Abstract

Abstract: This study explored the application value of right heart contrast echocardiography combined with transesophageal ultrasound in the diagnosis of cryptic stroke in young and middle-aged patients. 240 young patients with suspected cryptic stroke were selected as the research objects. All patients were examined by right heart contrast echocardiography and transesophageal ultrasound to determine whether there was a right-to-left shunt. Then measured the size of the shunt, and graded it according to the shunt flow. The detection rate of right heart contrast echocardiography combined with transesophageal ultrasound was significantly higher than that of right heart contrast echocardiography and transesophageal ultrasound alone (P<0.05). The sensitivity, accuracy and specificity of right heart contrast echocardiography combined with transesophageal ultrasound in the diagnosis of cryptic stroke in young and middle-aged patients were 91.61%, 87.08% and 80.41%, respectively. The right heart contrast echocardiography combined with transesophageal ultrasound examination can effectively improve the diagnostic sensitivity and accuracy of cryptic stroke screening in young and middle-aged people.

Key words: right heart contrast echocardiography, transesophageal ultrasound, young and middle-aged people, cryptogenic stroke
