Key result
Repeat balloon angioplasty for pulmonary vein stenosis has no reported quantitative results or findings in the provided abstract.
Why the study?
The optimal treatment strategy for symptomatic pulmonary vein stenosis after pulmonary vein isolation for atrial fibrillation remains unknown, with stent restenosis occurring in up to 25% of cases and unclear antithrombotic regimens.
Does repeat balloon angioplasty improve long-term outcomes in patients with pulmonary vein stenosis after radiofrequency ablation?
Observational
Does repeat balloon angioplasty improve long-term outcomes in patients with pulmonary vein stenosis after radiofrequency ablation?
This case series investigates the long-term outcomes of repeat balloon angioplasty for pulmonary vein stenosis following radiofrequency ablation for atrial fibrillation.
Case series suggests possible benefit of repeat angioplasty; hypothesis-generating and should not yet change practice for post-ablation pulmonary vein stenosis.
Pulmonary vein stenosis (PVS) after pulmonary vein isolation (PVI) for atrial fibrillation (AF) is a rare but serious complication with significant morbidity.1 The optimal treatment strategy for symptomatic PVS remains unknown. Stenting is preferred to balloon angioplasty (BA) because it has a lower incidence of restenosis than BA.2–5 However, the incidence of stent restenosis is reported to be up to 25% during a 3-year follow-up.2 Moreover, appropriate antithrombotic therapy after stenting is unknown.
