Normal pulsed wave Doppler echocardiographic parameters of Turkmen horses of Iran
Turkmen horse is one of the oldest and purest breeds in the world, but there is no information on Doppler echocardiographic parameters in this horse. In the present study, pulsed-wave (PW) Doppler echocardiography was performed on 42 clinically normal 3- to 15-year-old racing Turkmen horses. No cardiac disease was detected with two-dimensional (2-D) real-time, M-mode, and colour flow mapping. D...
متن کاملPulsed Doppler echocardiographic evaluation of valvular regurgitation in patients with mitral valve prolapse: comparison with normal subjects.
Pulsed Doppler echocardiography was used to determine prospectively the prevalence of mitral, aortic, tricuspid and pulmonary regurgitation in 80 consecutive patients with mitral valve prolapse and 85 normal subjects with similar age and sex distribution. Mitral valve prolapse was defined by posterior systolic displacement of the mitral valve on M-mode echocardiography of 3 mm or more (40 patie...
متن کامل[Color Doppler evaluation of valvular regurgitation in normal subjects].
430 apparently healthy subjects were studied with color Doppler flow imaging system. There were 216 females and 214 males, their age ranged from 4-80 years (mean 41.2 years). They were divided into 6 groups by every ten years of age, with group I having age below 19 and group VI age above 70. None of the subjects had previous diagnosis of cardiovascular diseases. Mitral regurgitation was detect...
متن کاملColor Doppler Evaluation of Valvular Regurgitation in Normal Subjects
To determine prospectively the prevalence of mitral, aortic, tricuspid, and pulmonary regurgitation in normal persons, 211 consecutive, apparently healthy volunteers were examined with a color Doppler flow imaging system. The subjects were divided into five age groups (group 1, 6-9 years old; group 2, 10-19 years old, group 3, 20-29 years old, group 4, 30-39 years old, and group 5, 40-49 years ...
متن کاملContinuous - wave Doppler echocardiographic detection of pulmonary regurgitation and its
Continuous-wave Doppler echocardiography was used to estimate pulmonary artery pressures by measuring pulmonary regurgitant flow velocity in 21 patients with pulmonary hypertension (mean pulmonary artery pressure 20 mm Hg) and 24 patients without pulmonary hypertension. The pulmonary regurgitant flow velocity patterns, characterized by a rapid rise in flow velocity immediately after closure of ...
