Background

The aim of this study was to evaluate intrahospital and long - term outcomes of patients who underwent percutaneous coronary intervention (PCI) for true bifurcation lesions and how often systematic double – stenting technique was used in complex coronary bifurcations.

Methods

Retrospective analysis of the ongoing Coronary Bifurcation Treatment registry in Latvia Centre of Cardiology and follow - up after 1 year. Study population was divided into two groups: provisional single - stenting (1 stent) and systematic double - stenting (2 stent). Analysed were complex coronary bifurcations according to DEFENITION criteria.

Results

A total of 651 patients were included in this study (1 stent - 528 patients, 2 stent – 123 patients. Complications were perforation (1 stent 0 % vs 2 stent 0.8 % (n = 1), p = 0.189), SB occlusion (1 stent 2.8 % (n = 15) vs 2 stent 0.8 % (n = 1), p = 0.330), no reflow phenomenon (1 stent 0.2 % (n = 1) vs 2 stent 0 %, p = 0.629), cardiogenic shock (1 stent 0 % vs 2 stent 0.8 % (n = 1), p = 0.189), periprocedural myocardial infarction (MI) (1 stent 4.0 % (n = 21) vs 2 stent 6.5 % (n = 8), p = 0.223) and intrahospital stent thrombosis (1 stent 0 % vs 2 stent 0.8 % (n = 1), p = 0.189). 1 - year follow - up till now was possible in 486 patients (1 stent - 404 patients, 2 stent - 82 patients). There were cases of death (1 stent 2.4 % (n = 10) vs 2 stent 3.5 % (n = 3), p = 0.472), hospitalization because of MI (1 stent 0.7 % (n = 3) vs 2 stent 0 %, p = 0.435), hospitalization because of stroke (1 stent 0.3 % (n = 1) vs 2 stent 1.2 %, (n = 1),  p = 0.308), target lesion revascularization (1 stent 1.6 % (n = 6) vs 2 stent 1.2 % (n = 1), p = 0.840) and target vessel revascularization (1 stent 3.4 % (n = 13) vs 2 stent 3.8 % (n = 3), p = 0.747). There were no cases of definite late stent thrombosis. 64 cases of complex coronary bifurcations were identified (1 stent 7.0 % (n = 37) vs 2 stent 22.0 % (n = 27), p < 0.001).

Conclusion

Intrahospital and long - term complication rate in the treatment of true coronary bifurcation lesions was low. There were no cases of definite late stent thrombosis. In complex coronary bifurcations preferred was systematic double – stenting technique.
