Long-Sheath Assisted Transcatheter Aortic Valve Replacement: The Best and Worst Cases.

Transfemoral transcatheter aortic valve replacement (TAVR) is quite challenging in patients with tortuous aorta. Recently, the combined method of buddy wire and long-sheath use was reported. We describe 2 cases having tortuous aorta undergoing transfemoral TAVR following opposite clinical courses. A long-sheath supported transfemoral approach is an effective method in patients with tortuous aorta; however, the tip of a large-bore sheath could cause an aortic injury during the procedure. The advantage of the transfemoral approach and risk of aortic injury should be counterbalanced, especially in patients with fragile tortuous aorta.
