Abstract:
Pulmonary vein stenosis (PVS) is a rare but potentially serious complication of atrial fibrillation (AF) ablation. We present a case of a 30-year-old male with a history of multiple radiofrequency ablations for AF who developed complete occlusion of the left superior pulmonary vein (LSPV) and near-complete stenosis of the left inferior pulmo nary vein (LIPV). The patient presented with palpitations and dyspnea, and imaging revealed marked post-ablation narrowing and collateral formation. Pulmonary venous stenting of the LIPV was successfully performed, resulting in symptomatic and anatomical improvement. This case highlights the importance of maintaining high clinical sus picion for PVS following AF ablation and demonstrates the role of timely imaging and intervention in preventing irreversible pulmonary damage.
