Coronary angioplasty of a posterolateral branch with severe proximal vessel tortuosity.
We present a case of a patient who experienced recurrent angina 15 months after coronary bypass surgery. A single lesion distal to a graft anastomosis was identified in the posterolateral coronary artery. There were two severe angulations, each greater than 90 degrees proximal to the lesion, with access possible only through the saphenous vein graft to the posterior descending artery. For ultimate success, such challenging anatomy required a combination of an array of guidewires, secondary support catheters, and a deflecting balloon.
