This video tutorial presents the case of surgical correction of left outflow tract obstruction after atrioventricular septal defect repair. The left outflow tract obstruction was presented as a fixed fibromuscular membrane combined with accessory tissues from the left atrioventricular valve. The surgical correction included fibromuscular membrane resection combined with myotomy and resection of additional tissues arising from the atrioventricular valve. The repair was conducted via a transaortic approach. Post-operative echocardiography demonstrated a good result of the surgery without flow acceleration across the left ventricular outflow tract and minimal aortic valve insufficiency. The patient is doing well at 7 months follow-up.
