Cardiac resynchronization therapy (CRT) is now a well-recognized therapeutic option for
patients with end-stage heart failure. However, not all patients respond to CRT, and …

The significance of left ventricular (LV) dyssynchrony for the prediction of response to
cardiac resynchronization therapy (CRT) has been demonstrated. Parameters reflecting LV …

Background The purpose of this study was to establish the repeatability of left-ventricular
(LV) dyssynchrony and function parameters measured from serial gated myocardial …

Background Placing the left ventricular (LV) lead in a viable segment with the latest
mechanical activation (vSOLA) may be associated with optimal cardiac resynchronization …

The response to cardiac resynchronization therapy (CRT) varies significantly among
individuals. Preliminary data suggest that the presence of myocardial viability may be …

Purpose To compare left ventricular (LV) dyssynchrony assessment by phase analysis from
gated myocardial perfusion SPECT (GMPS) with LV dyssynchrony assessment by tri-plane …

Background—There are ongoing efforts to optimize patient selection criteria for cardiac
resynchronization therapy (CRT). In this regard, the relationship between acute change in …

BACKGROUND: Using phase analysis of gated single photon emission computed
tomography (SPECT) imaging, we examined the relation between myocardial perfusion …

Cardiac resynchronization therapy (CRT) has shown benefits in patients with severe heart
failure. However, at least 30% of patients selected for CRT by use of traditional criteria (New …

Objectives: The purpose of this study was to compare left ventricular (LV) dyssynchrony
assessment by gated myocardial perfusion single-photon emission computed tomography …
