title: Valve placement in the ventricular apex for complicated left ventricular outflow obstruction.
abstract: Successful correction of severe valvular calcific aortic stenosis is described in which a stented porcine aortic heterograft was placed in the ventricular apex. Creation of a double outlet is a valid alternative approach to relieve left ventricular hypertension, and indication for such a procedure may be encountered unexpectedly. Intramyocardial placement of a durable tissue valve provides a simple and effective option for the cardiac surgeon.
