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 involving main vessel and side branch with diameter more or equal 2.5 mm.
Methods
A retrospective analysis of the ongoing Coronary Bifurcation Treatment registry in Latvia Centre of Cardiology (PCI performed from 01.01.2017. to 30.09.2020.) and follow-up after 1 and 3 years. The study population was divided into two groups: provisional single - stenting (1 stent) and systematic double - stenting (2 stents).
Results
A total of 469 patients were included in this study (1 stent - 387 patients, 2 stent - 82 patients. Procedural complications were perforation (1 stent 0 % vs 2 stent 1.2 % (n = 1), p = 0.175), side branch occlusion (1 stent 2.3 % (n = 9) vs 2 stent 1.2 % (n = 1), p = 0.529), no reflow phenomenon (1 stent 0.3 % (n = 1) vs 2 stent 0 %, p = 0.808). Intrahospital complications were cardiogenic shock (1 stent 0 % vs 2 stent 1.2 % (n = 1), p = 0.175), periprocedural myocardial infarction (1 stent 4.1 % (n = 16) vs 2 stent 4.9 % (n = 4), p = 0.764), all cases were NSTEMI. 1-year follow-up till now was possible in 386 patients (1 stent - 325 patients, 2 stent - 61 patients). There were cases of death (1 stent 2.2 % (n = 7) vs 2 stent 3.3 % (n = 2), p = 0.638), hospitalization because of MI (1 stent 0.9 % (n = 3) vs 2 stent 0 % , p = 0.455), target lesion revascularization (1 stent 0.6 % (n = 2) vs 2 stent 0 %, p = 0.534) and target vessel revascularization (TVR) (1 stent 1.8 % (n = 6) vs 2 stent 1.6 % (n = 1), p=0.894). There were no cases of definite late stent thrombosis. 3-year follow-up till now was possible in 100 patients (table).
| Parameter | Total (n = 100) | 1 stent group (n = 87) | 2 stent group (n = 13) | p value |
| Death | 6 % (6) | 4.6 % (4) | 15.4 % (2) | 0.173 |
| MI during follow - up | 1 % (1) | 1.1 % (1) | 0 | 0.713 |
| TVR | 3 % (3) | 2.3 % (2) | 7.7 % (1) | 0.315 |
| Stroke during follow - up | 1 % (1) | 1.1 % (1) | 0 | 0.713 |
| Definite stent thrombosis | 0 | 0 | 0 | - |
Conclusion
Intrahospital and long-term complication rate in the treatment of true coronary bifurcation lesions was low. There were no cases of definite acute or late stent thrombosis.
