Physician Biography

Primary focus and interest includes mitral valve repair surgery specifically minimally invasive approaches such as keyhole surgery through small incision in the right chest or robotic mitral valve surgery. Additional interest is aortic valve repair, valve sparing root replacement, transcatheter valve procedures, thoracic endovascular aneurysm repair, and robotic coronary revascularizaton. 

Yale Cardiac Surgery consistently outperforms on a local and regional level in respect to surgical outcome as demonstrated by multiple 3-Star rating by the Society of Thoracic Surgeon (STS) Public reporting ( for aortic valve replacement, mitral valve procedures as well as combined valve and coronary artery bypass surgery.
