Simultaneous determination of the stroke volume and the left ventricular residual fraction with the fiberoptic- and thermodilution method.

چکیده
Authors' synopsis Simultaneous measurements of the concentration of dye by a fiberoptic catheter and of the temperature by a thermistor catheter were obtained in dogs. No significant diference for cardiac output and stroke uolume was found. The slightly but significant higher residual.fraction by thermodilution than by Jiberoptic technique is caused by cold transfer between irentricular myocardium and caoity. I t becomes evident after the jifth beat.

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 کاملThe use of invasive techniques, angiography and indicator dilution, for quantification of valvular regurgitations.
Angiographic techniques have been used for the quantification of mitral or aortic and rarely tricuspid regurgitation. Mitral or aortic regurgitant volume per beat and the regurgitation fraction (fao and fm, respectively) are obtained from the angiographic determination of total left ventricular stroke volume (TSV) and forward stroke volume (FSV) estimated by a different technique. Although this...
متن کاملPrecision of measurements of right and left ventricular volume by cine computed tomography.
Precise determination of left and right ventricular stroke volumes is limited with conventional imaging techniques. We determined whether right and left ventricular stroke volumes could be precisely measured with cine computed tomography (CT). Cine CT enables simultaneous imaging of the right and left ventricles at an 8 mm slice thickness with a maximal scanning rate of 17 frames/sec (50 msec a...
متن کاملGram-negative Bacteremia Produces Both Severe
A canine sepsis model that simulates the human cardiovascular response to septic shock was produced in 10 conscious unsedated dogs by implanting an Eschichia coli-infected clot into the peritoneum, resulting in bacteremia. By employing serial, simultaneous measurements of radionuclide scan-determined left ventricular (LV) ejection fraction (EF) and thermodilution cardiac index (CI), the end-dia...
متن کاملEstimation of left ventricular residual volume in the dog by a thermodilution method.
• The importance of ventricular volume as one of the determinants of stroke output has led to the development of methods for measuring ventricular volumes in vivo, using either radiographic techniques" or applications of the indicator-dilution principle."TM The latter method requires the rapid injection of an indicator into the ventricle and registration of the resultant time-concentration curv...
