Abstract
Based on the results of the present study, we concluded that:
• Left ventricular mechanical dyssynchrony frequently occurred in patients with left ventricular systolic dysfunction in a prevalence of 77%.
• The presence of large perfusion defect, reduced EF and LBBB were the independent predictors of left ventricular mechanical dyssynchrony in patients with left ventricular systolic dysfunction.
• The presence of residual viable myocardium is associated with more LV synchrony.
• Evaluation of scar tissue and viable myocardium may be considered in detection of the degree of LVMD.
• The etiology of cardiomyopathy may affect the degree of LVMD.
• Not all dyssynchronic hearts are CRT responders as the prevalence of SD≥43 was only 20%.
