Peripartum cardiomyopathy (PPCM) is a form of heart failure (HF) that develops towards the end of pregnancy or within the first months after delivery.1 Rates of thromboembolism in PPCM are reportedly higher than in many other cardiomyopathies.2 In the United States, thromboembolism was the most common serious complication in PPCM, occurring in 6.6% of affected women.3 In the multinational European Society of Cardiology (ESC) EURObservational Research Programme (EORP) PPCM registry, 5% of patients had a thromboembolic event (TE) during the index hospitalization.4
