Key result
Stent-in-stent strategy successfully treats pulmonary vein in-stent restenosis in a single case over 3 years.
Why the study?
Pulmonary vein restenosis occurs in up to 50% of cases, and while balloon angioplasty is widely preferred, alternative treatment strategies are needed.
Does a stent-in-stent strategy improve symptoms in patients with pulmonary vein in-stent restenosis?

Does a stent-in-stent strategy improve symptoms in patients with pulmonary vein in-stent restenosis?
A stent-in-stent strategy is a viable alternative for treating pulmonary vein in-stent restenosis with potentially favorable long-term outcomes.
May offer a treatment option for pulmonary vein in-stent restenosis; hypothesis-generating and requires prospective validation.
INTRODUCTION: Pulmonary vein (PV) restenosis develops with reported incidence rates of up to 50%. Balloon angioplasty seems to be the widely preferred treatment of choice. METHOD AND RESULTS: A 54-year-old man with long history of atrial fibrillations developed PVS secondary to multiple radiofrequency ablation procedures. The stenosis was treated with a stent. 8.5 years later he presented with an in-stent restenosis that was successfully treated with a stent-in-stent strategy. He has since remained asymptomatic over 3 years of follow-up. CONCLUSION: Our case demonstrates stenting as a viable alternative strategy with potentially favorable long-term outcome.

Buzwani et al. (2024) conducted a case report in Pulmonary vein in-stent restenosis (n=1). Stent-in-stent strategy was evaluated on Symptom status. A stent-in-stent strategy successfully treated pulmonary vein in-stent restenosis in a 54-year-old man, who remained asymptomatic over 3 years of follow-up.
