A case report of paroxysmal atrial fibrillation in three pulmonary veins presenting a common trunk.

ABSTRACT:

Background

The pulmonary vein (PV) variant is present in 23-38% of patients who undergo atrial fibrillation ablation, and the common inferior PV (CIPV) variant is a rare PV variant that has been reported in 0.9-1.5% of patients. The arrhythmogenicity of the common trunk of the CIPV is unknown.

Case summary

A 77-year-old woman underwent catheter ablation for paroxysmal atrial fibrillation (AF). Preoperative computed tomography revealed a common trunk from which the bilateral inferior PVs and a left superior PV originated. The voltage map of the left atrium (LA) showed three PVs stemming from a common trunk. There was a low-voltage area bounded by the common trunk entrance. An isolation line was created to connect the right superior PV and the common trunk. Twelve months later
