Valved Conduit Attached to Left Ventricular Outflow Tract for Valve Detachment in Behçet's Disease.

Standard aortic valve replacement for aortic regurgitation caused by Behçet's disease is frequently complicated by postoperative recurrent prosthetic valve detachment. To prevent this, we have developed a modified Bentall procedure, in which the valved conduit is proximally attached to the left ventricular outflow tract instead of to the fragile annulus, based on the fact that the left ventricular outflow tract myocardium is rarely involved in Behçet's disease. This modified Bentall procedure was performed in 5 Behçet's disease patients with prosthetic valve detachment after primary aortic valve replacement, and satisfactory results were achieved.
