EchoBridgeMD Evidence Update #2: POCUS Shows Strong Diagnostic Performance for Acute Aortic Dissection

A new systematic review and meta-analysis provides further support for incorporating POCUS into the early evaluation of patients with suspected acute aortic dissection.
Across 11 included studies, bedside ultrasound demonstrated a pooled sensitivity of 86% and specificity of 84%, with diagnostic performance more favorable for Stanford Type A dissection. Visualization of an intimal flap was the most specific finding, while other echocardiographic findings can provide complementary diagnostic information.
These findings reinforce a concept we recently highlighted in our review of the echocardiographic findings of acute Type A aortic dissection: no single echocardiographic finding excludes dissection, but identifying characteristic findings at the bedside can raise diagnostic suspicion and expedite definitive imaging and management.
POCUS should not replace CTA when dissection is suspected—but it may help recognize the diagnosis before the patient ever reaches the scanner.
