Abstract

Results of coronary bifurcation stenting guided by intravascular diagnostic tools were searched. 85 patients took part in the study, there were generated two groups. In the research group intravascular ultrasound of main vessel has revealed stent malapposition in 97.6%. Fractional flow reserve of jailed side branch ostium is less then 0.75 in 7.1% only, despite of the average 78 +/- 4% narrowing. Severe cardiac events in research group during long-term clinical follow-up were better in research group: 6.9% vs 32.5% (p < 0.05).
