title: Surgical treatment for complications of acute myocardial infarction.
abstract: OBJECTIVE
  We report the results of surgical repair for postinfarction left ventricular free wall rupture (LVFR) and ventricular septal perforation (VSP) complicating acute myocardial infarction.
  
  
  METHODS
  We experienced 14 LVFRs and 10 VSPs from January 1991 to December 2002. The mean age of patients with LVFR was 74+/-8.1 years. There were 6 oozing cardiac ruptures and 8 blowout cardiac ruptures. An intraaortic balloon pump (IABP) was inserted in 8 patients, and percutaneous cardiopulmonary support (PCPS) was inserted in 5 patients. The mean age of patients with VSP was 72+/-5.1 years. The rupture was located within the anterior septum in 8 patients and within the posterior septum in 2 patients. All patients required IABP, and one of them needed PCPS. We employed a sutureless technique in 8 patients, direct closure in 5 patients, and infarct exclusion in 1 patient with LVFR. Infarct exclusion was conducted in 9 patients, and the da Silva technique was used in 1 patient with VSP.
  
  
  RESULTS
  The patient survival rate of LVFR was 36% (blowout 13%; oozing 67%). Residual shunt occurred in 4 patients with VSP postoperatively. The overall survival rate for VSP was 70%.
  
  
  CONCLUSIONS
  The operative prognosis of blowout cardiac rupture was poor. Good results were obtained with the infarct exclusion technique for patients with VSP. Although some patients had postoperative residual shunts, the infarct exclusion technique was generally a safe and excellent procedure.
