Prosthetic Valve Leaflet Perforation resulting in Critical Aortic
Insufficiency: A Rare Late Complication after use of COR-KNOT
Abstract
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 post-implantation) are rare.
Herein, we discuss a patient who underwent remote Trifecta
® (St. Jude, Inc.) surgical aortic valve replacement
(SAVR) presenting with symptomatic critical aortic regurgitation
secondary to leaflet perforation from automatically fastened metallic
Cor-knot ® sutures.
