Objective

Since the recognition that atrial fibrillation(AF) may originate from triggers within the pulmonary veins(PVs) and that ablation can eliminate these triggers, interest in PV anatomy has increased. Variations in number and insertion of PVs have been described. This study aims to investigate PV anatomy and its variations in a sample of Turkish patients undergoing PV isolation (PVI) for AF.

Methods

250 patients who were admitted for cryoballoon- based PVI for AF, underwent multidetector computed tomography before cryoablation. PV and left atrial(LA) anatomy were evaluated on three- dimensional epicardial reconstructions.
