Abstract

Excimer laser coronary angioplasty has been shown to result in high acute success rate. However, long term follow up has shown significant restenosis. To evaluate the restenosis predictive factors, we analyzed data from patients treated by excimer laser angioplasty in four French clinical centers. A cohort of 166 patients, 140 men and 26 women with mean age of 58 +/- 11 years, was enrolled in the study. Total occlusions, tubular, ostial and calcified lesions, unsuccessful balloon dilatation and/or restenosis were considered as indications for laser angioplasty. Follow-up angiography six months after the procedure was achieved in 80 patients. In conclusion, excimer laser angioplasty is associated with a high initial success rate and an acceptable major complications rate. However the use of this method is limited by significant restenosis rate.
