Retrospectively ECG-gated MDCT coronary angiography is a feasible method for evaluating global left ventricular function, showing good correlation with biplane cineventriculography.
OBJECTIVE: Retrospectively ECG-gated three-dimensional volume data from multidetector CT (MDCT) coronary angiography enable image reconstruction of the cardiac cycle in the diastolic and systolic phases. The objective of our study was to investigate the feasibility of determining left ventricular function from MDCT coronary angiography data sets in 22 patients with coronary artery disease and to study the correlation of MDCT results with those of functional data from biplane cineventriculography. CONCLUSION: Multiplanar reformations from three-dimensional MDCT data allowed good delineation of endocardial and epicardial left ventricular contours. In patients evaluated for coronary artery disease, MDCT coronary angiography with retrospective ECG gating provides functional data in an acceptable correlation (r = 0.8; p < 0.05) to biplane cineventriculography.

Juergens et al. (2002) conducted an observational in coronary artery disease (n=22). MDCT coronary angiography with retrospective ECG gating vs. biplane cineventriculography was evaluated on correlation of MDCT results with functional data from biplane cineventriculography (r = 0.8, p=< 0.05).
