Acute and long-term clinical and angiographic outcome after S-Stent implantation: S-Stent multicenter safety and efficacy trial.
The purpose of this study is to demonstrate safety and effectiveness of the S-Stent in de novo coronary lesions treated with conventional percutaneous coronary balloon angioplasty. Between January 2000 and June 2001, 120 patients were prospectively enrolled at four study centers. Patients were treated with coronary stenting in a total of 137 lesions. Procedural success was achieved in 100% of 137 attempted lesions. Clinical success was 99.8%. In-hospital mortality was 0.8%; myocardial infarction occurred in 0.8% and stent thrombosis in 0.8%. After stent implantation, the minimal lumen diameter increased from 0.92 +/- 0.43 to 2.74 +/- 0.36 mm (P < 0.0001) and the percent diameter stenosis decreased from 68.0 +/- 16.2 to 4.5 +/- 12.0 (P < 0.0001). At 6-month follow-up, the percent diameter stenosis was 33.5 +/- 21.3 and the angiographic restenosis rate was 16.5%. Target lesion revascularization was required in 12 patients (10.1%). We conclude that the use of S-Stent for coronary intervention resulted in a high procedural success rate and low angiographic restenosis at 6 months after implantation.
