[Left ventricular rupture at an atypical place after mitral valve replacement: a case report]

Left ventricular rupture after mitral valve replacement (MVR) is a relatively rare, but a lethal complication. We report a case with this complication. The case was a 62-year-old woman with MSr, TR, and giant left atrium. She underwent MVR with SJM 29 mm, and TAP. During the operation, we found bleeding in the pericardial cavity, and confirmed left ventricular rupture. The place of the rupture was similar to Type I, but it was not posterior atrioventricular wall, but was lateral wall, left side of LAD. We thought that a manipulation during MVR was relevant to this event. Because, this place was opposite the anterolateral commissure of mitral valve to which the chordae tendineae and papillary muscles were adhered. It appeared that the annulus was injured at this point during the operative procedure.
