The accuracy of measurement of the diastolic closure rate of the normal mitral valve has been improved by using strip chart records and by measuring only echograms in which diastolic closure approximates closely to a monophasic form.J C Rodger...
Echocardiography studies of the normal aortic valve and the valve involved by disease were accomplished with pulsed ultrasonic techniques and extended recording by oscilloscope record camera. In aortic stenosis, normal cusp architecture was obscured by a thick multilayered echo pattern usually heavier than...
Clinical and experimental evidence regarding the benefits of preserving the subvalvular apparatus during mitral valve replacement has been debated. Reductions in the left ventricular end-diastolic dimensions have been shown, by echocardi... Shaunak,Shah,Probal,... - 《Indian Journal of Thoracic & Ca...
Maximum LA volume was measured at end-systole, immediately before mitral valve opening and minimum LA volume was measured at end-diastole, immediately before mitral valve closure [17]. Image quality was qualitatively assessed by expert observers as either good, acceptable, or poor with consideration...
In this position, the right and left ventricles were visible in all the camels, the tricuspid valve in 20 and the mitral valve and the right and left atria in 19 camels. Figure 2 Right parasternal caudal long-axis view of the left and right ventricles (four-chamber view). The chordae ...
Mitral valve (MV), septum (S) and posterior LV wall (LVW) motion, can also be obtained and may be of value in the measurement of systolic time intervals (STI) by echograms (E). Thus, we studied a group of 40 normal school children by E to establish normal standards for PEP/EP ...
In a cine acquisition, the maximum volume image can be defined as last image immediately before opening of the mitral valve. Accordingly the minimal LA volume image can be defined as the first image after closure of the mitral valve [36]. Demographic parameters Body surface area (BSA) has ...
Correlates of the Echocardiographic Waves of the Mitral Valve in Normal Subjects of Various Ages A cardiographic study was performed on 71 subjects including 14 children, 42 young and middle-aged adults, and 15 old persons without evidence of heart dis... A.,A.,Luisada,... - 《Journal of...
Table 34 Mitral valve flow for determination of diastolic left ventricular function according to reference [80] Full size table Garcia, et al. [77] and Callaghan, et al. [76] have reported normal thoracic aorta flow parameters using 4D Flow CMR. Amongst other parameters, Garcia obtained measure...
Mitral valve closing force is not diminished in patients with incomplete mitral leaflet closure: Echo-Doppler insights into the mechanism of functional mit... To explore this mechanism, we therefore calculated closing force in 67 patients, 37 with IMLC and 30 with mild MR and no IMLC (normal...
