Key result
The buddy balloon technique using a 7 mm peripheral balloon successfully facilitated the crossing and deployment of a transcatheter aortic valve in a patient with extreme calcification.
Why the study?
Passing a bulky prosthesis through a narrowed, calcified valve can lead to TAVR delivery failure, requiring special techniques in challenging anatomies.

The buddy balloon technique using a low-profile peripheral balloon can facilitate crossing a heavily calcified and horizontal aortic valve during TAVR when standard techniques fail.
Transcatheter aortic valve replacement (TAVR) is a new, rapidly evolving technology used in severe cases of aortic stenosis. Some TAVR procedures have failed to deliver the prosthetic valve due to challenges. In these cases, it is difficult to pass a bulky prosthesis through a narrowed and calcified aortic valve. Special techniques may be needed in these challenging cases. In our case, the extreme calcification and the horizontal aorta caused the delivery system to hang up on the aortic valve. We used a buddy balloon from the contralateral femoral artery to assist in crossing the native aortic valve.

Khan et al. (2022) conducted a case report in Severe aortic stenosis (n=1). Buddy balloon technique during TAVR was evaluated on Successful valve deployment. The buddy balloon technique using a 7 mm peripheral balloon successfully facilitated the crossing and deployment of a transcatheter aortic valve in a patient with extreme calcification.
