Cardiogenic shock after myocardial infarction still carries a high mortality despite use of intraaortic counterpulsation and early surgical revascularization. An experimental canine model of left ventricular exclusion and circulation support was developed by closing the mitral valve and by interposing "in series" a cardiac allograft between pulmonary and systemic circulations. This preparation was able to support the recipient circulation after cardiopulmonary bypass in 25 animals. In 16 dogs the graft sustained life for from 1 to 32 days. It is hypothesized that such left ventricular assistance could be used to maintain the life of patients in cardiogenic shock after myocardial infarction. By providing maximal left ventricular decompression and improvement of the native coronary perfusion, this method may reverse the metabolic imbalance responsible for extension of the infarction, thereby salvaging muscle that is in jeopardy but still viable.
