Optimized stent implantation according to intracoronary Doppler-derived parameters

With use of post hoc determined cutoff values of diameter stenosis (11%), coronary flow reserve (CFR, 2.5), and relative CFR (0.89) that were predictive for major adverse cardiac events at 12 months of follow-up, it was shown that in patients with an angiographic optimal result, the incidence of major adverse cardiac events decreased from 14.3% to 0% with an optimal CFR, and from 15.0% to 1.4% with an optimal relative CFR. It is concluded that angiographic optimal stent implantation in conjunction with optimal CFR and/or relative CFR is associated with an excellent clinical outcome
