Brief Summary

Many studies have shown the benefits of cardiac resynchronization therapy (CRT) with biventricular pacing in patients with heart failure with left ventricular dysfunction. CRT restores contraction coordination between different regions of the left ventricle, which yields a significant improvement in LV systolic function, symptoms, exercise tolerance and quality of life. In the longer term, treatment with resynchronization induces a reverse remodeling of the left ventricle and a decrease in mortality and morbidity (hospitalization for heart failure). Nevertheless, even if a majority of patients treated with CRT feel the benefit, some (up to 40% depending on the response criteria of CRT) do not experience significant improvement (nonresponders). Echocardiography and imaging have not so far demonstrated their added value to optimize delivery of CRT. Monocentric promising work on limited numbers of patients, however, were carried out. Meanwhile, equipment for delivering CRT evolves and new probes with four poles stimulation of the left ventricle are now used. The objective of this research is to validate new sequences of ultrasound processing estimating the CRT. These tools are based on usual echocardiographic examination of patients
