Reverse "U" aortotomy for aortic valve replacement after previous coronary artery bypass grafting.
The presence of patent vein grafts on the proximal aorta may give technical difficulties during exposure to aortic valve replacement after previous coronary artery bypass operations. A tongue or reverse "U" shape aortotomy allows excellent exposure of the aortic valve and antegrade cardioplegic administration without mobilizing vein grafts. This approach may facilitate uni- or bidirectional aortic root enlargement in patients with small aortic root.
