Main vessel stenting in the «false» bifurcation coronary lesions compromises side branch vessel ostium often. Functional significance of the side vessel ostium narrowing after main vessel stenting was defined in 40 patients with II-III classes of stable angina pectoris with isolated «false» bifurcation coronary lesions by means of a fractional flow reserve (FFR). Average side branch vessel ostium narrowing was 69,8 ± 8,7%, average value of FFR was detected 0,83 ± 0,06. It was noted, that the visual estimation and the quantitative coronary angiography are unreliable methods in assessment of the severity of side branch vessel ostium narrowing. The results of our study demonstrate, that if FFR > 0,75 it is out of any benefit to conduct additional kissing balloon angioplasty of side brahch vessel ostium. Moreover, it was associated with high risk of side branch vessel dissection and ischemic myocardium injury.
