Long-term Clinical Outcomes of Excimer Laser Coronary Atherectomy for the Management of Recurrent In-stent Restenosis

Recurrent in-stent restenosis (ISR) remains a serious problem. Optimal modification of the underlying mechanism during index percutaneous coronary intervention (PCI) is key to prevent ISR. Excimer laser coronary atherectomy (ELCA) has its own indications and is among others used in recurrent ISR in case of stent underexpansion and/or diffuse neointimal hyperplasia. We aimed to assess the long-term clinical outcomes of ELCA for the management of recurrent ISR.
