Surgical repair of subaortic stenosis in atrioventricular canal defects.
A 6-month-old male infant with partial atrioventricular canal defect and subaortic stenosis had a mitral valve releasing procedure to correct the subaortic stenosis with concomitant repair of the canal defect. An echocardiogram done 1 year after the operation shows no subaortic gradient and no mitral regurgitation. We present the details of the surgical technique and the common pitfalls in recognizing and treating this entity.
