Atrial Fibrillation Ablation-induced Pulmonary Venous Occlusion Requiring Pneumonectomy

Ann Thorac Surg. 2023 Feb;115(2):e33-e35. doi: 10.1016/j.athoracsur.2022.03.005. Epub 2022 Mar 22.

Abstract

A 71-year-old woman with a history of atrial fibrillation underwent a catheter-based ablation procedure. Months later, she presented with dyspnea and a left-sided pleural effusion. Diagnostic evaluation revealed left-sided pulmonary venous occlusion, with essentially absent left lung perfusion. The patient underwent left pneumonectomy, with left atrial appendage occlusion. Although lobectomy for pulmonary venous occlusion of a single vein after pulmonary vein isolation has been described, this appears to be a novel report of occluded pulmonary venous drainage of an entire lung necessitating pneumonectomy.
