Low yield of transthoracic echocardiography for cardiac source of embolism

To test the hypothesis that the yield for a cardiac source of embolism is very low using transthoracic echocardiography, we reviewed the echocardiographic reports of 1,010 consecutive patients with cerebrovascular accidents who had undergone echocardiography to rule out a cardiac source of embolism;...

Description
Summary:To test the hypothesis that the yield for a cardiac source of embolism is very low using transthoracic echocardiography, we reviewed the echocardiographic reports of 1,010 consecutive patients with cerebrovascular accidents who had undergone echocardiography to rule out a cardiac source of embolism; risk factor information was also available in 493 patients. We also used 325 controls who had undergone echocardiography for other reasons during the same period. Each report was examined for the presence of predefined findings depending on their propensity for causing cerebrovascular accidents via an embolic process. The prevalence of a highly probable source of embolism was low in cases (
