Analysis of left ventricular regional dyssynchrony: comparison between real time 3D echocardiography and tissue Doppler imaging.

Background: There is a paucity of information concerning left ventricular (LV) dyssynchrony assessment by real time three-dimensional (3D) echocardiography (RT3DE) versus tissue Doppler imaging (TDI).

Aims: To compare RT3DE and TDI LV dyssynchrony assessment.

Methods: A prospective study of 92 individuals (56 men, age 47 +/- 10 years), 32 with dilated cardiomyopathy (CMP), and 60 healthy individuals.
