MDCT findings of acute aortic dissection with diastolic prolapse of the intimal flap into the left ventricle.

Acute aortic regurgitation is frequently recognised in patients with Stanford Type A aortic dissection. However, diastolic prolapse of the aortic intimal flap into the left ventricle can cause aortic regurgitation in rare cases. Here is presented an image report of severe aortic regurgitation that was secondary to the back-and-forth intimal flap movement of acute Type A aortic dissection by the use of transthoracic echocardiography and multidetector row CT.
