Implication

May support stenting for symptomatic post-ablation PV stenosis; leaves open need for controlled trials before wider adoption.

Key Points

To evaluate the feasibility, safety, and clinical efficacy of angioplasty and stent implantation in patients with acquired pulmonary vein stenosis following radiofrequency ablation.
Six patients with seven iatrogenic pulmonary vein stenoses, identified via multislice computed tomography, underwent catheterization and angiography between June 2003 and June 2004 in Milan, Italy.
Stenosed vessels were treated with balloon angioplasty and stent implantation, with anatomical patency and clinical outcomes tracked via follow-up imaging and clinical evaluations.
Five of seven stenoses were successfully treated with stenting, while one was untreated due to endoluminal thrombosis and one failed recanalization.
Angiography showed vessel diameter expanded from 1.7 ± 0.5 mm to 8.2 ± 0.8 mm (P < 0.05), with zero procedure-related major adverse events.
At a median follow-up of 17.1 months, all treated patients experienced minimal or absent symptoms, with vein patency confirmed by multislice CT at a median of 16.4 months.

Structured PICO

Does angioplasty and stent implantation improve symptoms and vessel patency in patients with acquired pulmonary vein stenosis after radiofrequency ablation?

Population

6 patients with 7 acquired iatrogenic pulmonary vein (PV) stenoses after radiofrequency ablation for atrial fibrillation, symptomatic (NYHA functional class II or III)

Intervention

Angioplasty and stent implantation

Outcome

Vessel diameter increase, procedural safety, symptomatic improvement, and PV patency at follow-upsurrogate

Angioplasty with stent implantation is a feasible and safe treatment for acquired pulmonary vein stenosis following radiofrequency ablation, providing symptomatic improvement and sustained vessel patency.
