AbstractCardiomyopathy during pregnancy is uncommon but potentially catastrophic to maternal health, accounting for up to 11% of maternal deaths. Peripartum cardiomyopathy is diagnosed in women without a history of heart disease 1 month before delivery or within 5 months postpartum. About half of all women will have full myocardial recovery within 6 months of diagnosis, but complications such as severe heart failure or death are not rare. African-American women have higher rates of diagnosis and adverse events. Women with preexisting cardiomyopathy, such as dilated or hypertrophic cardiomyopathy, followed closely during pregnancy often tolerate pregnancy and delivery. Risk factors for adverse outcomes include functional status at baseline, severity of systolic dysfunction or outflow tract gradient, or history of prior cardiac event, such as arrhythmia or stroke. The level of brain natriuretic peptide (BNP) can be used to risk stratify women for adverse events. Pregnant women with cardiomyopathy should be followed closely by a multidisciplinary team comprised of nurses, obstetricians, neonatologists, cardiologists, anesthesiologists, and cardiac surgeons.Copyright © 2014 Elsevier Inc.
