Department and Faculty

Cardiology fellow with advisor

Cardiologists in the Department of Cardiovascular Diseases at Mayo Clinic's campus in Rochester, Minnesota, provide the best possible care to patients with disorders of the heart, arteries, veins, and lymphatic vessels.

Supported by many laboratories, subspecialty clinics, preventive health programs, basic and clinical research programs, and continuing education programs, cardiologists offer patients the latest in new diagnostic techniques, drugs, and interventions through a highly integrated, cooperative group practice.

The Center for Congenital Heart Disease on the Rochester campus offers specialized care to adult patients with congenital heart disease.

From the director

Crystal Bonnichsen, M.D., Director of Adult Congenital Heart Disease FellowshipWelcome! The Adult Congenital Heart Disease Fellowship at Mayo Clinic offers the unique opportunity to train at an institution with a history of providing excellent care to patients with congenital heart disease. Our fellowship began in 1991, and more than 25 fellows have completed this program. Many of these individuals are now leaders in the field of congenital heart disease.

Mayo Clinic has been consistently ranked as one of the top institutions in the country in cardiovascular care and cardiac surgery. We have expertise in every area of cardiology and cardiovascular surgery and an integrated multidisciplinary practice with a history of providing care to patients with complex congenital heart disease.

The objective of this fellowship is to train future leaders in the field of adult congenital heart disease by using Mayo Clinic's three-shield approach: clinical practice, education, and research.

We see more than 2,000 outpatients every year in our Adult Congenital Heart Disease Clinic, and you will gain clinical expertise in the management of all aspects of congenital heart disease in adults. You will work closely with experts in the field of adult congenital heart disease and have opportunities to participate in educational conferences on a daily basis. We offer many opportunities for research, and our fellows regularly present at national and international meetings.

This website will provide you an overview of our fellowship and our approach to patient care, education, and research. If you have additional questions, contact us for more information. Thank you for your interest in our program.

Program Director


The Adult Congenital Heart Disease Clinic is staffed by six fully trained adult congenital cardiologists and three nurses. Faculty members in the clinic have a wealth of experience in the clinical care of patients with congenital heart disease, and many have been instrumental in national organizations and the development of American College of Cardiology and American Heart Association guidelines for the care of these patients.

As a fellow, you also work closely with colleagues in pediatric cardiology, congenital cardiac surgery, and congenital electrophysiology. We have 13 pediatric cardiologists and four surgeons with expertise in the treatment of congenital heart defects, and five electrophysiologists with expertise in managing patients with congenital heart disease.

These faculty members are committed to teaching and facilitating the growth of medical knowledge. They have published and lectured extensively and are highly regarded in their fields. You have direct access to these individuals and work one-on-one with them throughout your training in the Adult Congenital Heart Disease Fellowship.

Advisers and mentors

Faculty advisers are available to provide comprehensive educational advice and personal support. You meet with your adviser periodically throughout the program to review your progress and career goals and to ensure that your educational needs are being met. Your adviser may serve as a contact point for introducing you and your family to Rochester, Minnesota, and the Mayo Clinic system.

Visiting professors

Many prominent professors visit Mayo Clinic each year. They present their work during lectures, participate in hospital rounds, and have informal discussions with trainees.

Visiting professors specific to congenital heart disease include the Carole A. Warnes Lectureship in Adult Congenital Heart Disease and the David J. Driscoll Lectureship in Pediatric Cardiology. Many additional visiting professors in other areas of cardiology visit Mayo Clinic each year. We encourage you to attend those presentations.
