Variation of Angles Between the Branches of Coronary Bifurcations During Interventional Correction
The aim of the work is to study the effect of interventional correction accompanied by stents implantation on the configuration of bifurcations of coronary arteries.
Materials and Methods. There have been studied the variations of configuration of coronary bifurcations branches in the process of intervention based on the contrast angiography findings in 49 patients (9 women and 40 men) with the involvement of 52 bifurcations of coronary arteries. All the patients have undergone conditional T-stenting. In 36 cases a single-stent correction has been performed, in 16 cases — two-stent correction.
Results. There has not been stated a unique effect of intervention on the configuration of coronary bifurcations both in a single-stent and two-stent correction. In selected cases, when performing interventional correction, an expressed variation in the configuration of bifurcations has been noted. At the same time, comparing mean values of bifurcation angles, no statistically significant effect of correction on the values has been revealed. The angle between a distal segment of the main branch and the lateral branch in patients with two-stent correction has been statistically significantly less than that in patients with a single-stent correction both before and after interventional correction of bifurcations.
