Triple wire technique for a bifurcation lesion and a subtotal occlusive lesion.
In a critical distal right coronary artery bifurcation lesion, the proximal course of the posterior descending artery was also subtotally occluded. The posterior descending artery gave rise to a small sidebranch just before the occlusion. In the subsequent revascularization procedure, the bifurcation lesion was double-wired. One wire was placed in the postero-lateral branch, and another wire was intended for placement in the posterior descending artery, but it repeatedly selected the sidebranch despite multiple shapings of the wire tip. While the second wire was deliberately kept in the sidebranch, a third wire was used and crossed the occlusive lesion without much difficulty. The second wire was then withdrawn and the revascularization procedure proceeded in the usual manner. The positioning of the second wire in the sidebranch significantly shortened the procedure.
