Surgical outcomes of mitral valve replacement with concomitant mitral annular reconstruction

Surgical outcomes of mitral valve replacement with concomitant mitral annular reconstruction INTRODUCTIONPathology involving the mitral annulus, such as an abscess in infective endocarditis (IE), extensive calcification, damage followed by removal of a prosthetic mitral valve, and left ventricular rupture after mitral valve replacement (MVR), require mitral annular reconstruction (MAR) during MVR.

Abstract

INTRODUCTIONPathology involving the mitral annulus, such as an abscess in infective endocarditis (IE), extensive calcification, damage followed by removal of a prosthetic mitral valve, and left ventricular rupture after mitral valve replacement (MVR), require mitral annular reconstruction (MAR) during MVR. Severe IE occurs more frequently in prosthetic mitral valves or mitral annuloplasty rings than in native mitral valves. When the mitral annulus is involved, all of the infected prosthetic material and valvular structures including the annular tissue must be completely removed. Since the myocardium is exposed in the excised area, reconstruction of the mitral annulus is mandatory. Reconstruction of the mitral annulus is commonly performed in adults and children using autologous pericardium or glutaraldehyde‐fixed bovine pericardium. Some reports have described reconstruction using Dacron graft or equine pericardium.Although specialized operative techniques for MAR have been reported, few studies have described the early and late clinical outcomes after MVR with MAR. We have encountered various circumstances in which concomitant reconstruction of the mitral annulus was required with MVR. In this study, we analyzed the surgical outcomes of MVR with concomitant MAR in IE and non‐endocarditis (NE) groups.MATERIALS AND METHODSPatient profilesBetween May 1997 and April 2013, 78 consecutive patients underwent MVR with
