A Case of Ischemic Cardiomyopathy Complicated by Porcelain Aorta Treated with Dor Operation and CABG Using an Occlusion Balloon / 日本心臓血管外科学会雑誌

ABSTRACT

In patients with so-called porcelain aorta characterized by calcification of the total aorta, manipulation of the ascending aorta can cause cerebral infarction and other conditions due to aortic dissection or rupture and calcified debris. In the present case with ischemic cardiomyopathy and porcelain aorta, an occlusion balloon catheter was inserted into the ascending aorta to avoid its clamping, followed by Dor operation and CABG under cardiac arrest with normothermic extracorporeal circulation. Techniques such as deep hypothermic circulatory arrest and surgery while the heart is beating are often currently used as auxiliary methods to avoid aortic clamp. However, the present case with insufficient left ventricular function required a left ventriculotomy, and thus the technique presented here is useful for shortening the surgical time and ensuring a reliable outcome of the operation.
