Subaortic membrane in an adult patient with coronary artery disease.

A case of subaortic membrane with coronary artery disease in a 48-year-old man is described. He was referred to our hospital for cardiac murmur, which was discovered on routine clinical examination. He had no significant past medical history apart from dizziness while exercising. Subaortic membrane was totally excised; left internal thoracic artery was anastomosed to left anterior descending artery by end-to-side technique. The postoperative 2-year course of the patient was uneventful.
