Abstrakt: Objective: To investigate effects of stent flexibility on 6 months' clinical and angiographic outcome in long stented lesions. Design: A total of 44 genuine coronary artery lesions (lesion length >20 mm and ≤30 mm) were randomized to implantation with a 30 mm long flexible coiled stainless steel stent (Freedom Force[sup ®], Global Therapeutics) (n = 23) or a 30 mm long stiff tubular stainless steel stent (Crown[sup ®], Johnson & Johnson) (n = 21). Results: Target vessel revascularization was performed in 10 patients (45%) in the Freedom Force[sup ®] stent group, and in 7 patients (33%) in the Crown[sup ®] stent group (ns). No significant differences concerning minimum lumen diameter (MLD), early gain, late loss or binary restenosis rate were seen. In the Freedom Force[sup ®] stent group all restenoses were located within the stent. In the Crown[sup ®] stent group three (27%) of the restenoses were located at the edge of the stent (ns). Conclusion: In a limited number of patients no significant differences could be detected in clinical or angiographic parameters between patients treated with long tubular or long coiled stents.
