The diagnostic yield of transesophageal echocardiography in patients with cryptogenic cerebral ischaemia: a meta-analysis

Popis výsledku v původním jazyce

Background and purposeThe diagnostic utility of transesophageal echocardiography (TEE) in patients with cryptogenic ischaemic stroke (IS) or transient ischaemic attack (TIA) remains controversial. MethodsA systematic review and meta-analysis was performed according to PRISMA guidelines to estimate the pooled prevalence of potential cardioembolic causes detected by TEE in prospective observational studies of cryptogenic IS/TIA. Cardiac conditions causally associated with cerebral ischaemia were considered to be intramural thrombi and intracardiac tumors according to ASCO phenotyping of IS. ResultsThirty-five eligible studies, comprising 5772 patients (mean age 53.6 years, 56.9% men) were identified. The most common TEE finding was ascending aorta and/or aortic arch atheroma [51.2% (27.4%-74.5%)], followed by patent foramen ovale (PFO) [43.2% (36.3%-50.4%)]. Complex aortic plaques and large PFOs were reported in 14% (10.2%-18.9%) and 19.5% (16.6%-22.8%) of TEE evaluations. The prevalence of atrial septal aneurysm was 12.3% (7.9%-18.7%) and was significantly higher in conjunction with PFO presence (risk ratio 2.04, 95% confidence interval 1.63-2.54, P < 0.001). The prevalence of left atrial thrombus [3.0% (1.1%-8.3%)] and spontaneous echo contrast [3.8% (2.3%-6.2%)] was low. The prevalence of intracardiac tumors was extremely uncommon [0.2% (0%-0.7%)]. Significant heterogeneity was identified (I-2 > 60%) in the majority of analyses. Heterogeneity was not affected by cryptogenic stroke definition (TOAST versus alternative criteria). After dichotomizing available studies using a cut-off of 50 years, PFO was significantly (P = 0.001) more prevalent in younger than in older patients. ConclusionRoutine TEE in patients with cryptogenic IS/TIA commonly identifies abnormal findings. However, the prevalence of cardiac conditions considered to be causally associated with cerebral ischaemia (intracardiac thrombi and tumors) is low.
