Abstract

We report two cases undergoing electrophysiological studies for ventricular arrhythmias (VAs) associated with peripartum cardiomyopathy. Those two cases demonstrated that subsequent pregnancies might result in deterioration of VAs even though they exhibit no symptoms of heart failure. Those findings may clinically impact the decision making when women with a history of peripartum cardiomyopathy desire to become pregnant again. The VA foci in both cases were determined or suggested to be in the epicardium of the ventricular outflow tract from the results of the catheter ablation and electrophysiological study. Therefore, catheter ablation of those VAs may be feasible but challenging.
