The left heart ear (LAA) thrombus may appear in the case of the stagnation of the left heart room blood flow, especially in the atrocular tremor, which is an important source of heart -based stroke. According to two large -scale forward -looking studies, the esophageal ultrasonic diagram (Tee) is currently considered a gold standard for detecting LAA thrombus. However, Tee is a semi -invasive and time -consuming surgery, and TEE can sometimes cause discomfort and complications. As a result, the cardiac -to -computer fault scan has been widely used for the detection of LAA thrombosis.

Recently, a research article published a research article on Stroke, the authoritative magazine in the field of cardiovascular disease. The researchers conducted a systematic review and furniture analysis to evaluate the accuracy of diagnosis of LAA thrombosis detection compared with Tee.
From January 1977 to February 2021, researchers conducted a comprehensive search of Pubmed, Embase, and COCHRANE Library Database, incorporated into the study of the diagnostic accuracy of LAA thrombosis compared with TEE. The researchers used the dual variable random effect model to calculate the sensitivity, specificity and post -test probability of LAA thrombus. Quality assessment of diagnostic accuracy research-2 tools for quality assessment.
The study included 27 studies, involving 6,960 patients. The overall sensitivity of early imaging studies was 0.95 (95%CI 0.79-0.99) and the specificity was 0.89 (95%CI 0.85-0.92). The probability of positive posture is 19.11%, and the probability of negative posture is 0.16%. The overall sensitivity of delayed imaging research is 0.98 (95%CI is 0.92-1.00) and the specificity is 1.00 (95%CI is 0.98-1.00). The probability of positive posture is 95.76%, and the probability of negative posture is 0.12%. The delayed imaging method has significantly improved the specificity (1.00 vs. 0.89; P <0.05) and positive post -test probability (95.76% vs. 19.11%; P <0.05).

It can be seen that a delayed image of a cardiac computer fault scan is a reliable alternative to Tee. It allows patients and healthcare personnel to avoid excessive Tee examinations.
