Aims: To assess the safety and efficacy of the XTENT customisable drug-eluting stent system in the treatment of patients with single long or multiple coronary lesions referred for PCI.
Methods and results: The CUSTOM-II trial enrolled 100 patients with de novo lesions in native coronary arteries presenting with either single long lesions (n=69) of > or =20 mm length or up to two lesions with a total cumulative anticipated stent length of 60 mm of stent (n=31). Patients were assessed angiographically at six months, and clinically at one year. Of the 100 patients enrolled, nine patients experienced a MACE, including five patients whose MACE occurred during index hospitalisation (two non-Q-MI, two Q-MI and one probable stent thrombosis-related death), and four target lesion revascularisations (TLR) at six months. No MACE or stent thrombosis was reported between six and 12 months follow-up. In-segment late loss at 6-months was 0.22 +/- 0.28 mm, and in-stent late loss had a range of 0.31 +/- 0.31 mm.
Conclusions: The XTENT customisable stent is clinically safe and efficacious as judged by angiographic and clinical variables through 12 months follow-up. Further follow-up and larger randomised comparative studies are needed for its clinical positioning.
