Video 3: If at First You Don`t Succeed, Try, Try Again: A Stepwise Approach to the Non-Dilatable Lesion

Video 3. LAO cranial angiogram demonstrating the severe diagonal lesion (which was notable for the absence of apparent calcification). The native second diagonal branch contained a tubular, non-calcified 99% stenosis in the proximal third of the vessel (Figure 1, Videos 2 and 3). Rather than re-intervene on the 12-year-old vein graft, which was now totally occluded, a decision was made to intervene on the subtotally occluded native diagonal branch.

A 6 French XB 3.5 (Cordis) guiding catheter was used to engage the left coronary artery and anticoagulation was achieved using intravenous bivalirudin. A Runthrough NS (Terumo) guide wire was used to cross the lesion. An Emerge (Boston Scientific) 2.25mm x 15mm compliant balloon was inflated multiple times.
