Truncated semi-major axis is from widest short axis diameter to the mitral annulus plane in the left ventricle at diastole. Epicardial area of the left ventricle, cross section [parasternal short axis view] at the level of the papillary muscles in diastole. Myocardial tissue velocity by Pulsed Wave Doppler, typically adjacent to the mitral annulus, measured in early diastole. Transmitral velocity measured at the leaflet tips at the onset of diastole divided by the myocardial velocity measured at the same point in the cardiac cycle. Correlates with left ventricular filling pressure. Myocardial tissue velocity by Pulsed Wave Doppler, typically adjacent to the mitral annulus, measured at the time of left atrial contraction. Myocardial tissue velocity by Pulsed Wave Doppler, typically adjacent to the mitral annulus, measured during left ventricular systole. The time interval from mitral valve closure to aortic valve opening. Measured as the interval between the mitral valve closing click and the aortic valve opening click on Continuous Wave Doppler. (MCO-ET(Left Ventricle OT))/ET(Left Ventricle OT), where MCO is MV Closure to Opening time and ET is Ejection Time. © 2002-2012 International Health Terminology Standards Development Organisation CVR #: 30363434

(TCO-ET(RVOT))/ET(RVOT), where TCO is TV Closure to Opening time and ET is Ejection Time. Ratio of Aortic Valve Acceleration Time to Aortic Valve Ejection Time Volume of blood contained in the left atrium at end-systole. The time interval from the peak of the transmitral Doppler early filling velocity to the intersection with the Doppler baseline derived from the slope of the transmitral early filling wave. Duration of the transmitral velocity wave during atrial contraction. Formats | 241 Ratio of the Mitral Valve Acceleration Time to the Mitral Valve Deceleration Time. The time interval from the closure of the 1st Doppler spectral taken from the mitral valve to the opening of the 2nd Doppler spectral of the mitral valve. Ratio of Pulmonic Valve Acceleration Time to Pulmonic Valve Ejection Time The time interval from the closure of the 1st Doppler spectral taken from the tricuspid valve to the opening of the 2nd Doppler spectral of the tricuspid valve. © 2002-2012 International Health Terminology Standards Development Organisation CVR #: 30363434
