ABSTRACT
Objective@#To explore the clinical value of echocardiography in differential diagnosis of segmental wall motion abnormalities in coronary heart disease(CHD), and to provide help for clinical treatment.@*Methods@#From January 2017 to November 2018, 56 patients with segmental abnormal wall motion of CHD in Yuyao People's Hospital of Zhejiang Province were selected in the study.All patients were diagnosed by echocardiography and coronary angiography.The diagnostic coincidence rate, specificity, sensitivity, false negative rate, false positive rate and accuracy of echocardiography were evaluated.@*Results@#Coronary angiography showed abnormal segmental wall motion in 56 patients, with 100.00% anastomosis rate.Echocardiography revealed abnormal segmental wall motion in 54 patients with CHD, 2 patients showed normal segmental wall motion, anastomosis rate was 96.43%.There was no statistically significant difference between the two diagnostic methods(χ2=0.635, P=0.152), but the specificity of ultrasound diagnosis(80.36%), sensitivity(78.57%) and accuracy(80.36%) were lower than those of coronary angiography(100.00%, 98.21%, 100.00%), there were statistically significant differences (χ2=4.173, P=0.034; χ2=5.154, P=0.024; χ2=4.173, P=0.034).@*Conclusion@#Cardiac echocardiography has a high diagnostic value in differential diagnosis of segmental wall motion abnormalities in CHD.It can guide the clinical treatment of these patients to formulate a reasonable treatment plan.Moreover, it is easy to operate, with low cost and more acceptable to patients.

ABSTRACT
Objective To observe the incidence and the rate of embolism in patients undergoing hysteroscopy procedures by using the transesophageal echocardiography (TEE), as well as the changes of respiratoric and haemodynamic variables. Methods Fourty ASA Ⅰ~Ⅱ patients undergoing hysteroscopy procedures under general anesthesia received intraoperative TEE monitoring. The systolic pulmonary artery pressure, the incidence of the venous gas embolism (VGE) and the eegmental wall motion abnormality (SWMAs) were observed. Results In the 40 patients, 38 patients received intravenous anesthesia hysteroscopic surgery, with the intraoperative TEE to monitor the intracardiac VGE. The degree of gas embolism was related with the perfusion and the usage of monopolar or bipolar diathermia (P<0.05). The systolic pulmonary artery pressure promoted and SWMAs were also observed. Conclusions The continue TEE monitor during hysteroscopy could detect the intracardiac gas embolism in time , contributing to early diagnosis and avoiding the occurrence of malignant arrhythmias or myocardial ischemic events.
