title: Repair of atrioventricular canal associated with membranous subaortic stenosis.
abstract: The successful repair of associated atrioventricular canal anomaly and membranous subaortic stenosis is reported for the first time in two patients. Although subaortic stenosis associated with atrioventricular canal anomaly has been reported previously, it was caused by anomalous positioning of the atrioventricular valve, so that the discrete membranous type of stenosis in these two patients is the unique feature. Awareness of the possible association of these two deformities should enable accurate preoperative diagnosis and simultaneous correction at operation.
