ABSTRACT
Acute aortic dissection complicated with acute myocardial infarction in a case of 61-year-old woman with an aberrant right coronary artery was successfully treated by emergency operation fore type A acute aortic dissection. However, cardiogenic shock and bradycardia occurred after induction of anesthesia due to right ventricle myocardial ischemia. Cardiopulmonary bypass was established quickly and deep hypothermia was induced. We also perfused the right coronary artery with an external shunt tube to prevent the progression of the right ventricular infarction. The right coronary artery, which originated above the left coronary sinus, was dissected totally. We performed ascending and aortic arch replacement and coronary artery bypass grafting with a saphenous vein graft to the right coronary artery under hypothermic circulatory arrest. She had no major reduction of cardiac function. Although it was a rare combination, aberrant right coronary artery was vulnerable to myocardial ischemia associated with acute type A dissection. The external coronary shunt tube was useful for this type of myocardial ischemia.
