The reason why QRS duration predicts mortality but echo dyssynchrony does not is that QRS duration is a better measure of the severity of global ventricular dysfunction.

The study failed to show an effect of CRT on peak oxygen consumption in a double-blind study lasting 6 months in patients with echocardiographic dyssynchrony and QRS less than 130ms. The study was underpowered and did not look at long-term outcome. However, CRT improved symptoms regardless of QRS duration. This trial is hard to interpret but provides modest encouragement to the argument that QRS is irrelevant when selecting patients for CRT.
