Building a New Annulus: A Technique for Mitral Valve Replacement in Heavily Calcified Annulus

Long‐term outcome in a case of translocated mitral valve replacement for massive mitral annular calcification

“…Several surgical techniques have been used to manage extensive calcification at the mitral annulus, such as the active removal of calcification and posterior mitral annular reconstruction using an anterior MV patch 4, 5 to create a new annulus 6, 7, or a combination of these techniques 2. Complete calcium debridement may cause atrioventricular rupture, left circumflex coronary artery damage, and/or thromboembolic events 1.…”

Using a double-plicated posterior leaflet as an anchor for mitral valve replacement: a case of mitral annular calcification

“…Many reports have been published on possible solutions such as: suturing the prosthesis to the LA itself [1], developing a collar for the prosthesis [4], using the leaflets to secure the prosthesis [5], plicating both mitral leaflets and the LA to create a new annulus [6], and using a Dacron graft between the LA and the prosthesis.…”

“…By preserving the posterior leaflet, the subvalvular apparatus is also maintained. Our method of suturing the prosthesis to the posterior leaflet is similar to that of Di Stefano et al [6], who plicated the mitral leaflets and the atrial wall to create a new annulus. Although we used only the equine pericardium-covered posterior leaflet as a new annulus, we plicated the leaflet twice.…”

Partial Translocation Mitral Valve Replacement with Autologous Pericardial Patch Reinforcement of Ventricularized Left Atrial Wall for Severe Annular Calcification Extending to the Left Ventricle

“…Various techniques for mitral prosthesis implantation have been proposed for patients in whom the mitral annulus would not be appropriate for MVR because of MAC . Di Stefano et al reported the technique of creating a new annulus by plication of both mitral leaflets and the atrial wall. Nezic et al described the procedure focusing on partial decalcification of the posterior mitral annulus and its reinforcement and buttressing with the transferred anterior mitral leaflet.…”
