Key result
A buddy balloon technique from the contralateral femoral artery facilitates crossing the native aortic valve during TAVI in cases of extreme calcification or tortuosity.
Why the study?
Does the buddy balloon technique facilitate successful crossing of the native aortic valve during TAVI in cases of extreme calcification or tortuosity?
Does the buddy balloon technique facilitate successful crossing of the native aortic valve during TAVI in cases of extreme calcification or tortuosity?
The buddy balloon technique offers a practical solution for overcoming delivery system hang-ups during TAVI in patients with severe calcification or tortuosity.
May aid complex TAVR delivery; leaves open outcome benefits pending prospective validation.
Percutaneous transfemoral aortic valve replacement is a new rapidly evolving technique that has made significant progress in recent years. The technology is however limitted and in some cases has resulted in failure to deliver the prosthetic valve. We describe a new technique using a buddy balloon, from the contralateral femoral artery, to assist in crossing the native aortic valve in those cases where extreme calcification and or tortuosity have caused the delivery system to hang up on the aortic wall. The technique is easily applied and facilitates the success of the procedure in cases which may otherwise have to be converted to open surgical aortic valve replacement.

Balkin et al. (2010) studied Extreme calcification or tortuosity during percutaneous transfemoral aortic valve replacement. Buddy balloon technique from the contralateral femoral artery was evaluated.
