Risk of subsequent pregnancy in women with a history of peripartum cardiomyopathy.

Peripartum cardiomyopathy (PPCM) is a pregnancy-associated myocardial disease with marked left ventricular systolic dysfunction. Although this condition can lead to major complications, including severe heart failure, arrhythmias, thromboembolic events, and death, the majority of women with this condition demonstrate a complete or partial recovery. Many of these women desire to become pregnant again and are concerned regarding the safety of additional pregnancies. The purpose of this paper is to review the available information related to subsequent pregnancies in women with a history of PPCM in an attempt to reach conclusions regarding the risk of such pregnancies in this group of patients.
