TCT-660 Repeat Vascular Brachytherapy for Recurrent In-Stent Restenosis in Patients With Failed Intracoronary Radiation Therapy

In-stent restenosis (ISR) is an Achilles’ heel of percutaneous coronary intervention (PCI). Balloon angioplasty, vascular brachytherapy (VBT), drug-eluting stents, and drug-coating balloons have been used for the treatment of ISR. For patients in whom VBT for prior ISR is unsuccessful, the
