Abstract
The surgical relief of complex multilevel left ventricular outflow tract obstruction remains a challenging surgical problem. We present a new operation which combines the concepts of aortoventriculoplasty, extended aortic root replacement and the use of a pulmonary autograft. Fourteen patients underwent this operation: nine patients after previous attempts to relieve diffuse subvalvular stenosis and five patients who presented excessive gradients over an outgrown aortic valve prosthesis. All patients except one survived the operation. One patient developed complete heart block after a septal infarction.
One patient remained in congestive heart failure and died suddenly after 17 months. All other patients are in NYHA 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.
