Coronary atherectomy. An alternative to balloon angioplasty.
To date, physicians at our hospital have performed coronary atherectomy on 15 patients. Of these patients, four needed open heart surgery. One patient needed surgery because a vessel was dissected during the procedure, and the three other patients had unsuccessful procedures. One patient died due to a cerebrovascular bleed related to the anticoagulation therapy required for the procedure. Of the remaining patients, three had no reocclusion and four had reocclusion at their six-month follow-up examinations. The remaining patients have not had a six-month follow-up examination. The restenosis rate at our institution is 25%. It is hoped that catheter-mediated atherectomy will be an effective, predictable transluminal treatment of single or multiple focal stenosis. Because of the small patient sampling and short duration follow-up, no trends have been established. A six-month follow-up with angiography will establish patency and restenosis rates.
