Prosthetic valve leaflet perforation resulting in critical aortic insufficiency: A rare late complication after use of Cor‐knot

The implementation of automatic fasteners such as the Cor‐knot® device (LSI Solutions, Inc.) has revolutionized the field of minimally invasive valvular surgery. Nonetheless, paravalvular regurgitation, valvular embolization, and early leaflet perforation are all potential complications which may occur. Late manifestations of leaflet perforation (>5‐year postimplantation) are rare. Herein, we discuss a patient who underwent remote Trifecta® (St. Jude, Inc.) surgical aortic valve replacement presenting with symptomatic critical aortic regurgitation secondary to leaflet perforation from automatically fastened metallic Cor‐knot® sutures.
