Figure 1 (A) Coronary angiogram with an in-stent restenosis (arrow) of a right coronary artery with three implanted Palmaz-Schatz stents. (B) Eccentric laser catheter with 2.0-mm tip (arrow) advanced in the stented portion of the vessel. The radiopaque marker band at the catheter tip, which allows control over the catheter rotation, is clearly visible. (C) Smooth ablation of plaque after multiple passes with the laser catheter under continuous saline flush (arrow). (D) Final angiogram after adjunctive percutaneous transluminal coronary angioplasty of the lesion (arrow).
