Valvular Regurgitation After Implantation of Prostheses Secured With Cor-Knot Automated Fasteners

Alexander A Brescia et al. Ann Thorac Surg. 2017 Jun.

Abstract

Valvular regurgitation is a recognized complication of aortic and mitral valve procedures, with paravalvular leak the primary mechanism and transvalvular leak less common. The Cor-Knot automated fastener (LSI Solutions, Victor, NY) has been shown to be a safe, viable alternative to knot pushers or manual tying for use in these procedures. Here we present two patients in whom the orientation of the Cor-Knot fastener appeared to result in transvalvular regurgitation necessitating a redo operation. With adjunctive use of Cor-Knot devices, fastener orientation relative to valve geometry must be assessed for optimal results.
