Peripartum cardiomyopathy (PPCM) is the most common cardiomyopathy in pregnancy. It is potentially life-threatening. It is, diagnosed in women without a history of heart disease 1 month before delivery or within 5 months. It is marked by heart failure and left ventricular dyshfunction. The evolution is favorable. LV function improves within 6 months in the majority of patients, but long-lasting mortality and morbidity are not infrequent. Recent work suggests the critical toxic role for late-gestational hormones on the maternal vasculature and the genetic underpinnings of PPCM. Complications include different types of supraventricular and ventricular arrhythmias, heart failure and ischemic stroke. The brain natriuretic peptide (BNP) can be used to risk stratify women for adverse events. Management of peripartum cardiomyopathy is based on treatment of heart failure. The addition of bromocriptine seemed to improve LVEF. Close monitoring of pregnant women with cardiomyopathy by multidisciplinary team is recommended.
