Abstract

Objectives

We aimed to compare long-term clinical outcomes between modified mini-crush (modi-MC) technique with classic crush (crush) technique for treatment of bifurcation lesions.

Background

The modi-MC technique showed excellent procedural success and favorable 9-month clinical outcomes.

Methods

From January 2005 to November 2009, we enrolled patients with de novo bifurcation lesions treated with modi-MC (n= 112 lesions in 111 patients) and crush technique (n= 69 lesions in 67 patients). Primary endpoint was rate of major adverse cardiac events (MACE), a composite of all-cause death, myocardial infarction (MI), and target lesion revascularization (TLR) at 3 years.

Results

There was no significant difference in baseline characteristics. The modi-MC technique showed a significantly higher success rate of final kissing balloon inflation (84.1 vs. 98.2%,P= 0.001). After 3 years, MACE rate was significantly lower in the modi-MC group (25.4 vs. 12.6%,P= 0.030). The incidence of all-cause death was 7.5 vs. 2.7% (P= 0.087), MI was 4.5 vs. 1.8% (P= 0.290), TLR was 17.4 vs. 8.9% (P= 0.093) and stent thrombosis was 3.0 vs. 1.8% (P= 0.632) in the crush and modi-MC groups, respectively.

Conclusions

The modified mini-crush technique showed more favorable 3-year clinical outcomes compared to the classic crush technique. © 2012 Wiley Periodicals, Inc.
