SURGERY FOR ACUTE MYOCARDIAL INFARCTION

We discuss the current status and outcome of surgery for acute myocardial infarction (AMI). The optimal timing of surgical revascularization following AMI is a matter of controversy. Early surgery after an AMI involves high risk. If elective surgery is possible under mechanical cardiac support, cardiac artery bypass grafting (CABG) can be performed with acceptable mortality rates early after AMI. On-pump beating heart revascularization is efficacious in patients in cardiogenic shock or with unstable hemodynamics early after AMI. For postinfarct ventricular septal perforation, an infarct exclusion technique is a standard surgical procedure. For an oozing-type postinfarction left ventricular free wall rupture, a sutureless technique is effective. For papillary muscle rupture, emergent mitral valve replacement concomitant with CABG is recommended.
