Intravascular ultrasound-guided systematic two-stent techniques for coronary bifurcation lesions and reduced late stent thrombosis

sis. Compared to the angiography-guided group, the IVUS-guided group had a significantly lower overall unadjusted ST rate (1.2% vs. 6.9%, P < 0.001), definite ST (0.6% vs. 5.3%, P < 0.001), late ST (0.6% vs. 4.3%, P 5 0.003), MI (4.6% vs. 8.9%, P 5 0.038) and cardiac death (0.9% vs. 3.3%, P 5 0.049). By propensity score matching, 123 paired patients were matched. The late ST at 12-months follow-up was 0% in the IVUS-guided group versus 4.9% in the angiography-guided group (P 5 0.029), resulting in significant differences in ST-elevation MI between the two groups (2.4% vs. 9.8%, P 5 0.030). Conclusions: The IVUS-guided two-stent technique was associated with significantly reduced late stent thrombosis, with a resultant reduction in ST-elevation MI. V C 2012 Wiley
