Abstract
We report a rare case of acute type A aortic dissection with aortic regurgitation and coronary malperfusion secondary to intimo-intimal intussusception. A 51-year-old man complaining of back pain was given a diagnosis of acute type A aortic dissection. Intraoperatively, appearance, the whole surface of the intimal flap could be seen at the sinotubular junction. We speculated that the flap in the diastole had prolapsed into the left ventricle through the aortic valve, resulting in aortic regurgitation and coronary malperfusion. In case of acute type A aortic dissection with intimo-intimal intussusceptions surgery should be performed as soon as possible.
