The ISAR-CALC 2 trial is an investigator-initiated, prospective, randomized, multicenter, assessors-blind, open-label other clinical investigation. The objective of this trial is to investigate final angiographic minimal lumen diameter (MLD) following a strategy of super high-pressure balloon (OPN NC) versus intravascular lithotripsy (IVL) for drug-eluting stent (DES) implantation in severely calcified coronary lesions.
