Familial occurrence of peripartum cardiomyopathy: Genetic origin, unrecognized dilated cardiomyopathy or chance effect?

There have been rare case series with familial clustering of peripartum cardiomyopathy (PPCMP). Due to the concomitant occurrence of PPCMP and idiopathic dilated cardiomyopathy, it has been suggested that genetics might play a role in the pathogenesis of PPCMP. Herein, we report four cases of PPCMP in the same family, who showed full recovery of left ventricular function within a short period. <Learning objective: Physicians caring for peripartum cardiomyopathy (PPCMP) patients should be aware that PPCMP may have a genetic background and guidelines for diagnosis of genetic cardiomyopathy should be considered.>.
