Aortic dissection with diastolic prolapse of intimal flap into left ventricle

Ascending aortic dissection is often a catastrophic condition. Dissection into the commissures or into an aortic valve leaflet may lead to leaflet avulsion and valvular insufficiency due to a flail valve. We present an image report describing an important and life-threatening complication due to the movement of a partially dehisced intimal aortic flap into the left ventricle causing aortic valve insufficiency in a patient with acute dissection of the ascending aorta.
