A Case of Ascending Aortic Dissection with Severe Aortic Regurgitation Diagnosed by Echocardiography

Aortic dissection refers to the separation of the aorta into a true and false lumen as the medial membrane of the aorta is torn along the long axis due to a high aortic pressure when a minute rupture occurs in the aortic lining. The mortality rate is very high, and aortic dissection occurs 2∼5 times more in men than women. The prevalent age range is 50∼70 years old. In this case, the authors experienced a diagnosis of aortic dissection that occurred in a young woman in her 30s, which does not occur frequently. In the process of tracking severe aortic regurgitation, aortic valve prolapse was initially suspected. We report this case because aortic dissection could be diagnosed by observing the intimal flap of the ascending aorta in the process of confirming this suspected part.
