Novel use of twin-pass catheter in successful recanalization of a chronic coronary total occlusion.
One of the most difficult challenges in interventional cardiology has been in finding the approach to treat chronic total occlusions (CTOs). Here we present a case of recanalization of an angulated, calcified CTO. The lesion presented difficulty due to the lack of guidewire support to facilitate crossing of the CTO. In our case, an uncommon approach using a dual-lumen catheter (Twin-Pass) to support and direct a guidewire was attempted. This resulted in a successful percutaneous revascularization.
