Key result
Echocardiography diagnoses circumferential Type A aortic dissection causing severe AR and LMCA obstruction.
Why the study?
Circumferential Type A aortic dissection is a rare variant that can cause devastating sequelae, and invasive aortography can be limited in visualizing it, making echocardiography essential.
Case Report (n=1)
Echocardiography is a crucial imaging modality for diagnosing rare circumferential Type A aortic dissections and their complications, such as coronary obstruction and aortic regurgitation.
Alerts clinicians to catastrophic complications in circumferential aortic dissection; leaves open need for larger studies on incidence and management.
Mini‐Abstract Circumferential dissection of the ascending aorta is a rare subtype of Type A aortic dissection which involves the entire intimal layer of the aorta which can cause a variety of devastating sequelae, given its propensity to involve the aortic valve and coronary arteries. Echocardiography is essential in making the diagnosis and visualize its involvement of the cardiovascular system, as invasive aortography can be limited in visualization of this unusual variant of aortic dissection. We present a patient who suffered a circumferential dissection of the ascending aorta which also caused severe aortic regurgitation and ischemia from left main coronary artery obstruction.

Yang et al. (2012) conducted a case report in Circumferential Type A aortic dissection (n=1). Circumferential Type A aortic dissection was evaluated. Circumferential Type A aortic dissection in a single patient caused severe aortic regurgitation and left main coronary artery obstruction, which was diagnosed using echocardiography.
