Video 9. After plaque modification with the excimer laser, there is full uniform expansion of NC Quantum 2.0 mm balloon at 12 atm. After two passes with the laser catheter, an NC Quantum Apex 2.0mm x 12mm non-compliant balloon was then able to successfully dilate the lesion, with the residual waist yielding at less than 12 atmospheres of pressure (Figures 8 and 9, Videos 9 and 10). Following this, the lesion was treated with tandem Promus Premier (Boston Scientific) drug-eluting stents (2.25mm x 24mm and 2.25mm x 8mm).
