Key result
Redo radiofrequency catheter ablation for atrial fibrillation resulted in the severe complication of symptomatic stenosis of all four pulmonary veins in a 61-year-old patient.
Why the study?
Symptomatic pulmonary vein stenosis is one of the most severe complications following radiofrequency catheter ablation for atrial fibrillation.
Case Report (n=1)
This case highlights the severe complication of pan-pulmonary vein stenosis following redo radiofrequency ablation for atrial fibrillation.
Prompts vigilance for pulmonary vein stenosis after redo AF ablation; leaves open optimal prevention strategies.
Radiofrequency ablation is the "gold standard" in atrial fibrillation treatment. The frequency of complications is about 3.5-3.9 %. The symptomatic pulmonary vein stenosis is one of the most severe complications. In this report we present a clinical case of stenosis of all four pulmonary veins after redo catheter ablation of atrial fibrillation in 61year-old patient, and discussion of possible causes, specific features of diagnosis, and possible approaches to treatment of this complication.

Меркулов et al. (2019) conducted a case report in Atrial fibrillation (n=1). Redo radiofrequency catheter ablation was evaluated on Pulmonary vein stenosis. Redo radiofrequency catheter ablation for atrial fibrillation resulted in the severe complication of symptomatic stenosis of all four pulmonary veins in a 61-year-old patient.
