PALMA, E.C., et al. : Histopathological Correlation of Ablation Lesions Guided by Noncontact Mapping in a Patient with Peripartum Cardiomyopathy and Ventricular Tachycardia. A patient with peripartum cardiomyopathy developed a nearly incessant nonsustained VT. Guided by a noncontact mapping system, the tachycardia was mapped to the mid‐septum of the right ventricle and ablated. Despite transient success, the tachycardia recurred and the patient subsequently died of multiorgan failure. Histopathological correlation of the ablation site revealed a nontransmural lesion that may have contributed to the failure of the ablation.
