Key result
Stenting small coronary arteries with BeStent small or NIR-7 resulted in no significant differences in predefined endpoints, with an overall 88.5% freedom from MACE at 6 months.
Why the study?
Does the BeStent small compared to the NIR-7 stent improve clinical and angiographic outcomes in patients requiring stenting for small coronary arteries after suboptimal balloon angioplasty?

Does the BeStent small compared to the NIR-7 stent improve clinical and angiographic outcomes in patients requiring stenting for small coronary arteries after suboptimal balloon angioplasty?
Provisional stenting of small coronary arteries using either the BeStent small or NIR-7 stent is feasible and safe, yielding favorable mid-term clinical and angiographic outcomes with no significant difference between the two devices.
Comparable outcomes support either stent for small vessels; extends RCT evidence for provisional stenting after suboptimal angioplasty.
This prospective study assessed the feasibility, safety, as well as clinical and angiographic outcome after 6 months in 96 patients (100 lesions) treated by stent implantation after a suboptimal balloon angioplasty result in coronary arteries < 3 mm and with a lesion length < 25 mm. The lesions were randomized to treatment with BeStent small or NIR-7. Final quantitative coronary angiography was performed off line. Baseline reference diameter was 2.58 +/- 0.22 mm. Complex lesions constituted 52%, and 23% had unstable angina. Angiographic and procedural success was achieved in 98% and 94%, respectively. At follow-up, 88.5% were free of major adverse cardiac events. The overall restenosis rate was 22.5% (89% angiographic follow-up). There were no statistically significant differences between the stents regarding predefined endpoints. Thus, provisional stent treatment of small coronary arteries using BeStent small or NIR-7 is feasible, safe, and has a favorable clinical and angiographic mid-term outcome.

Moer et al. (2000) conducted an RCT in Suboptimal balloon angioplasty result in small coronary arteries (n=96). BeStent small vs. NIR-7 stent was evaluated on Predefined endpoints (including major adverse cardiac events and restenosis). Stenting small coronary arteries with BeStent small or NIR-7 resulted in no significant differences in predefined endpoints, with an overall 88.5% freedom from MACE at 6 months.
