This study aimed to demonstrate the dynamic changes of tissue characteristics in patients with peripartum cardiomyopathy (PPCM). Cardiovascular magnetic resonance (CMR) examination was performed using a 3.0T MR scanner, consisted of a MOLLI sequence for T1 mapping, and a T2 prep with bSSFP for T2 mapping. Ten PPCM patients with repeated CMR and 20 healthy age-matched females were analyzed. After a median 15.3-month follow-up, five patients had a recovered left ventricular ejection fraction. PPCM patients showed significantly higher native T1, extracellular volume, and T2 than normal controls. Furthermore, native T1 decreases significantly in the follow-up CMR of PPCM patients.
