Statement of Need
Ventricular dyssynchrony may also increase mortality in heart failure patients.
A better understanding of the underlying pathophysiology and severity of left ventricular (LV) dyssynchrony is needed for the identification of suitable candidates for cardiac resynchronization therapy (CRT), which has been used for patients with heart failure and conduction delays.
Echocardiography has been commonly used to assess ventricular dyssynchrony in heart failure, however, there are some limitations regarding the objective and semi-quantitative analyses of LV dyssynchrony.
