Discrete subaortic stenosis in an adult patient

Abstract

Discrete subaortic stenosis is an unusual cause of the left ventricular outflow tract obstruction in the adultsand characterized by a discrete subaortic membrane. A 52-year-old female patient presented with chiefcomplaints of progressive dyspnoea, chest pain and fatigue. Echocardiographic study showed a discretefibromembranous ridge located in the subaortic region, which resulted in severe subaortic stenosis, with a mildaortic regurgitation and a mean gradient of 65 mmHg. She underwent surgical resection of the subaorticmembrane without any complications. The postoperative course was uneventful, and she was discharged fromhospital on the 7thpostoperative day. At one-year postoperative follow-up, the patient was doing well withoutrecurrence on echocardiogram. A close follow-up is mandatory for a possible recurrence despite sufficientsurgical resection.
