Analysis of Left Ventricular Regional Dyssynchrony: Comparison between Real Time 3D Echocardiography and Tissue Doppler Imaging

Abstract

We observed a good correlation between RT3DE and tissue Doppler LV dyssynchrony assessment in patients with advanced heart failure.

Real‐time three‐dimensional echocardiographic evaluation of left ventricular systolic synchronicity in patients with chronic heart failure: Comparison with tissue doppler imaging

“…As in our study, EF is frequently used to evaluate the consequences of LVDS in patients with CHF of various degrees. In contrast with the results reported by Vieira et al,1 we found that Tmsv12‐SD% and Tmsv12‐D% yielded results similar to TDI in relation to CHF severity when compared with EF. The selection criteria for CRT take into consideration a LV systolic dysfunction with EF ≤ 35%.…”

“…RT‐3DE analysis allows simultaneous display of 16 regional volumetric waveforms, enabling temporal comparisons among segments together with LVSD evaluation 17, 18. Vieira et al1 found a good correlation between RT‐3DE and pulsed‐wave TDI LV dyssynchrony assessment in patients with advanced heart failure. This is in agreement with the correlation we found between RT‐3DE and TDI‐Ts12‐SD.…”

“…Recent advances in real‐time three‐dimensional echocardiography (RT‐3DE) offer the potential to evaluate LVSD by analyzing the time‐volume curves of up to 16 myocardial segments. Nevertheless, until now, very few studies examining its clinical feasibility have been published, and there is a lack of measurement standardization 1, 2. In the present study, we compared RT‐3DE with TDI for the evaluation of left ventricular systolic synchronicity (LVSS).…”

Real Time Three‐Dimensional Echocardiography in Assessment of Left Ventricular Dyssynchrony and Cardiac Resynchronization Therapy

“…[31][32][33][34] Assessment of LV dyssynchrony by RT3DE also correlated well with the histogram bandwidth and SD of phase distribution derived from phase analysis and gated myocardial perfusion single photon emission computed tomography (GMPS), an alternative technique in the evaluation of LV dyssynchrony.

“…12 In addition, 3DE allows evaluation of regional volumes of divided LV segments. However, as described above, the results of PROSPECT trial failed to show apparent benefit of TDI over other conventional echocardiographic measures.…”
