Peripartum cardiomyopathy--three cases.

Three cases of peripartum cardiomyopathy (PPCM) are presented, each illustrating a clinically important aspect of the disorder. One patient survived despite extreme haemodynamic deterioration, one died suddenly 2 months post partum although clinically recovered, and one died during a subsequent pregnancy. The cases demonstrate the severity and the unpredictable course of PPCM, which remains a challenge both to scientists and to clinicians.
