| | Dr. David A. Brown and Dr. Fraser Keith specialize in adult cardiac surgery including:
- Coronary Artery Bypass 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 is attached to the coronary artery, beyond the blockage,
restoring blood flow to the heart.
-
- Heart Valve Repair and Replacement
- 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. Homografts are human valves used in
special cases primarily to repair pulmonic or aortic valves.
-
- Cox-Maze Surgery
- A
surgical procedure developed by James Cox, MD, that permanently
repairs atrial fibrillation,
returning the patient to normal sinus rhythm.
-
- Minimally Invasive Surgery
- Surgery performed in a manner which minimizes trauma to the patient.
this is most relevant to some coronary artery 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).
