Retrograde percutaneous recanalization of chronic total occlusion of the left anterior descending artery through an extremely tortuous right ventricular branch.
We report a case of chronic total occlusion (CTO) of the left anterior descending artery, which was treated by percutaneous coronary intervention using a retrograde approach via an extremely tortuous right ventricular branch of the right coronary artery. New concept guidewires and a channel dilator were advanced by delicate manipulation into the distal site of the CTO and a successful percutaneous recanalization was performed. These new concept guidewires may facilitate the retrograde approach for CTOs via tortuous collateral channels.
