title: From aortic cusp extension to valve replacement with stentless pericardium.
abstract: Between 1988 and 1994, 82 consecutive patients (median age 24 years) underwent reconstruction of the aortic valve with glutaraldehyde-treated pericardium. Simultaneously, 29 of 30 mitral valves were repaired. The first 27 patients underwent resection of the free edges and suture of a single strip of bovine pericardium. Transient ischemic changes suggested the need for a change in technique. The subsequent 55 patients underwent total valve reconstruction with an autologous pericardium fixed with glutaraldehyde in the appropriate shape and size according to the patient's aortic annulus. There were one in-hospital and three late deaths. No patient received anticoagulation, and no embolic events were detected. Nine patients required reoperation as a result of failure of mitral valve repair in 4 and severe aortic regurgitation in 5 (endocarditis [n = 2], commissural tear [n = 1], root dilation [n = 1], calcification of one bovine cusp [n = 1] at 58 months). There were no reoperative deaths. Complete linear echocardiographic follow-up of these patients showed low gradients, valve competence, and no progressive deterioration. No difference between techniques was detected.
