Video 7. Repeat angiography after unsuccessful attempts with balloon angioplasty demonstrating impaired distal flow. An Asahi Prowater (Abbott Vascular) guide wire was then placed as a parallel buddy wire and focused force balloon angioplasty was performed (Figure 5, Video 6), but again without successful dilatation of the lesion. A 2.0mm x 10mm AngioSculpt scoring balloon (Spectranetics) was then attempted, but was unable to cross the lesion. Repeat angiography following these maneuvers demonstrated significantly impaired coronary flow (Figure 6, Video 7).
