Intravascular Lithotripsy for the Treatment of Calcium-Mediated Coronary In-Stent Restenoses.

BACKGROUND Coronary intravascular lithotripsy (IVL) has recently been evaluated for the treatment of severely calcified native coronary lesions. Evidence for its use in in-stent restenosis is sparse and is still an off-label indication. Therefore, we aimed to evaluate the feasibility, safety, and acute and mid-term angiographic outcomes after IVL for the treatment of calcium-mediated coronary in-stent restenosis. METHODS A retrospective,...
