Discrete subaortic stenosis in an adult patient

Abstract

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