Key result
Bedside TTE achieves a ~92% detection rate for acute proximal aortic dissection, matching CT.

Bedside transthoracic echocardiography is a highly accurate, rapid first-line imaging modality for diagnosing acute type A aortic dissection and assessing aortic diameter, comparable to computed tomography.
Sobczyk et al. (2015) conducted an observational in Acute proximal aortic dissection (Type A) (n=178). Transthoracic echocardiography (TTE) vs. Computed tomography (CT) was evaluated on Detection of proximal aortic dissection (p=0.000). Bedside transthoracic echocardiography demonstrated a 92.44% detection rate for acute proximal aortic dissection, showing no statistically significant difference compared to computed tomography.
