[Acute surgically-treated complications of myocardial infarct. Clinical experience and discussion of surgical indications].

Post-infarction free-wall, papillary muscle and septal myocardium rupture yields a lowering mortality, not only due to the improved surgical technique but also to a more careful selection of surgical candidates. The value of pericardial decompression in cases of free-wall rupture is discussed. Echocardiographic evidence of blood in the pericardium after a myocardial infarction is not a direct indication for a diagnostic sampling, decompression or surgery. Pericardiocentesis is not a risk-free procedure and should be limited to patients with life-threatening acute tamponade. Clinical results of 34 patients operated upon for myocardial rupture, regardless of adopted technique or timing of surgery, confirm that the decision about a patient's operability should follow a careful evaluation of the following risk factors in this order: infarct size, age, cardiogenic shock, multiorgan failure, rupture site, cardiac failure and associated diseases.
