Keri Shafer | Professional History

My current practice includes inpatient and outpatient care at caring for adults with congenital heart disease and pulmonary hypertension. In addition, I am part of the echocardiography labs at BCH and Brigham and women’s hospital focusing on adult congenital and stress cardiac imaging. As part of my goal to improve ACHD care locally, I was fortunate to have the opportunity to also collaborate with colleagues at Boston Medical Center in starting an ACHD clinic. My current and past research efforts focus on better understanding the response to exercise in those with congenital heart disease. Additionally I served on the guidelines committee for the ACC/AHA regarding sports participation in those with congenital heart disease.

From medical school in home state of New Mexico to finishing my training here at Boston Children’s Hospital, each segment of my training was profoundly useful and important to learning comprehensive, evidence based care. My goal is to provide care to my patients as if they were my family. One of the biggest parts of that is thinking about each patient as a whole person. Each aspect of their care is important, not just congenital heart disease or pulmonary hypertension. I enjoy being a physician the most when I can spend time getting to know my patients and helping to keep their heart disease as only a small part of their life. For that reason, I often focus on the importance of staying active and incorporating exercise into daily life.

Medicine is the perfect combination of meaningful work and science. I love cardiology- the heart is a beautifully designed system that is a source of endless fascination for me. However, I stay in medicine because I love patient care. There is nothing more rewarding than to take a patient through critical illness and then to see them live a life without limitation from their heart disease. I also enjoy teaching my patients about ways to lead healthy lives and how to understand their heart disease.
