An 83-year-old man with a previous mitral valve repair using a semi-rigid annuloplasty ring was found to have severe mitral stenosis. A transcatheter approach for mitral valve-in-ring replacement was selected due to the patient’s high surgical risk. Pre-procedural computed tomography scans for transcatheter valve size selection were inconsistent with previously published recommendations. To determine the appropriate valve size, a 25 mm compliant balloon was inflated intraoperatively within the stenotic mitral ring, but yielded no resistance to movement and no ‘waist’. Thus, a 29 mm balloon-expandable prosthetic valve was selected and deployed with no paravalvular leak. This novel balloon sizing technique helped lead to a successful outcome in this case.


 

Video 1: Angiographic video displaying mitral valve-in-ring balloon sizing technique. The 25 mm compliant balloon was inflated within a stenotic mitral ring to determine which prosthetic transcatheter valve size was appropriate. As shown, this technique yielded no ‘waist’ and no resistance to movement, suggesting that a 29 mm valve was necessary.
