Cross sectional early mitral flow velocity profiles from colour Doppler.
Instantaneous cross sectional flow velocity profiles from early mitral flow in 10 healthy men were constructed by time interpolation of the velocity data from each point in sequentially delayed two dimensional digital Doppler ultrasound maps. This interpolation allows correction of the artificially produced skewness of velocities across the flow sector caused by the time taken to scan the flow ...
متن کاملCross-sectional early mitral flow-velocity profiles from color Doppler in patients with mitral valve disease.
BACKGROUND Cross-sectional flow-velocity profiles from early mitral flow in 20 patients (10 with mitral regurgitation and 10 with mitral stenosis) were constructed from the velocity data from each point in sequentially delayed two-dimensional digital Doppler ultrasound maps. METHODS AND RESULTS The data suggested that the early mitral flow studied in an apical four-chamber view was variably s...
متن کاملTwo-dimensional mitral flow velocity profiles in pig models using epicardial Doppler echocardiography.
OBJECTIVES This study investigated the velocity distribution across the natural mitral valve. BACKGROUND Information about the blood velocity distribution across the mitral valve is of interest in basic fluid dynamic studies of the natural mitral valve and is needed for precise cardiac output estimates by Doppler echocardiography. METHODS The velocity distribution across the mitral valve wa...
متن کاملDiagnosis of double aortic arch by cross sectional echocardiography with Doppler colour flow mapping.
A case of double aortic arch in a 15 month old boy was diagnosed by cross sectional echocardiography supplemented by Doppler colour flow mapping. These examinations showed two very large vessels communicating with the aorta; the demonstration of anterograde flow in one vessel and retrograde flow in the other enabled a definite diagnosis of Edwards type IA double aortic arch to be made.
متن کاملVelocity profiles in mitral blood flow based on three-dimensional freehand colour flow imaging acquired at high frame rate.
AIMS To describe the mitral blood flow velocity distribution, we applied a freehand dynamic three-dimensional (3D) colour flow method using a moving sample surface that followed the mitral apparatus during diastole. METHODS Nineteen healthy volunteers were studied. The ultrasound data were captured from 10-20 heartbeats at high frame rate (mean 46 frames/s) while freely tilting the transducer...
