Key result
A 35-year-old pregnant woman with a congenital subaortic membrane presented with heart failure and a peak systolic gradient of 132 mmHg, the highest reported in the literature.
Why the study?
Severe fixed left ventricular outflow tract obstruction due to congenital subaortic membrane in pregnancy is rare and not well characterized.
Case Report (n=1)
Highlights a rare case of very severe fixed left ventricular outflow tract obstruction due to a congenital subaortic membrane presenting with heart failure during pregnancy.
Alerts clinicians to extreme severity possible in pregnant patients with subaortic membrane; extends reported spectrum but remains hypothesis-generating.
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.

Elyas et al. (2022) conducted a case report in Severe subvalvular aortic stenosis (n=1). Congenital subaortic membrane was evaluated on Peak systolic gradient. A 35-year-old pregnant woman with a congenital subaortic membrane presented with heart failure and a peak systolic gradient of 132 mmHg, the highest reported in the literature.
