Intravascular ultrasound-guided drug-coated balloon venoplasty for in-stent restenosis in pulmonary veins stenosis: a case report.

Nowadays, percutaneous approach is preferred and among percutaneous treatments for PVS, stenting has shown better results than balloon angioplasty (BA). Despite this, experience in in-stent restenosis is limited, and there is a lack of adequate and specific material for its approach. In this case, we present the possible role of the IVUS and the drug-coated BA in this entity.
