Fig 1 (A) After exposure of the aortic valve leaflets, an intraoperative cardioscope (4-mm, 30-degree angled) is advanced to explore the subaortic area. A discrete subaortic membrane can be seen. (B) After the subaortic fibromembrane has been incised and removed, repeat inspection of the subaortic area with an endoscope confirms that there is no residual obstructive lesion. The left ventricular outflow tract can be clearly seen. The Annals of Thoracic Surgery 2000 69, 1273-1275DOI: (10.1016/S0003-4975(99)01536-2)
