[A successful surgical repair of acute postinfarction mitral papillary muscle rupture]

We reviewed a case who underwent early operation for acute postinfarction papillary muscle rupture. The patient was a 75-year-old male who was admitted to our hospital with cardiogenic shock required endotracheal intubation and intraaortic balloon support. The period to operation was 6 days from the onset of inferior myocardial infarction, and 2 days from the onset of postinfarction papillary muscle rupture. The posterior papillary muscle of mitral valve was totally ruptured and the mitral valve was replaced with a mechanical prosthesis (SJM 27 mm). Postoperative clinical course was not smooth, but the patient was going well. We believe to get good results for early operations of postinfarction papillary muscle rupture unless operative chances were lost.
