Differentiation of patients with two-dimensional echocardiography false positive non-compaction of ventricular myocardium by contrast echocardiography.

In this study, the endocardium may be clearly visualized by contrast echocardiography to improve the diagnostic accuracy of patients with noncompaction of the ventricular myocardium. Twenty-four patients (n = 24) suspected with non-compaction of the ventricular myocardium Underwent transthoracic echocardiography including an intracardiac contrast echocardiography. The clinical data, Left ventricular opacification, and contrast echocardiography results were analyzed retrospectively. Twenty-four patients (n = 24) suspected with non-compaction of the ventricular myocardium were classified with transthoracic echocardiography and contrast echocardiography results into two groups: false positive and true positive. There were no significant differences in age, predisposing segments, Left Ventricular End-Diastolic Diameter, Left Ventricular End-Diastolic Volume, Left Ventricular End-Systolic Diameter, Left Ventricular End-Systolic Volume and ejection fraction between the two groups (P>0.05). The thickness ratio of noncompacted to compacted myocardium (N/C) in the true positive group was significantly higher than that in the false positive group (3.47 ± 1.31 vs. 4.96 ± 1.28; P<0.05). The range of noncompact myocardium in non-compaction of the ventricular myocardium patients can be observed clearly by Left ventricular opacification. Contrast medium in trabecular space and crypt is plentiful and ultrasonic contrast is more objective in measuring the thickness of dense myocardium...
