Background

The SYNTAX II score predicted probability of mortality is a powerful tool to estimate predictions to guide the choice between percutaneous coronary intervention (PCI) and coronary artery bypass graft for patients with multivessel disease. In the modern era of PCI, however,its predictive capacity in patients with left main coronary artery (LMCA)bifurcation stenosis and treated by PCI is unknown. 

Methods

The patients with LMCA bifurcational stenosis who treated were by PCI were prospectively selected and followed-up. SYNTAX IIscore derived probability of mortality and real life observed mortality were calculated for all patients. 

Results

A total of 87 patients with LMCAbifurcational stenosis who were treated by PCI were included (mean age 61±10, male gender 80%). During median follow-up of 25 months (interquartile rage[IQR] 17-31 months), all-cause mortality was occurred for 11 patients (13%).The SYNTAX II score predicted median probability of mortality was significantly higher than real life observed mortality (19% [IQR 16-27] vs. 9% [IQR 5-13%],p<0.001). Mortality rate at 1 and 2 year for patients with LMCAbifurcational stenosis who treated by PCI was 7% (95% CI 1-13%) and 10% (95% CI4-16%), respectively (Figure 1). 

Conclusion

In the modern era of PCI, real life mortalityrate was improved compared to the SYNTAX II score predicted probability ofmortality in patients with LMCA bifurcational stenosis who treated by PCI.
