Severe Subvalvular Aortic Stenosis in a Pregnant Woman

Abstract

A 35-year-old pregnant female in her second trimester presented with heart failure manifestations with evidence of very severe fixed left ventricular outflow tract obstruction. The peak systolic gradient was 132 mmHg, which is the highest reported in the literature, secondary to congenital subaortic membrane. Similar case reports that we could find in the literature were reviewed to highlight the importance of such anomaly.
