MDCT Derived Left Ventricular Function in Relation to Echocardiography: Validation and Revising the Role with the Evolving Technology.

Background: Coronary computed tomography angiography (CCTA) is a frequently performed examination for coronary artery disease. When performed with retrospective gating, there is an opportunity to derive functional parameters of left ventricle utilizing automated software. Complementary information, if validated with established standards, will enhance the total value of study.
