Postpartum cardiomyopathy is a serious disorder that can present from the third trimester to up to 5 months after pregnancy. Although spontaneous resolution of cardiac function occurs in more than half of patients (over a period of 6-12 months), the balance is left with persistent cardiac dysfunction. Cardiac dysfunction results in signs and symptoms of left heart failure, formation of apical or left ventricular thrombi, and arrhythmias and requires management similar to that in patients with nonischemic dilated cardiomyopathy.
