One of the special things about electrophysiology here is that we have we have a really large department. We have 13 electrophysiologists, which is more than some cities have. A unique aspect of Duke is that there is a lot of collegiality among our providers. We certainly approach patients as a team. That’s a huge benefit for patients coming to Duke. With such a large and unique department, we’re certainly able to deal with many complex patients. Some of my favorite patients are those I have followed for years. It’s an ongoing relationship that I have and seeing them come back and telling me about all the wonderful things they are doing is really satisfying.

I am an interventional cardiologist and researcher who has been at Duke for nearly 20 years. I enjoy being at Duke because of the “family” I get to work with every day. When we are able to make a patient feel better through teamwork; it’s a great feeling. I chose cardiology as my specialty because of the chance to make a difference in someone’s life in real time. When someone is having a heart attack, they are relying on you to come to their aid quickly. At that moment, I get to apply science to save a life, while learning more about what we can do to help improve people’s lives in the future. In that way, medicine also gives me the chance to learn from my patients and apply what I find to benefit the greater good. I find that whole process is exciting. When I am not at work, I enjoy spending time with my school-aged children. Dr. Patel is rated as an Experienced provider by MediFind in the treatment of Cardiomyopathy.

I came to Duke as a visiting medical student many years ago and fell in love with this institution and its people. I love to be part of a group that contributes knowledge and discoveries every day. As an electrophysiologist, I treat people with heart rhythm disorders, including atrial arrhythmias like atrial fibrillation and ventricular arrhythmias. I mostly focus on the prevention of sudden cardiac death and on patients with devices such as pacemakers and implantable defibrillators. We do everything we can to build a very good and strong relationship with patients; we provide them with the information they need and empower them to make the decisions that are best for them. We’re also at the cutting edge of new discoveries. The research we do is amazing – the findings that help patients and advance the field make working at Duke thrilling. It’s very exciting to be part of that. For these reasons, patients benefit greatly from coming to Duke. Dr. Al is rated as an Experienced provider by MediFind in the treatment of Cardiomyopathy.

I am a physician assistant at the outpatient cardiology clinic and have been in this position more than 15 years. I’m from Pennsylvania originally and initially had a job doing HIV research here at Duke. I discovered I enjoyed spending time in clinic more than research, so that led me to pursue the physicians assistant program. I enjoy helping patients and figuring out what they need—not only medically, but also socially. This includes supporting patients who need help paying for their medication or understanding their treatments and treatment options. Working through these issues can be very rewarding when patients come back and are clearly doing better. When patients thank me for helping them achieve or move closer to their health goals, I feel very happy. I have three young girls, so I spend a lot of time with them and outdoors. Dr. Povsic is rated as an Experienced provider by MediFind in the treatment of Cardiomyopathy. Her top areas of expertise are Angina, Glucocorticoid-Remediable Aldosteronism, Hypertension, and Coronary Heart Disease.

I fell in love with cardiology early in my medical training when I saw a patient in the emergency department who came in with a heart attack. The cardiology team swooped down and took him away to a procedure room, and in less than 45 minutes the heart attack had been stopped, and the patient was asking if he could go home. I'm so happy to be on that team now. I have extensive experience in minimally invasive procedures to treat people with a myriad of cardiac conditions. Most commonly, you can find me in the cardiac catheterization laboratory opening blockages in the arteries that feed the heart to treat angina or stop heart attacks. In the hospital, I also see patients with other acute cardiac conditions. In the office, I see patients with the entire range of heart problems. I'm excited to be joining Duke because I'll also be able to get back to doing research aimed at improving our understanding and management of patients with heart disease at the Duke Clinical Research Institute. In addition, I love to teach and learn, and there is no better place than Duke to stoke the intellectual curiosity that brought me to medicine in the first place.
