Abstract
We report a case of percutaneous coronary intervention in a bifurcation lesion involving the left anterior descending artery and the first-diagonal branch. The lesion was calcified with vessel tortuosity. Despite adequate lesion preparation using scoring balloon, the stent was not deliverable, even with deep intubation of 7Fr-guiding catheter. The use of 6-in-7 guiding extension catheter would have required removal of wire from the diagonal branch. To avoid this situation, we down-sized the extension catheter to 5Fr, which was successful in delivering the stent without removal of the wire from diagonal branch. We have also demonstrated this novel technique on ex vivo bench testing.
