Meet Our Structural Heart Team

The transcather aortic valve replacement program (TAVR) started at the UA Sarver Heart Center in 2012 under the leadership of Kapil Lotun, MD, an interventional cardiologist who has clinical expertise in structural heart disease and congenital heart defects. The TAVR procedure is a minimally invasive catheter-based treatment option for patients who are considered "high or medium" risk to survive open-heart surgery to replace aortic valves affected by severe aortic stenosis. In this condition, the valve does not open properly and blood cannot leave the heart chambers to get out to the rest of the body.

The team includes specially trained cardiologists, cardiothoracic surgeons, nurse practitioners, nurses and medical assistants, plus other health professionals.
