Rotational Atherectomy for the Management of Undilatable In-Stent Restenosis with Single or Multiple Stent Layers
Abstract
Background
There is no consensus on the best treatment of undilatable coronary in-stent restenosis (ISR) regardless of the number of stent layers. We aimed to evaluate the procedural and clinical outcomes of rotational atherectomy (RA) to treat undilatable coronary ISR with single or multiple stent layers.
