UNLABELLED: Peripartum cardiomyopathy (PPCM) is a poorly characterized, rare form of cardiomyopathy. The etiology of PPCM is unknown, but viral, autoimmune, and idiopathic causes may contribute. The presentation is similar to other forms of congestive heart failure; the diagnosis of PPCM should not be considered until other causes of cardiac dysfunction are ruled out. Echocardiography is central to diagnosis. Early diagnosis and initiation of treatment are essential to optimize pregnancy outcome. Intensivists and anesthesiologists should be consulted to assist with management in complicated cases. Management of PPCM is essentially supportive. Prognosis is poor, although cardiac transplant is improving prognosis and should be considered when conventional therapy fails. TARGET AUDIENCE: Obstetricians & Gynecologists, Family Physicians LEARNING OBJECTIVES: After completion of this article, the reader will be able to understand the typical presentation of peripartum cardiomyopathy including adverse outcome predictors, to understand how to make the diagnosis of PPCM and how to manage it, and to understand the natural history of the disease.
