Mid-ventricular obstructive hypertrophic cardiomyopathy during pregnancy complicated by preeclampsia and acute myocardial infarction: a case report.

Hypertrophic cardiomyopathy (HCM) with mid-ventricular obstruction (MVO) is a rare condition occurring in 1% of HCM patients. It is characterized by asymmetric left ventricular hypertrophy with MVO and elevated intraventricular pressure gradients. Myocardial infarction has been associated with mid-ventricular obstructive HCM. Briefly, this case presents an unusual clinical scenario where a young pregnant woman complicated by preeclampsia presents with myocardial injury and hemodynamic compromise related to undiagnosed HCM with MVO illustrating hemodynamic challenges created by pregnancy and surgery.
