Figure 1: A typical bifurcated lesion with a highly angulated side branch in which the DLC-facilitated reverse wire technique is indispensable for guidewire insertion. (a) Initial angiography. (b) Schema of the bifurcation and the guidewire position during the DLC-facilitated reverse wire technique. (c) Actual guidewire image during the DLC-facilitated reverse wire technique. (d) Final angiography showed a favorable vessel dilation and blood flow. DLC: Dual-lumen catheter
