Key result
Transoesophageal echocardiography revealed pathological cardiac findings in 25% of patients with ischemic stroke and normal TTE, suggesting low relevance in this population.
Why the study?
Does transoesophageal echocardiography provide significant diagnostic yield for cardiac sources of embolization in patients with ischemic stroke, sinus rhythm, and normal left ventricular function?
Population
159 patients with ischemic stroke, sinus rhythm, and normal left ventricular function
Design
Cohort

Does not support routine TEE after normal TTE in sinus-rhythm stroke with preserved LV function; leaves open targeted subgroup evaluation.
Observational (n=159)
Does transoesophageal echocardiography provide significant diagnostic yield for cardiac sources of embolization in patients with ischemic stroke, sinus rhythm, and normal left ventricular function?
Routine transoesophageal echocardiography has low diagnostic relevance in ischemic stroke patients who have sinus rhythm, normal left ventricular function, and a normal transthoracic echocardiogram.
Chlumský et al. (2006) conducted an observational in Ischemic stroke with low risk of embolic etiology (n=159). Transoesophageal echocardiography (TEE) was evaluated on Pathological findings in the heart. Transoesophageal echocardiography revealed pathological cardiac findings in 25% of patients with ischemic stroke and normal TTE, suggesting low relevance in this population.
