Cardiac Surgery

Surgery performed when one or more of the coronary arteries in the heart are narrowed or blocked by atherosclerosis (hardening of the arteries). The surgeon takes a graft, usually from a vein in the leg, an artery in the chest wall, or forearm. One end of the graft is attached to the aorta, the largest blood vessel, or some other blood supply, and the other end is attached to the coronary artery, beyond the blockage, restoring blood flow to the heart.

Surgery is performed when one or more of the four valves in the heart is damaged by age, congenital defect, infection, or rheumatic heart disease. This may be necessary when the valve becomes too narrow (stenosis) or it doesn't close properly (regurgitation or insufficiency). Valves may be amenable for repair or require replacement with artificial biological or mechanical valves.

A surgical procedure developed by James Cox, MD, that permanently repairs atrial fibrillation, returning the patient to normal sinus rhythm.

Surgery performed in a manner which minimizes trauma to the patient. This is most relevant to some coronary  artery bypass surgery, which can be performed without the use of the heart lung machine (off pump surgery).

Aortic and Aortic Root Pathology

This surgery often involves concomitant valve or bypass surgery, and usually involves the replacement of part of the aorta due to dilation (aneurysm) or tearing (dissection).
