Abstract
Heart failure (HF), the leading cause of death in the western world, develops when a cardiac injury or insult impairs the ability of the heart to pump blood and maintain tissue perfusion. Cardiac resynchronization therapy (CRT) is a well - established treatment in selected patients with drug-refractory heart failure. In order to improve the response rate of patients treated with CRT, imaging can provide information on mechanical dyssynchrony, viability, and cardiac venous anatomy. Various echocrdiographic methods have been proposed to quantify intra-ventricular dyssynchrony, including M - mode echocardiography and tissue doppler imaging (TDI). Nuclear imaging techniques can also be used for the assessment of mechanical dyssynchrony. Chen and coworkers developed a novel approach for assessing LV dyssynchrony from gated myocardial perfusion SPECT
