title: [Implantation of coronary stent during the acute phase of myocardial infarction for treatment of dissection or partial result after angioplasty. Immediate results and angiographic follow-up].
abstract: Between December 1991 and November 1994, a Palmaz-Schatz stent was implanted in 9 patients aged 57 +/- 14 years during the acute phase of myocardial infarction after primary angioplasty in 7 cases and salvage angioplasty in 2 cases after an interval of 175 mm +/- 62 mn from the onset of infarction, because of threatening dissection (N = 8) or a partial result (N = 1). The success rate of implantation was 100% with residual stenosis (DCI Philips system) measured at 16 +/- 8% (5 to 28%). Anticoagulant treatment comprised heparin, coumadin and aspirin in two cases, and, in the following 7 cases, low molecular weight heparin, ticlopidine and aspirin. There was one death due to cardiogenic shock on the third day despite intraaortic balloon pumping. One patient was operated for a femoral aneurysm. A prophylactic bypass procedure was performed as a semi-emergency in a stable patient. At systematic angiographic control, the residual stenosis was measured at 19 +/- 14% (10 to 43%) without reocclusion. There was no recurrence of ischaemia. The authors conclude that the encouraging results of this short series suggest that despite the highly thrombogenic situation of acute myocardial infarction and despite the context of emergency implantation of a stent. Palmaz-Schatz stent implantation gives good immediate and long-term results with respect to reocclusion and stenosis.
