In‐Hospital and 12‐Month Postprocedural Clinical Outcome of Coronary Bifurcational Lesion Treatment with the Endeavor Stent

Background: The zotarolimus‐eluting stent (ZES) has been documented as significantly reducing restenosis and target lesion revascularization (TLR) requirement compared to bare metal stents (BMS). Methods: In this single‐centered, prospective study we sought to evaluate the short‐ and medium‐term outcomes of ZES placement in bifurcated coronary artery lesions. Between August 2006 and December 2007, 107 consecutive patients (110 bifurcations) were recruited to have ZES placement in the lesion. The provisional T stenting (PTS) technique was used in 96.3%. Angiographic success was 100% in main vessel (MV) cases and 97.2% in that of side branch (SB). Results: With a mean follow‐up of 12.4 ± 1.77 (mean ± SD) months there were four deaths, three from cardiac cause (2.85%). There were 18 patients (19 bifurcations) requiring TLR (17.59%) for clinical reasons. The only predictor of TLR was the use diameter of ZES ≤3 mm. Conclusion: ZES can be used for bifurcation lesions using the PTS technique with a high rate of intraprocedural success; however, frequency of TLR is high, especially for stents with a diameter ≤3 mm.
