Isolated right ventricular myocardial infarction (RVMI) is a very rare complication of ischemic heart disease. Generally it accompanies infero-posterior or antero-septal myocardial infarction cases. Right ventricular myocardial infarction is a strong predictor of acute right ventricular failure, bradyarrythmia, ischemic and mechanical complications and is frequently complicated by cardiogenic shock which often leads to death. Acute right ventricular ischemia (RVI) and RVMI are big problem particularly during and early post-operative cardiosurgery procedures. Atherosclerotic changes and heart blood flow disturbances predispose to RVI or RVMI that occur more often in cardiosurgical patients, especially in early postoperative period. On the other hand early intraoperative diagnosis and longer reperfusion period result in the correction of heart function and better prognosis.
