Comparison of one-year clinical outcomes between intravascular ultrasound-guided versus angiography-guided implantation of drug-eluting stents for left main lesions: a single-center analysis of a 1,016-patient cohort.

ABSTRACT:

Background

The importance of intravascular ultrasound (IVUS)-guided stenting of the unprotected left main coronary artery (ULMCA) remains controversial and has not been fully studied in the subset of patients with ULMCA. This study evaluated the clinical outcome of IVUS-guided stenting using a drug-eluting stent for ULMCA.

Methods

A total of 1,016 consecutive patients with ULMCA stenosis who underwent drug-eluting stent implantation from January 2006 to December 2011 were prospectively registered. The primary endpoint of this nonrandomized registry was the rate of one-year major adverse cardiac events (MACE, including cardiac death, myocardial infarction, and target vessel revascularization). Stent thrombosis served as the safety endpoint. Propensity score matching was used
