Percutaneous coronary atherectomy early experience of King Faisal specialist hospital and research centre

ABSTRACT

Between November 1991 and March 1994, we performed 66 percutaneous coronary atherectomy procedures using Simpson atherocaths in 59 males and seven females with a mean age of 52 +/- 10.9 years and a mean CCS anginal class of 2.8 +/- 0.9. Vessels recanalized patients. The mean size of the artery dilated was 3 +/- 0.4mm. Additional intervention was one in 27.3% to achieve optimal residual lumen. Success rate was 97%. Emergency CABG surgery was required in one patient who died one week postoperatively. Follow up catheterization in patients who had finished six months post procedure showed a restenosis rate of 27.3%. We conclude that the procedure has a high success rate and acceptable complication rate and can be used in revascularization of arteries with large size and suitable eccentric lesions
