Background:
Conventional two‐dimensional angiography lacks the ability to properly image the true bifurcation geometry, and its percutaneous coronary intervention‐induced changes in the clinical setting.
Methods and Results:
A novel three‐dimensional reconstruction system was investigated by retrospectively analyzing 39 lesions in 35 consecutive patients with coronary bifurcation disease treated with the mini‐crush technique. At baseline, significant correlations were proved between two‐ and three‐dimensional systems in terms of either reference vessel diameter (R2= 0.68 and 0.29 for main and side branches, respectively), minimum lumen diameter (R2= 0.73 and 0.36), stenosis diameter (R2= 0.69 and 0.29), and lesion length (R2= 0.48 and 0.58). These results were consistent with those observed after the procedure and at 8‐month follow‐up. Lesion length was significantly longer with the three‐dimensional compared to the two‐dimensional system for both main and side branches (P < 0.001, and P = 0.007, respectively).
Conclusions:
The three‐dimensional quantitative reconstruction system may provide accurate evaluation of the complex curvilinear structure of bifurcation lesions when using a double stent technique. (J Interven Cardiol 2010;23:46–53)
