TDE parameters documented reduced systolic and diastolic function of both ventricles in obese patients. 2-dimensional speckle tracking analysis revealed that circumferential and radial but not longitudinal strain and SR were impaired in the obese group.

In patients undergoing diagnostic work-up for CAD, the measurement of LVEF by QGS algorithm provides high correlation and satisfactory agreement with the results of reference ultrasound method--3D echocardiography.

The study presents case of a 62-year-old female patient with symptoms of the heart failure NYHA class III intensifying for the last 2 months. Physical examination at admission showed no significant abnormalities. In two-and three-dimensional echocardiography normal thickness and contractility of the left ventricle wall were found, as well as the normal systolic function of the right ventricle. In enlarged right atrium a structure of the oval shape was found with the features of continuity with atrial septum and bulging of a small part of the structure through the orifice of the tricuspid valve to the right ventricle. In the study no features of blocking the tricuspid flow or the inflow from the main veins and coronary sinus were detected. On the basis of the complete echocardiographic examination and clinical presentation, tentative diagnosis of right atrium myxoma was made. Coronary angiography showed no significant abnormalities in coronary arteries. After cardio-surgical consultation the patient was scheduled for surgical removal of the tumor, which was performed without complications. The histopathological examination confirmed the diagnosis of myxoma. In the follow-up echocardiography carried out after 8 months reducted size of the right atrium and a normal function of the ventricles were demonstrated. There were no features of tumor re-growth.
