BACKGROUND. In the past few years, the indications for stent implantation have broadened, along with a larger number of available designs. The Bard XT stent is a new modular stent with an original structure and design. METHODS. To evaluate the new Bard XT stent, we studied its use in a multicenter experience in 163 patients, with a total of 168 lesions and 180 implanted units. RESULTS. Despite the predominance of complex lesions, the procedural success rate was 98%, with only a 2% failure of stent implantation. There was only one death (no-fellow phenomenon in a rescue primary PTCA in a patient in cardiogenic shock) without other major periprocedural complications. Centralized QCA showed a statistically significant increase of MLD (from 0.73 ± 0.43 mm to 2.71 ± 0.40 mm, p <0.0001) and DS reduction (from 73.8 ± 15.1% pre-treatment to 7.8 ± 0.4% after stent implantation; p <0.0001). Aspirin and ticlopidine were routinely administered after the procedure. Thirty-day follow-up reported only one case of subacute stent thrombosis (in the first day), treated with re-PTCA. CONCLUSIONS. In a group of patients with complex lesions, we obtained a high rate of success with a low incidence of complications. The Bard XT stent had a high-performance profile with normalization of vessel diameter and angiographic results similar to the ones obtained with the 'slotted tube' stents.
