A hybrid procedure consisting of total thoracoscopic ablation followed by an electrophysiological study successfully treated persistent AF in a patient with a rare congenital pericardial defect and LAA herniation.

Incidental CPD with LAA herniation during TTA for AF requires intraoperative awareness; hypothesis-generating for congenital anomalies in persistent AF.
Congenital pericardial defects (CPDs) are infrequent anomalies that are usually asymptomatic and are discovered incidentally during unrelated interventions. Here we report the case of a CPD with herniation of an enlarged left atrial appendage identified during total thoracoscopic ablation (TTA) for persistent atrial fibrillation (AF). The persistent AF was successfully treated with a hybrid procedure, in which TTA was followed by an electrophysiological study.
