Does transfemoral TAVI using the "buddy stiff guidewire" technique allow successful implantation in patients with extremely tortuous abdominal aortas?
The "buddy stiff guidewire" technique facilitates successful transfemoral TAVI in patients with extremely tortuous and calcified descending aortas.
May enable TAVI in select high-risk anatomy; hypothesis-generating and requires prospective validation before broader use.
Aortic stenosis is the most common primary valve lesion requiring surgery or, especially for older patients, transcatheter intervention (TAVI). We showcase a successful transfemoral TAVI procedure in a very high-risk patient and an extremely tortuous S-shaped descending aorta, characterized by heavy calcifications and multiple strong resistance points. We demonstrated that transfemoral TAVI using the "buddy stiff guidewire" technique could be a feasible, simple, quick, and easy procedure able to straighten an extremely abdominal aorta tortuosity. With all techniques available and careful pre-procedural planning, and thanks to the flexibility of new generation TAVI delivery systems, it is possible to safely perform the procedure even in the most challenging patients.

Intorcia et al. (2022) conducted a case report in Aortic stenosis (n=1). Transfemoral TAVI using the buddy stiff guidewire technique was evaluated on Procedural success. Transfemoral TAVI using the buddy stiff guidewire technique was successfully performed to straighten an extremely tortuous abdominal aorta in a very high-risk patient.
