Key result
The visually estimated V-RESOLVE score performed similarly to the QCA-based RESOLVE score for predicting side branch occlusion during bifurcation intervention (c-statistic 0.76 vs 0.77; p=0.74).

Does the visually estimated V-RESOLVE score perform comparably to the QCA-based RESOLVE score in predicting side branch occlusion during coronary bifurcation intervention?
Absolute Event Rate: 0.76% vs 0.77%
p-value: p=0.74
The visually estimated V-RESOLVE score performs comparably to the QCA-based RESOLVE score for predicting side branch occlusion during coronary bifurcation interventions, offering a more practical tool for real-time use.
Dou et al. (2016) conducted an observational in Coronary bifurcation lesions at risk of side branch occlusion (n=1,601). V-RESOLVE score vs. QCA-based RESOLVE score was evaluated on Risk prediction of side branch occlusion (c-statistic) (95% CI 0.71 to 0.80, p=0.74). The visually estimated V-RESOLVE score performed similarly to the QCA-based RESOLVE score for predicting side branch occlusion during bifurcation intervention (c-statistic 0.76 vs 0.77; p=0.74).
