Minimally invasive approaches to aortic valve surgery: Brigham experience

Aortic valve surgery is a proven and effective therapy for severe aortic stenosis and insufficiency. Conventional aortic valve surgery is performed with a full sternotomy, cardiopulmonary bypass, and replacement of the diseased aortic valve. Unlike minimally invasive (or "off-pump") coronary artery bypass, minimally invasive aortic valve surgery still requires cardiopulmonary bypass but refers primarily to smaller incisions and access. Minimally invasive approaches to aortic valve surgery have evolved over the past decade and have become the standard in institutions that perform large-volume minimally invasive cardiac surgery. The upper hemisternotomy has become our standard approach to isolated aortic valve surgery. It is a safe and effective technique with a similar morbidity and mortality to conventional aortic valve surgery. Patients derive clear benefits from this minimally invasive approach including less pain, shorter length of hospital stay, and faster return to preoperative function levels.
