Cardiomyopathies and heart failure

Treatment of heart failure in pregnancy is based on the respective guidelines for the treatment of heart failure with some pregnancy-specific limitations. Cardiomyopathies are a rare but serious cause of heart failure and currently the most frequent cause of maternal mortality in pregnancy. All forms of cardiomyopathies may occur in pregnancy but peripartum cardiomyopathy is a specific and dangerous manifestation. Some new treatment options are arising based on its specific pathophysiology. Dilated cardiomyopathy has a high risk of deterioration in pregnancy. In contrast, hypertrophic cardiomyopathy is frequently tolerated well. Delivery should be well planned and some limitations on breastfeeding should be considered.
