Figure 1 Percentage of diameter stenosis measured by quantitative coronary angiography before intervention ( ), after excimer laser treatment ( ), after adjunctive balloon angioplasty (+) and at six-month follow-up (x) in 89 patients. The percentage of diameter stenosis decreased significantly after laser treatment and further after adjunctive balloon angioplasty (p < 0.001). At follow-up there was a significant late lumen loss which translated into an increase of diameter stenosis (p < 0.001).
