Elective sirolimus-eluting stent implantation for multivessel disease involving significant LAD stenosis: one-year clinical outcomes of 99 consecutive patients--the Rotterdam experience.

The aim of this study was to evaluate the effectiveness of sirolimus-eluting stent (SES) implantation for patients with multivessel disease, which included left anterior descending artery (LAD) treatment. Since April 2002, SES has been utilized as the device of choice for all interventions in our institution as part of the Rapamycin-Eluting Stent Evaluated at Rotterdam Hospital (RESEARCH) registry. In the first 6 months of enrollment, 99 consecutive patients (17.6% of the total population) were treated for multivessel disease involving the LAD. The impact of SES implantation on major adverse cardiac events (MACE) was evaluated. All the patients received SES in the LAD. Additional stent implantation in the right coronary artery, the left circumflex, or in all three major vessels was attempted successfully in 32 (32%), 51 (52%), and 16 (16%) of the treated patients respectively. During a mean follow-up of 360 +/- 59 days (range, 297-472 days), we had one death, one non-Q-wave myocardial infarction, and eight patients required subsequent intervention. The event-free survival of MACE at 1 year was 85.6%. SES implantation for multivessel disease in a consecutive series of patients is associated with low incidence of adverse events. The reported results are related predominantly to the reduction in repeat revascularization.
