A one-year-old infant underwent repair of atrioventricular septal defect with common orifice. About 2 years later, echocardiography revealed a left ventricular outflow tract obstruction for the first time. Because of progression of the obstructive lesion, a modified Konno procedure through a transaortic transpulmonary approach was later performed at 8 years old, and the postoperative course was uneventful. This is a useful procedure for left ventricular outflow tract obstruction with normal aortic valve and aortic annulus, because it can both preserve a native aortic valve and dose not necessitate right ventriculotomy in resection of hypertrophied muscle and patch enlargement of interventricular septum.
一名一岁婴儿接受了共同开口型房室间隔缺损修复术。约两年后，超声心动图首次显示左心室流出道梗阻。由于梗阻性病变进展，患儿8岁时经主动脉经肺动脉途径进行了改良Konno手术，术后恢复顺利。对于主动脉瓣和主动脉环正常的左心室流出道梗阻，这是一种有用的手术方法，因为它既能保留天然主动脉瓣，又无需在切除肥厚肌肉和扩大室间隔补片时进行右心室切开术。
