Key result
Stenting for post-PVI PVS is linked to ~470% greater freedom from re-intervention versus balloon dilation.
Why the study?
Outcome reports of percutaneous intervention for pulmonary vein stenosis resulting from pulmonary vein isolation were limited.
Does stent implantation reduce the need for re-intervention compared to balloon angioplasty in patients with pulmonary vein stenosis after pulmonary vein isolation?
Population
172 patients with 276 veins analyzed for PVS after PVI
Comparison
Stent implantation vs balloon angioplasty
Design
Single-center retrospective review
Follow-up
5 years

Stenting was associated with fewer re-interventions in post-PVI stenosis; leaves open optimal strategy pending randomized trials.

Does stent implantation reduce the need for re-intervention compared to balloon angioplasty in patients with pulmonary vein stenosis after pulmonary vein isolation?
Effect estimate: HR 5.7
Absolute Event Rate: 73% vs 23%
p-value: p=<.001
Stent implantation, particularly with stents ≥7 mm, is associated with significantly lower rates of re-intervention compared to balloon angioplasty for pulmonary vein stenosis after pulmonary vein isolation.
Suntharos et al. (2019) conducted a cohort in Pulmonary vein stenosis after pulmonary vein isolation (n=172). Stent implantation vs. Balloon angioplasty was evaluated on Freedom from re-intervention at 5 years (HR 5.7, p=<.001). Stent implantation for pulmonary vein stenosis after pulmonary vein isolation yielded greater 5-year freedom from re-intervention than balloon dilation (73% vs 23%; HR 5.7, p<0.001).
