title: [Modified Konno procedure for a child with left ventricular outflow tract obstruction after repair of atrioventricular septal defect: a transaortic transpulmonary approach].
abstract: 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.
