Doppler echocardiography in the human fetus
Journal of the American Society of Echocardiography, 1988Fetal echocardiography has allowed prenatal diagnosis of heart disease to become a reality over the last decade. Recently, pulsed Doppler flow studies have been applied to the examination of the fetal cardiovascular system. In fetuses with dysrhythmias, complex structural heart malformations, nonimmune hydrops fetalis, or mothers receiving nonsteroidal

Doppler echocardiography in shocked patients
Current Opinion in Critical Care, 2013To reiterate the necessity of integrating echocardiography in the management of shocked patients and to propose a step-by-step functional evaluation of hemodynamics proven to optimize hemodynamic monitoring and to adapt the treatment.Echocardiography has become the cornerstone to hemodynamic monitoring.

Exercise Doppler Echocardiography
Echocardiography, 1987SummaryDoppler echocardiography is a promising technique for evaluating left ventricular performance during exercise. The method is inexpensive and relatively simple to perform and analyze. Studies of reasonable quality can be performed even at high workloads.

Pulsed Doppler echocardiography
1977Cardiac ultrasound has greatly enhanced our ability to define structural disorders in the heart and great vessels. While certain cardiac diseases lend themselves to firm diagnosis by M-mode echocardiography, many valvular and congenital disorders result in normal or nonspecific echocardiographic findings.

Pulsed doppler fetal echocardiography
Journal of Clinical Ultrasound, 1985AbstractPulsed Doppler echocardiography (PDE) has proven value in the examination of the infant or child with known or suspected congenital heart disease. In order to assess how PDE might be useful in the evaluation of the infant in utero, we reviewed our experience with this technique used in combination with both cross‐sectional and M‐mode ...

Stress Doppler echocardiography
1989Perhaps the most serious intervention a cardiologist can recommend to patients under his care is cardiac surgery. Doppler ultrasound has proven merit in identifying patients with critical mitral and aortic stenosis, as well as severe aortic regurgitation who may warrant such intervention [1, 2, 3]. However, the most common complaint that patients bring

Doppler fetal echocardiography in endocardial fibroelastosis
Obstetrics & Gynecology, 2001Endocardial fibroelastosis is a congenital heart disease known to cause congestive heart failure in early infancy. We report a case using new modalities for early prenatal diagnosis of endocardial fibroelastosis causing fetal heart failure.A multipara with two children, who died of endocardial fibroelastosis, was referred for fetal echocardiography at ...

Tissue Doppler echocardiography.
Minerva cardioangiologica, 2010Tissue Doppler echocardiography, since its introduction more than 2 decades ago, had revolutionized echocardiography. In the quest to directly quantify myocardial function, increase sensitivity to detect early subtle myocardial dysfunction and improve ease of use, tissue Doppler echocardiography has evolved from pulsed wave tissue Doppler, to color ...

A Review of Pediatric Doppler Echocardiography
Archives of Pediatrics & Adolescent Medicine, 1984The Doppler principle was described by Christian Doppler in the 19th century.1This principle indicates that motion, under certain circumstances, causes an apparent shift in the frequency of a wave front. To detect this frequency shift, a source of a wave front and a frequency receptor located away from the source are required.

Doppler examination is an integral part of the echocardiogram. Current systems are equipped with spectral Doppler in continuous wave mode (offering measurements of high velocities with limited spatial specificity due to integration of signal along the scan line), pulsed wave mode (high spatial specificity with maximal recordable velocity reduced by the
