Abstract

Aim: The aim of the present study was to assess the safety and efficacy of percutaneous coronary interventions (PCI) using the new Polish stent "Chopin" (Balton, Poland).
Methods: The study consisted of experimental and clinical parts. In the experimental phase, the new stent was implanted into 5 pigs and control coronary angiography as well as intracoronary ultrasonography (ICUS) were performed 30 days later. In the clinical phase, 101 patients (57% of males, mean age 55.6±10 years) with symptomatic coronary artery disease (CAD) with "de novo" coronary lesions (including 12% of patients with unstable angina and 19% with acute myocardial infarction [MI]) underwent stent implantation. The patients were followed for 6 months for the occurrence of cardiac events. Quantitative coronary angiography was performed at baseline and after 6 months.
Results: 50% of vessel lumen) was documented in 18.8% of cases. The mean late vessel lumen loss was 0.77±0.6 mm, and stenosis - 29.1±20%. The restenosis rate was significantly higher in patients with unstable angina rather than in those with stable angina or acute MI.
Conclusions.: Implantation of the new Polish stent "Chopin" during PCI is safe and effective.
