Effect of rotational angioplasty in treatment of patients with chronic coronary artery occlusions

Objective:To evaluate the effect of rotational angioplasty(RA) in the treatment of patients with chronic coronary artery occlusions.Methods:RA was performed on 21 patients with chronic coronary artery occlusions (RA),including 8 cases of PTCA failure, 8 patients whose TIMI was grade 1 and 13 patients whose TIMI was grade 0. The occlusion vessel involved LAD in 6 cases, LCX in 7 and RCA in 8. Results:Successful reopening was achieved in 13 patients. The success rate in patients with TIMI 1 was 100%, 75% in those whose occlusion duration was less than 3 months, and 40% in those whose occlusion duration was over 3 months. The longest occlusion duration was 16 months and the average occlusion duration was 8.12 months in those who was successfully treated.Conclusion:Rotational angioplasty is safe and effective in treating chronic coronary artery occlusions.
