Intracoronary stent implantation under intracoronary ultrasound guidance with aspirin and ticlopidine therapy.

Abstract:

OBJECTIVE:To observe the immediate angiographic and intravascular ultrasound (IVUS) results and their effects on one month clinical outcomes in forty-one patients who submitted to coronary stent deployment with IVUS guidance. METHODS:All patients were allocated to coronary stent implantation with high inflation pressure. After good angiographic results (< 20% residual stenosis), all patients underwent IVUS and higher-pressure dilatation would be necessary if criteria for optimal coronary stent implantation were not met. The optimal criterion of IVUS for stent implantation was the ratio of intrastent lumen cross-sectional area to the average of the proximal and distal reference lumen cross-sectional areas > or = 80%. All patients had aspirin and ticlopidine therapy on the day of angioplasty and during the one month follow-up period. RESULTS:Optimal criteria of IVUS were obtained without any further intrastent dilatation in twenty-five patients but intrastent higher-pressure dilatation was performed in fourteen patients whose ultrasound results did not reach the criteria. In these patients, we increased the minimal intrastent lumen area 25.7% (P < 0.05). Thirty-five patients (90%) had good minimal intrastent lumen area of IVUS. There were no deaths, myocardial infarction, acute stent thrombosis or need for revascularization during the study and the one month follow-up. CONCLUSIONS:Intracoronary stent deployment under IVUS guidance, including combining aspirin and ticlopidine therapy, had beneficial ultrasound results and good clinical outcomes after one month follow-up.
