Alternative methods for the assessment of mechanical dyssynchrony using phase analysis of gated single photon emission computed tomography myocardial perfusion imaging

Measurement of left ventricular (LV) mechanical dyssynchrony from single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) allows optimization of cardiac resynchronization therapy in heart failure patients. We compared the discriminatory ability and reproducibility of a...

Zusammenfassung:Measurement of left ventricular (LV) mechanical dyssynchrony from single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) allows optimization of cardiac resynchronization therapy in heart failure patients. We compared the discriminatory ability and reproducibility of a new software method, Corridor 4DM (4DM) to the established method, Emory Cardiac Toolbox (ECTb) in normals and heart failure patients. LV dyssynchrony was measured in 100 control (Group 1) and 100 patients with LVEF
