DOPPLER 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 ...
متن کاملPractical Echocardiography and Doppler
Echocardiography is one of the grandest techniques of this century. It does no harm to the patient, it can be repeated many times, it is relatively inexpensive, and the amount of information that we can derive from it is extraordinarily useful to the everyday practice of cardiology. Practical Echocardiography and Doppler is a handsome, clearly written text with good illustrations; however, ther...
متن کاملComparison between M-Mode and Doppler echocardiography in diagnosis
Introduction: Patent ductus arteriosus (PDA) is the persistence of a normal fetal structure between left pulmonary artery and descending aorta. Persistence of this fetal structure beyond 10 days of life is considered abnormal. In this study we compared M-Mode and Doppler echocardiography in diagnosis of PDA in children at Aliasghar Hospital in Zahedan and Children hospital in Bandar Abbas for...
