Balloon Aortic Valvuloplasty During Surgical Aortic Valve Replacement (BAV-SAVR)
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
Prospective, two academic center, non-randomized pilot, acute in-patient study correlating pre-operative imaging studies, intra-operative measurements and intra-operative balloon aortic valvuloplasty (BAV) in patients with degenerative aortic stenosis undergoing surgical aortic valve replacement (SAVR) to understand the requirements (device size and radial strength) of emerging percutaneous heart valve technologies in the treatment of aortic stenosis.
Show the correlation between the size of the aortic annulus measured intra-operatively with surgical rings (gold standard) with other methods of aortic annulus measurement that would not require surgical intervention (CT, TEE, TTE)
