Care Research at Tufts Medical Center. Members of this Division are interested in factors that affect clinical care and are developing treatment strategies, decision aids and computer-based systems to improve health outcomes. Post-doctoral training may be provided by the Division’s training grant in clinical care research.

In addition to the individualized instruction given throughout each rotation, fellows are taught through didactic sessions, interactive conferences and self study.

The core curriculum includes a Fellows’ Conference, the Cardiology Division Conference, EKG Conference, Cath Lab Conference, Preventive Cardiology Conference, Cardiology Grand Rounds, Imaging Conference and Medical Grand Rounds. Additional conferences include a Morbidity/Mortality Conference, Research Methodology Conference, Heart Failure Research Conference and Electrophysiology Conference.

Fellows have access to a full range of inpatient, outpatient, clinical and research laboratory facilities. The Naimi Fellowship Room, along with recently renovated Levine and Criscitiello Conference Rooms, provide centrally-located, dedicated workspace that is equipped with state-of-the-art educational resources. Fellows have access to a complete medical library through the Tufts University School of Medicine, as well as numerous on-line educational tools.

Our trainees spend the majority of their time at Tufts Medical Center.  To complement this training, fellows spend time at MelroseWakefield Hospital (Melrose, MA) and MetroWest Medical Center (Framingham, MA). During these rotations, fellows gain experience in consultative cardiology, critical care cardiology, non-invasive imaging and cardiac rehabilitation. Dedicated interventional and electrophysiology laboratory exposure is also provided to fellows during their community cardiology rotations. Teaching and supervision is performed by academically-trained and affiliated cardiologists, many of whom are trained at Tufts MC. 

Our outstanding faculty members are among the nation’s leaders in bringing the latest advances in cardiovascular diagnosis and care into clinical practice. Tufts Medical Center cardiology faculty are full-time academic staff dedicated to teaching fellows. All patient encounters and procedures performed by fellows are supervised by attending cardiologists.
