Why the study?

Does transesophageal echocardiography detect potential sources of embolism in patients after stroke and systemic embolic events based on clinical and transthoracic echocardiographic findings?

Population

824 patients after stroke and other suspected systemic embolic events

Comparison

Transesophageal echocardiography (TEE) vs Transthoracic echocardiography and clinical…

Implication

May support TTE triage to limit TEE in sinus-rhythm stroke patients; hypothesis-generating and requires prospective validation.

Structured PICO

Does transesophageal echocardiography detect potential sources of embolism in patients after stroke and systemic embolic events based on clinical and transthoracic echocardiographic findings?

P
Population
824 patients after stroke and other suspected systemic embolic events
I
Intervention
Transesophageal echocardiography (TEE)
C
Comparator
Transthoracic echocardiography (TTE) and clinical rhythm assessment (Group A: sinus rhythm and normal TTE vs Group B: all other patients)
O
Outcome
Detection of potential sources of embolism (left atrial spontaneous contrast, left atrial thrombus, complex aortic atheroma, and interatrial septal anomalies)surrogate

Transesophageal echocardiography has a low yield for detecting major embolic sources in stroke patients who are in sinus rhythm and have a normal transthoracic echocardiogram, suggesting TTE can effectively screen which patients require TEE.
