Lack of Association Between the Outcomes of Aortic Valve Implantation and Edge-to-Edge Repair at US Transcatheter Valve Programs

The association between volume and outcomes of transcatheter aortic valve implantation (TAVI) and transcatheter edge-to-edge repair (TEER) has been extensively studied. 1 Chhatriwalla AK Vemulapalli S Holmes Jr, DR Dai D Li Z Ailawadi G Glower D Kar S Mack MJ Rymer J Kosinski AS Sorajja P Institutional experience with transcatheter mitral valve repair and clinical outcomes: insights from the TVT registry.
