Key result
A patient developed rare late leaflet perforation and critical aortic regurgitation more than 5 years after surgical aortic valve replacement using automatically fastened metallic Cor-knot sutures.
Why the study?
Late manifestations of leaflet perforation more than 5 years after the use of automatic fasteners such as Cor-knot are rare.
Case Report (n=1)
Highlights a rare late complication of leaflet perforation and critical aortic insufficiency associated with the use of Cor-knot automatic fasteners in surgical aortic valve replacement.
Late leaflet perforation can occur >5 years after Trifecta AVR; leaves open need for extended durability surveillance.
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.

Patel et al. (2022) conducted a case report in Critical aortic regurgitation secondary to leaflet perforation (n=1). Cor-knot® device was evaluated on Leaflet perforation and critical aortic insufficiency. A patient developed rare late leaflet perforation and critical aortic regurgitation more than 5 years after surgical aortic valve replacement using automatically fastened metallic Cor-knot sutures.
