- W2045192009 abstract "Elective high pressure stent implantation in focal coronary lesions has a high procedural success and low incidence of restenosis in comparison with balloon angioplasty. For the treatment of diffusely diseased coronary arteries, however, a high incidence of subacute thrombosis and late restenosis has been reported. The aim of this study was the prospective evaluation of procedural and long-term outcome after implantation of multiple stents. In a consecutive series of 48 patients, 48 lesions were treated with the implantation of 120 stents (2.5 ± 1.0 stents/lesion). Stent implantation was performed electively in 15%, for dissection in 56%, and for suboptimal balloon angioplasty result in 29% of patients. The lesion length before stenting, including balloon angioplasty induced dissections, was 28.5 ± 9.8 mm (range 20–62), the mean length of the stented segment was 40 ± 16 mm. The procedure was successful in 45 patients (95%). Procedural related complications included two urgent bypass operations (4%) and one transmural myocardial infarction (2%). Two subacute stent thrombosis events (4%) occurred, both in-hospital, 1 and 3 days after implantation. Follow-up was obtained in 43 eligible patients at 6.4 ± 1.3 months, revealing an overall restenosis rate of 30% (13 patients). Quantitative angiography (CAAS II, edge detection algorithm) showed a minimal lumen diameter of 0.93 ± 0.28 mm (diameter stenosis 62%± 13%) before treatment, 2.81 ± 0.26 mm (diameter stenosis –4 ± 13%) after stenting, and 1.79 ± 0.58 mm (diameter stenosis 30%± 20%) at follow-up. Predictors of restenosis were not identified. Thus, multiple stent implantation has high procedural success and the late restenosis of long lesions after multiple stents compares favorably with balloon angioplasty." @default.
