Dual Pulsed-Wave Doppler Tracing of Right Ventricular Inflow and Outflow: Single Cardiac Cycle Right Ventricular Tei Index and Evaluation of Right Ventricular Function
BACKGROUND AND OBJECTIVES The reliability and usefulness of the right ventricular (RV) Tei index (RTX) remains controversial because it has not been possible to simultaneously measure RV inflow and outflow. However, dual pulsed-wave Doppler (DPD) enables flow velocities to be obtained at different sampling sites simultaneously. In this study we evaluated the feasibility and reliability of RTX v...
متن کاملTotal right ventricular exclusion improves left ventricular function in patients with end-stage congestive right ventricular failure.
BACKGROUND We developed a total right ventricular (RV) exclusion procedure for the treatment of isolated congestive RV failure. The objective of the present study was to elucidate the effects of a complete removal of RV volume overload (RVVO) on the surgically created single left ventricle (LV). METHODS AND RESULTS Three adults (2 arrhythmogenic RV dysplasia, 1 Ebstein) and 5 children (all Eb...
متن کاملLeft ventricular Tei index in athletes.
I read with great interest the recently published study by Stoylen et al. in the December, 2003, issue of European Journal of Echocardiography. The investigators reported that all intervals of the heart cycle and myocardial performance index (Tei) of left ventricle (LV) were shortened during incremental exercise. We also found that Tei index in athletes was significantly lower than that in the ...
متن کامل[Influence of preload reduction on Tei index and other Doppler echocardiographic parameters of left ventricular function].
OBJECTIVE To assess the influence of preload reduction by hemodialysis on Doppler Tei Index of myocardial performance and other parameters of cardiac function. METHODS The Tei index and left ventricular (LV) systolic and diastolic function parameters were estimated, before and after a single hemodialysis session. Only subjects who were in sinus rhythm, without history of coronary artery disea...
