The study aims to discuss annular repair using the autologous pericardial patch in cases with severe mitral ring calcification and endocarditis during mitral valve replacement. In the study, annular reconstruction was applied, during mitral valve replacement, to 8 patients who had extensive annular calcification or annular destruction due to endocarditis. After annular resection, a two-centimeter wide autologous pericardial patch was sutured continuously to the left ventricular wall close to the posterior annulus. After the valve sutures with pledgets were placed at the back of the pericardial patch, the other edge of the patch was sutured continuously to the left atrial posterior wall. Suturing was complete after the whole annulus was encircled. Thereafter, an appropriately sized mechanical prosthesis valve was used. One patient died postoperatively due to low cardiac output (early mortality 12.5%). Echocardiographical paravalvular leakage was not detected in any of the cases during follow-up. Annular dehiscence and other annular pathologies were also not detected. This reconstructive approach may positively influence mortality and morbidity in cases with complicated mitral pathologies.
