Quantitative assessment of tricuspid regurgitation using pulsed Doppler echocardiography.
Tricuspid valve regurgitation was assessed quantitatively by measuring blood flow velocity in the vena cava using a pulsed Doppler velocimeter. A non-invasive index of regurgitation was obtained by calculating the ratio between the maximum amplitudes of the systolic and diastolic components of the velocity curves. The index was compared with the angiographic grading of regurgitation in 70 patie...
متن کاملQuantitative evaluation of aortic insufficiency by continuous wave Doppler echocardiography.
To assess the usefulness of continuous wave Doppler echocardiography in the evaluation of aortic insufficiency, the aortic regurgitant flow velocity pattern obtained with continuous wave Doppler examination was compared with the results of aortography and conventional pulsed Doppler techniques in 25 individuals with aortic insufficiency. The diastolic deceleration slope as measured from the con...
متن کاملDOPPLER ECHOCARDIOGRAPHY IN SUBCLINICAL RHEUMATIC VALVULAR REGURGITATION: ALONGTERM STUDY
Doppler echocardiography (DE) is known to be a valuable tool for detecting subclinical forms of valvular regurgitation (VRJ in theacutephase of rheumatic fever (RF). Previous studies have mostly dealt with the acute phase problem with only short-term follow-up. In this study, 24 children between 4-15 years of age (mean age II.X±2.7 years) with RF without clinically diagnosed carditis (most ...
متن کاملDoppler Contrast Echocardiography
The advent and evolution of 2D echocardiography with Doppler gave a new dimension to the evaluation of valvular heart disease (VHD) and noninvasive cardiovascular hemodynamics. Extending from basic M-mode evaluation to the more sophisticated Doppler techniques, the way one looks at the valve anatomy and physiology has changed significantly. Doppler echocardiography has become the everyday tool ...
متن کاملFetal Dual Doppler Echocardiography
Dual Doppler echocardiography is a recently developed technique performed using an instrument with two separate sample gates, allowing simultaneous recording of signals from two locations. We describe the use of dual Doppler echo cardiography to assess fetal cardiac rhythm. Fetal arrhythmias are common and encountered in 1 to 2% pregnancies. They often resolve spontaneously and do not require ...
