Clinical Implications of Bifurcation Angles in Left Main Bifurcation Intervention Using a Two-Stent Technique

Figure 3

Receiver operating characteristic curves showing sensitivity of each angle for predicting TLF risk in patients treated with (a) crush and (b) T-stenting technique. An LM-LAD angle of 152° was the best cutoff value for predicting TLF in the crush group. None of the bifurcation angles had a significant cutoff value in the T-stenting group. AUC, area under the curve; BCV, best cutoff value; CI, confidence interval; LAD, left anterior descending artery; LCX, left circumflex artery; LM, left main; TLF, target lesion failure.
