ABSTRACT


AIMS - With newer drug-eluting stents (DES), PCI has appeared as an acceptable alternative to cardiac surgery in the treatment of unprotected left main (ULM) lesions. Using data from the French Left Main Taxus and the LEft MAin Xience registries, we compared two-year outcomes in consecutive patients from 2003-2008 using everolimus-eluting stents (EES) vs. paclitaxel-eluting stents (PES).


METHODS AND RESULTS - We performed a matched comparison according to SYNTAX score, distal LM stenosis, provisional side-branch T-stenting and single stent use, focusing on the primary endpoints of target vessel MI (TVMI) and target vessel failure (TVF). After propensity score matching, there were 172 patients in each group. There was no difference in gender (76.5% male), age (69.5 ± 11.3 years), diabetes (26.2% vs. 24.4%, p=0.71), NSTEMI (40.7% vs. 40.7%, p=1), or LVEF <40% (11.0% vs. 6.7%, p=0.22). Patients with distal LM lesions (75.9%) were treated using provisional T-stenting in 91.1%. The side branch was stented in 22% of all patients (p=0.51). Cumulative two-year events showed significant differences in TVMI (9.9% vs. 4.1%, p=0.04) and TVF (16.3% vs. 7.6%, p=0.01) for PES and EES, respectively.

CONCLUSIONS - ULM stenting with EES is safer and more effective than PES with a reduction in TLF by 53% at two years.
