We present a new operation that combines the concepts of aortoventriculoplasty, extended aortic root replacement, and the use of a pulmonary autograft. Fourteen patients underwent this operation: 9 patients after previous attempts to relieve diffuse subvalvular stenosis and 5 patients who had excessive gradients over an outgrown aortic valve prosthesis. All patients except 1 survived the operation. Complete heart block developed in 1 patient after a septal infarction. One patient remained in congestive heart failure and died suddenly after 17 months. All other patients are in New York Heart Association class I after a mean follow-up of 20 +/- 12 months. All patients showed excellent function of the autograft and homograft valve at follow-up. This operation might present a more durable or even a definitive solution in the management of these complex left ventricular outflow tract obstructions.
