A Young Pregnant Woman with Aortic Coarctation and Hypertrophic Cardiomyopathy

Pregnancy outcomes are negatively impacted by hypertrophic cardiomyopathy (HCM) and aortic coarctation (CoA), two distinct and independent cardiovascular conditions. Aortic aneurysms, hypertension, ischemic stroke, and re-coarctation are among high rates of cardiac complications seen in patients with repaired CoA. Modified World Health Organization (mWHO) maternal cardiovascular risk classification now categorizes pregnant women with repaired CoA in mWHO class III, whereas those with unrepaired severe CoA have been classified in mWHO class IV. Patients with HCM are categorized as mWHO II–III based on whether they have left ventricular outflow obstruction.
