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