BACKGROUND Coronary artery fistula (CAF) is a rare cardiac anomaly. Application of transthoracic echocardiography (TTE) is not fully illustrated in pediatric period. Meanwhile, the treatment strategy of CAF is still a controversial issue. CASE PRESENTATION Five cases of CAF with different types were presented. We also retrospectively reviewed 32 records(More)
With the remarkable improvements in ultrasound equipment, transabdominal ultrasound after oral administration of an echoic cellulose-based gastric ultrasound contrast agent (TUS-OCCA) has recently been suggested to be effective in initial screening of gastric cancer. The aim of this study was to evaluate the diagnostic value of TUS-OCCA for gastric cancer.(More)
BACKGROUND Left ventricular diastolic function is impaired during pregnancy. However, changes in left atrial (LA) function remain unclear. We aimed to evaluate changes in LA function during pregnancy using two-dimensional speckle tracking echocardiography (2DSTE). METHODS AND RESULTS 50 pregnant and 50 healthy nulliparous (control group) women were(More)
The objectives of this study are to explore the clinical effects of treatment with tirofiban for high-risk non-ST-segment elevation acute coronary syndrome (NSTE ACS) during peri-operative intervention operation period and to improve the level of clinical treatment. Ninety cases of high-risk NSTE ACS patients were randomly selected from January 2011 to(More)
BACKGROUND Left atrial (LA) function plays an important role in the maintenance of cardiac output, however, in patients with constrictive pericarditis (CP), whether pericardial restriction and adhesion can lead to LA dysfunction, and the characteristics of LA function remain unclear. The aim of the study is to compare the left atrial (LA) function of(More)
Backgrounds Myocardial infarction (MI) model of rats is commonly used in cardiovascular research. However, the noninvasive functional evaluation parameters in this model are lack. Echocardiography is an important tool for assessment of cardiac function in clinic. This study is to explore whether changes of the cardiac function after MI of rats could be(More)
