Asymptomatic long-segmental type A aortic dissection diagnosed by transthoracic echocardiography: A case report and literature review.

Aortic dissection (AD) is a life-threatening disease. Patients usually experience severe pain in the chest, back, or abdomen, but some patients report a variety of other symptoms without pain. Completely asymptomatic AD is sporadic and probably under-recognized. The present study aimed to (a) report an extremely rare case of asymptomatic long-segmental type A AD, wherein exaggeratedly low diastolic blood pressure and broad pulse pressure were the primary signs, and (b) summarize the clinical characteristics of asymptomatic AD through the literature review.
