Can Balloon Aortic Valvuloplasty Help Determine Appropriate Transcatheter Aortic Valve Size? Vasilis C. Babaliaros, David Liff, Edward P. Chen, Jason H. Rogers, Ryan A. Brown, Vinod H. Thourani, Robert A. Guyton, Stamatios Lerakis, Arthur E. Stillman, Paolo Raggi, Jennifer E. Cheesborough, Emir Veladar, Jacob T. Green, Peter C. Block Transcatheter heart valve replacement is an emerging technology used to treat high-risk patients with aortic stenosis. It is conceptually different from surgical aortic valve replacement in that the native valve is not excised but instead serves as the anchor for implanted devices. In addition, an exact method for determining correct valve size is challenging because of the clinician's inability to visualize the valve directly or use valve sizers. Currently, echocardiographic measurement of the aortic annulus is used to select the appropriate transcatheter heart valve size. We investigated whether measuring balloon pressure during intraoperative aortic valvuloplasty could help in sizing the aortic annulus.
