Does catheter ablation for atrial fibrillation lead to pulmonary vein occlusion?
Total pulmonary vein occlusion is a severe complication of atrial fibrillation ablation that can mimic primary lung disease and is prone to restenosis after recanalization.
Ernst et al. (2003) conducted an observational in Atrial fibrillation (n=239). Catheter ablation was evaluated on Total pulmonary vein occlusion. Catheter ablation for atrial fibrillation resulted in total pulmonary vein occlusion in 3 of 239 patients (1.3%), presenting with severe respiratory symptoms mimicking primary lung disease.
