Left ventricular function by echocardiography correlates poorly with cardiac MRI measures in Duchenne muscular dystrophy

Table 2 Comparison of Echocardiography and CMR measures of LV function

Echocardiographic Measures	Adequate Echocardiographic Image Quality (N = 12)	Correlation	P-value
		CMR LVEF
M-mode FS	12/12 (100%)	0.59¹	0.042
2-Dimensional FS	7/12 (58.3%)	0.79¹	0.033
Biplane LVEF	4/12 (33.3%)	-0.07²	0.531
4 chamber LVEF	7/12 (58.3%)	0.5²	0.09
3-Dimensional LVEF	5/12 (41.7%)	0.28²	0.168
Subjective global function	12/12 (100%)	0.08³	0.35
		CMR ε_cc
ε_cc	8/12 (66.6%)	0.52¹	0.045
