title: The "Proxis-Tornus" technique for a difficult-to-cross calcified saphenous vein graft lesion.
abstract: Severely calcified lesions may occasionally be difficult to cross. We report a case of emergency percutaneous coronary intervention of a calcified saphenous vein graft lesion. We were unable to cross the lesion with a balloon despite using a 7 Fr guiding catheter, a buddy wire and the Tornus catheter, which was likely due to poor guide support. We describe successful crossing and treatment of the lesion by simultaneously using the Proxis proximal occlusion embolic protection device and the Tornus catheter.
