Extremely Rapid Formation of Mitral Valve Ring Abscess in Infective Endocarditis

A patient with infective endocarditis (IE) due to methicillin‐resistant staphylococcus aureus (MRSA) was found to have conversion of the hypoechoic region of the posterior mitral valve ring apparatus into a clearly delineated echolucent space by repeating transthoracic echocardiography at an interval of 1 week. Color Doppler showed features of blood entry into this space. Abscess formation in IE due to MRSA may be quick and repeated echocardiography may help detect the complications of IE. Semiurgent mitral valve plasty was performed for the associated prolapse of the posterior mitral leaflet using a hand‐made, rolled, twisted autologous pericardial ring.
