Notes:
The Tenax coronary stent is laser sculpted from high precision 316 L stainless steel using advanced production procedures. An a-Sic : H (hydrogen-rich amorphous silicon carbide) coating reduces its thrombogenicity and improves its biocomputibility. From April to July 1998, 266 stents were implanted in 241 patients (aged 62.7 ± 10.8 years) in five centers. The clinical indication for intervention was unstable angina (33.2%) and recent myocardial infarction (29.8%) in many cases. Most lesions (83.8%) had complex characteristics (Class B2 or C). The target vessel was the LAD in 42.8% and the right coronary artery in 36.8% of all cases. Four primary stent deployment failures occurred and implantation was successful in 289 (97.4%) of 266 stents. No death and no Q-wave myocardial infarction or emergency CABG occurred during hospital stay. Clinical success, defined as successful deployment without procedural or clinical event, was achieved in 230 (98.4%) of 241 patients. One-year clinical follow-up shows a low need for target lesion revascularization (17/237 [7.1%] patients) and a 15.8% rate of major adverse cardiac events (36/237 patients). The clinical and angiographic outcomes of our study suggest that the hybrid, amorphous hydrogenated silicon carbide coated design is promising and merits further evaluation in larger clinical trials.
