[Progressive mitral regurgitation which is necessitated the mitral valve replacement after partial left...

The patient is 61-year-old woman who underwent partial left ventriculectomy, (Batista procedure) due to dilated cardiomyopathy and multiple thromboembolism. Although postoperative course was uneventful, she has had clinical symptoms of the left heart failure due to the increased mitral valve regurgitation at the early postoperative period, gradually. Even though mitral valve regurgitation was severe, it was not apt to re-dilatate the left ventricular capacity evaluated by echocardiography. She underwent the mitral valve replacement on the 92nd postoperative day, and was once possible for weaning from cardiopulmonary bypass under the support of IABP. However, she died on the 19th postoperative day caused by sepsis. It is important to evaluate the accurate mitral valve regurgitation preoperatively for Batista procedure. Although there was the mild mitral valve regurgitation, it is essential to repair or replace the mitral valve for Batista procedure.
