Key result
Balloon angioplasty guided by integrated backscatter intravascular ultrasound was utilized to treat a case of pulmonary vein stenosis caused by radiofrequency ablation for atrial fibrillation.
Why the study?
Catheter ablation for AF carries a risk of serious complications such as pulmonary vein stenosis, with an incidence up to 31.4%.

This case report describes the use of integrated backscatter intravascular ultrasound to guide balloon angioplasty for the treatment of pulmonary vein stenosis following atrial fibrillation ablation.
In recent years, there has been an increase in the number of cases involving catheter ablation for atrial fibrillation (AF). Because of this increased incidence, there is a high risk of encountering serious complications. Pulmonary vein stenosis (PVS) is a known complication of catheter ablation for AF. Existing literature shows that the incidence of this complication is up to 31.4% at present.1 Previous studies have reported the efficacy of catheter intervention for the treatment of PVS, including balloon angioplasty and stenting.
