Cardiac disease in pregnancy: hypertrophic obstructive cardiomyopathy and pulmonic stenosis
The prevalence of cardiovascular disease in pregnancy is increasing and cardiovascular disease is the leading cause of pregnancy-related death in the United States.1 The physiologic adaptations to pregnancy include an increased heart rate, stroke volume, and substantial expansion in circulatory volume, which may pose significant cardiac stress to patients with cardiac disease. During labor, cardiac output increases further and maternal expulsive efforts during the second stage of labor, with the decreased preload and increased afterload that accompany the Valsalva maneuver, may provoke decompensation in vulnerable patients.
