Abstract:
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.
