SURGICAL TREATMENT OF MITRAL REGURGITATION (MR) COMPLICATING MYOCARDIAL INFARCTION (MI)

Since 1979 until March 1986 eleven patients with MR were surgically treated. Three of these required emergency surgery at the acute stage ; because of ruptured papillary muscle in one and of MR combined with ventricular septal perforation (VSP) in the remaining patients. Only one of the three survived following mitral annuloplasty (MAP), apical amputation and aorto-coronary bypass grafting. Eight patients with papillary muscle dysfunction underwent elective surgery ; MAP was performed in one and mitral valve replacement (MVR) was done in six patients. One of the eight did not have any types of repair on MR. There was no operative death but late death caused by heart failure occurred in three patients including one in the group of MVR and two with residual MR (no repair case and MAP). According to these experiences, in the patients of post-infarction MR leading to intractable congestive heart failure left ventricular function did not always improve as expected, even after successful surgery. Thus in patients with MR complicating MI, MVR should be performed prior to the development of heart failure.
