Several studies have demonstrated a relation between left ventricular (LV) dyssynchrony and response to cardiac resynchronization therapy (CRT). Many methods of determining LV dyssynchrony have been proposed, including a value of 65 ms as assessed by tissue Doppler imaging. The aim of the present validation study was to prospectively test the predictive accuracy of the 65-ms cutoff for LV dyssynchrony in a large cohort of patients with heart failure undergoing CRT. The study included 361 patients who had undergone CRT. The clinical and echocardiographic parameters were assessed at baseline and at 6 months of follow-up. The clinical response was defined…
