The low pressure stent observational trial on the procedural and mid-term outcome of a trapezoid-shaped coronary stent (LOPSTER).

Background: Stent design influences the procedural and mid-term results of coronary interventions. The trapezoid-shaped struts of the low pressure stent (LP-Stent) might improve the outcome by reducing the vascular trauma at deployment.

Methods: A total of 133 patients (64.

Comparison of a silicon carbide coated stent versus a noncoated stent in humans: the Tenax- versus Nir-Stent Study (TENISS).

Purpose: Stents coated with hypothrombogenic silicon carbide (a-SiC:H) exhibited low restenosis rates in the rabbit and in an observational study in humans. Thus, the clinical and angiographic outcome was assessed in a large multicenter study.

Material And Methods: Four hundred and ninety-seven patients (63.

Comparison of a silicon carbide-coated stent versus a noncoated stent in human beings: the Tenax versus Nir Stent Study's long-term outcome.

Background: Stents coated with amorphous hypothrombogenic silicon carbide (a-SiC:H) have low restenosis rates in humans. Recurrence in a-SiC:H at mid-term follow-up has been shown to be similar to a stainless steel device. The long-term outcome, however, may be different.
