Radionuclide angiocardiographic measurement of left ventricular volume and ejection fraction.
In recent years a number of different radionuclidic techniques have been developed to measure left ventricular volume and ejection fraction. Area-measurement concepts have been applied to static and electrocardiographically gated radionuclidic images which have resulted in accurate measurement of left ventricular end-diastolic volume (LVEDV) and ejection fraction (LVEF). Gated (end-diastolic an...
متن کاملAn angiocardiographic method for directly determining left ventricular stroke volume in man.
• In previous studies from this and other laboratories, rapid biplane angiocardiography has been utilized to quantify left ventricular chamber volume and volume changes in man and experimental animals." Arvidsson measured left ventricular stroke volume in several subjects with valvular heart disease in the course of extensive studies on left atrial volume changes, and Chapman and coworkers' det...
متن کاملLeft ventricular volume in aortic stenosis measured by an angiocardiographic and a thermodilution method.
The action of the left ventricle is impaired in aortic stenosis to a variable degree, and since the extent of myocardial damage will influence the management and prognosis in the individual patient, some way of determining myocardial function is required. For a full assessment of left ventricular performance it is necessary to measure the changes in both volume and pressure throughout the cardi...
متن کاملUltrasound determination of left ventricular position for volume angiography.
The reliability of angiographically determined left ventricular (LV) volume is in part dependent upon the accuracy of the determination of the position of the left ventricular (LV) chamber in rehtion to the x-ray image intensifier. A new device is described which utilizes available ultrasound techniques and equipment to ascertain readily the height of the LV above the table top with the patient...
متن کاملNon-invasive left ventricular volume determination by two-dimensional echocardiography.
Twenty patients undergoing routine left ventricular single-plane angiography have been investigated by an ultrasonic triggered B-scan technique to provide a two-dimensional cross-sectional image of the left ventricle in end-systole end-diastole. An area-length method has been used to establish the correlation between the angiographic and the echocardiographic assessments of left ventricular cha...
