Tiara Valve Implantation in a Patient With Previously Implanted Mono-disk Mechanical Aortic Prosthesis


Ferrari, Enrico; Biasco, Luigi; Faletra, Francesco; Cheung, Anson; Moccetti, Marco; Pedrazzini, Giovanni; Demertzis, Stefanos; Moccetti, Tiziano (2018). Tiara Valve Implantation in a Patient With Previously Implanted Mono-disk Mechanical Aortic Prosthesis. Seminars in Thoracic and Cardiovascular Surgery, 30(2):160-163.

Abstract

Transcatheter mitral valve replacement with the Tiara valve can be performed in inoperable patients with severe functional regurgitation. Risk of left ventricular outflow tract obstruction can be prevented using preoperative 3D imaging and 3D-printed models. However, in the case of mono-disk mechanical prostheses previously implanted in aortic position (Bjork-Shiley), there is an additional risk of mechanical interference leading to reduced leaflet motion and aortic valve dysfunction. Hereafter, we describe the case of a patient with a 27-mm mono-disk mechanical aortic valve implanted in 1978, a EuroSCORE II of 18%, and a Society of Thoracic Surgeon score (mortality) of 16% who successfully underwent a transapical Tiara valve implantation.
