Coronary Artery Bypass Grafting in Patients with Severe Calcified Ascending Aorta with Aortic No-touch Technique / 日本心臓血管外科学会雑誌

ABSTRACT

Coronary artery bypass grafting using hypothermic circulatory arrest and ventricular fibrillation without aortic cross clamping in 6 patients with severely calcified aortas is described. The use of hypothermic circulatory arrest or ventricular fibrillation has not been established in coronary artery bypass grafting. We recently used aortic no-touch technique in 6 patients. All patients were supported and cooled with cardiopulmonary bypass, and circulatory arrest was performed in 3 patients. With the exception of one hemodialysis patient, 5 patients survived without neurological deficit. We think the aortic no-touch technique is safe and reliable in coronary artery bypass grafting with severe calcified aortas.
