[Safety, feasibility and efficacy of a new single-wire stent in the treatment of complex coronary lesions: the angiostent].
The angiostent is a single wire, flexible, highly radiopaque, balloon expandable stent. To evaluate the feasibility and safety of the deployment of this new stent, we report the clinical and procedural results of 70 procedures performed in 51 native coronary arteries of 48 patients, with objective evidence of ischemia. The target lesion was located in the left anterior descending artery in 18 (36%) cases, in the circumflex artery in 16 (31%) cases and in the right coronary artery in 17 (33%) cases. Mean reference vessel diameter was 3.2 +/- 0.4 mm and the minimal luminal diameter was 0.4 +/- 0.3 mm, with a mean diameter stenosis of 86 +/- 10%. Type B2 and C lesions were encountered in 56% of the cases. More than one angiostent was implanted in 14 vessels and multiple stenting was accomplished with the use of different stents in 8 coronary arteries. No major complications were reported. The post-procedural minimal luminal diameter was 3.2 +/- 0.4 mm with a mean diameter stenosis of 1.4 +/- 3.7%. In 25 cases (49%) major side branches raised from the stented segment and in all but one remained patent. In conclusion, the implantation of the angiostent is safe, feasible and effective, as it can be easily deployed at the lesion site, used for the treatment of complex lesions and preserves the patency of jailed side-branches.
