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.

Clinical and angiographic procedural and mid-term outcome with new versus reused balloon catheters in percutaneous coronary interventions.

Background: To reduce procedural cost, cardiac centers increasingly use resterilized balloon catheters for percutaneous coronary interventions. Data addressing the procedural and mid-term outcome in a prospective randomized trial comparing new and resterilized balloons are not available.

Methods And Results: Percutaneous coronary interventions were performed at random in 238 consecutive patients with either new or 1-3 times reused balloon catheters.

Evaluation of the Coroflex Theca-Stent for reduction of restenosis (ECORI).

Background: Various stent coatings have been shown to significantly reduce restenosis rates in comparison to non-coated devices. Therefore, the short- and mid-term performance of the new polyphosphazene-coated Coroflex Theca-Stent was investigated.

Methods: 103 patients [63.

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.

[Long-term outcome in patients with angina-like chest pain and normal coronary angiograms].

Background: Short-term prognosis of patients with chest pain and angiographically smooth coronary arteries is good in terms of development of coronary events (fatal or nonfatal myocardial infarction, coronary death, new coronary heart disease), but long-term studies are rare.

Patients And Methods: 185 consecutive patients (mean age 54 +7.8 years, 59% male)with typical angina pectoris or atypical chest pain who underwent coronary angiography between 1980 and 1989 and had completely normal coronary arteries and left ventricular function (mean ejection fraction 68%) were followed over a period of 12.

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.
