title: Transluminal extraction catheter atherectomy in long saphenous vein grafts.
abstract: Lesions in distal coronary vasculature present unique problems for catheter-based interventions. We report two cases of attempted transluminal extraction catheter (TEC) atherectomy for very distal lesions in long circular saphenous vein grafts. One case succeeded with a simple modification of the TEC device; another failed because of excessive tortuosity in the proximal graft. This experience helps define the potential and limitations of TEC.
