title: Surgical management of tunnel-like subaortic stenosis via ventricular septal defect in a patient with the interrupted aortic arch.
abstract: A 24-day-old male with interrupted aortic arch (type B), ventricular septal defect, and tunnel-like subaortic stenosis underwent a one-stage surgical treatment. The operative procedure comprised reconstruction of the aortic arch, transatrial excision of the subaortic fibromuscular tissue via the ventricular sepatal defect, and patch closure of the defect. The patient tolerated the procedure well and the postoperative echocardiography demonstrated a residual pressure gradient across the left ventricular outflow tract of 20 mmHg. Our result suggests that the transatrial surgical management of subaortic stenosis via the ventricular sepatal defect produces a safe and promising surgical option.
