Hypereosinophilic Cardiac Involvement Presenting With Left Ventricular Massive Thrombus and Cardioembolic Stroke: A Case Report
Introduction: It is well known that the tendency toward thrombosis is increased in cancer patients. The increase in cancer procoagulant and tissue factor levels, endothelial damage, and stasis due to compression are among the most accused causes of thrombosis in cancer patients. Hypereosinophilia is a rare condition that causes endothelial damage leading to thrombosis. <s...
متن کاملIdentification of ultrasound echoes from the left ventricle by use of intracardiac injections of indocyanine green.
This study was designed to identify the ultrasound echoes originating from the left ventricle. Injections of indocyanine green and saline were made directly in the left ventricular cavity via a cardiac catheter in patients undergoing routine diagnostic cardiac catheterization. The injections produced a cloud of echoes that filled the left ventricular cavity and outlined the left side of the int...
متن کاملNormal Value of Left Ventricular End-Systolic Elastance in Infants and Children
Background: In certain conditions, there is a need for a specific and improved measure of cardiac performance. Routine methods for assessing left ventricular (LV) function are based on image-analysis or right heart monitoring which do not allow evaluation of ventriculo-arterial interaction. Chen et al presented a noninvasive method allowing measurement of end-systolic pressure–volume relation ...

Background: We assessed different systolic cardiac indices to describe left and right ventricular dysfunction in cirrhotic patients before liver transplantation. Methods: In this case-control study, eighty-one consecutive individuals with the confirmed hepatic cirrhosis and candidate for liver transplantation in the Imam Khomeini Hospital between March 2008 and March 2010 were selected. T...
متن کاملHeart stroke volume and cardiac output by four-dimensional ultrasound in normal fetuses.
OBJECTIVE To establish reference intervals for fetal heart stroke volume and cardiac output with gestation. METHODS Fetal heart ventricular volumes were measured using the four-dimensional (4D) spatiotemporal imaging correlation (STIC) ultrasound technique in 140 normal singleton pregnancies at 12-34 weeks' gestation. The Virtual Organ Computer-aided AnaLysis (VOCAL) technique was used to obt...
