title: Modified Bentall operation with bioprosthetic valved conduit: Columbia University experience.
abstract: A conduit was made by sewing a bovine pericardial valve into a graft conduit with the pseudo-sinuses of Valsalva. The graft collar below the valve cuff ring was sewn to the aortic annulus with interrupted pledgeted sutures. From August 2005 to February 2008, 68 patients underwent aortic root replacements with this technique. Operative mortality was 2.9% (2 acute aortic dissection patients died). During median follow-up of 11 months, 1 patient had reoperation for conduit failure due to infectious endocarditis. This technique is safe and feasible with favorable early outcomes. Because the valve is sewn above the outflow tract, superior hemodynamics are achieved. Reoperation may be accomplished by removal of the valve rather than full root re-replacement.
