Abstract
We performed primary directional coronary atherectomy (DCA) without antecedent thrombolytic therapy in 21 of 67 patients with acute myocardial infarction within 24 hr of onset between June 1993-March 1994. Reperfusion with primary DCA was successful in 18 patients (85.7%, group D). Results were compared with those of primary balloon angioplasty patients treated between June 1992-May 1993 (group P). Minimum lumen diameter (MLD) values both immediately after reperfusion and in predischarge angiograms were significantly larger in group D than in group P, but were similar in late follow-up angiograms. Although a larger MLD in group D than in group P contributed to the prevention of reocclusion of the coronary artery before discharge in DCA patients, a high rate of restenosis at late follow-up canceled the beneficial effects of primary DCA.
