Abstract
A 35-year-old woman was referred to our hospital for the management of acutely decompensated heart failure due to peripartum cardiomyopathy (PPCM). Generally, cardiac examinations are performed after the manifestation of heart failure in patients with PPCM. Thus, reports of serial cardiac examinations before the onset of PPCM are scarce. In this case, we were able to document the serial echocardiographic findings before the onset of life-threatening PPCM. We found that the left ventricular systolic function was preserved at 35 weeks of gestation but declined acutely after delivery at 38 weeks. Although speculative, these findings suggest that left ventricular dilation might precede the onset of PPCM.
