Purpose
To compare cardiac magnetic resonance imaging (CMR) with two-dimensional echocardiography (2D ECHO) in the assessment of left ventricle volumes,
mass and EF in patients with ischemic heart disease and severely depressed LV function.
Although CMR Is the state- of- the art technique in the assesment of cardiac function,
its relationship with echocardiography in patients with severe systolic LV dysfunction is not established yet.

Methods and Materials
Material:
67 patients (12 female) with a multi-vessel coronary artery disease and a history of a myocaridal infarction and low EF were referred for CMR and 2DECHO.
The patients’ data are summarized in Figure 1.
The exclusion criteria were arrhythmia and/or contraindications to CMR.
Patients with clinically significant aortic valve disease,
mitral stenosis and non-ischemic mitral regurgitation were excluded from the analysis.
The period of time between CMR and 2DECHO was 5 ± 2 days.
CMR protocol
CMR studies were performed using a 1,0 T...
Results
The mean values of LV volumes ,
EF and mass revealed by CMR and 2D Echo are presented in Figure 1. Both methods confirmed the strong decline in systolic LV function in evaluated group of patients (mean EF in CMR: 23.5%; in 2D Echo 28.8%).
A moderate to strong correlation between the 2DECHO and CMR measurements in the assesment of LV function was revealed: the highest for EDVi (R2 = 0.73) and ESVi (R2 = 0.69) Figure 2, and the lowest for EF (R2 =...
Conclusion
In evaluated population of patients with severe ischemic systolic LV dysfunction moderate to strong correlation between CMR and 2DECHO in the assessment of LV function parameters and mass was revealed.
The between-method agreement strongly depends on the degree of LV dysfunction.
Differences in LV indices are higher in patients with a more severe LV dysfunction.
