Abstract:: Abstract: Objective To explore the application of ultrasound in the diagnosis of noncompaction of the ventricular myocardium and discuss its clinical value. Methods A total of 45 patients with noncompaction of the ventricular myocardium were selected as study group, and 45 healthy people who underwent a physical examination were selected as control group. The cardiac structure was examined with cardiac color B-mode ultrasonography, and the differences in cardiac indexes between patients with noncompaction of the ventricular myocardium and healthy controls were analyzed. Results The left atrial diameter and left ventricular interior diameter were (40.2±2.1) and (68.3±3.2) mm in study group, which were significantly larger than (28.4±3.2) and (18.3± 3.2) mm in control group (P<0.05). The myocardial thickness and left ventricular ejection fraction in study group were obviously lower than those in control group ［(4.3±0.3) mm vs (9.3±2.3) mm, P<0.05; (45.3±3.5)% vs (64.3±3.2)%, P<0.05］. The left ventricular end-diastolic dimension of study group was (42.3±5.3) mm, significantly longer than (30.4±3.4) mm in control group (P<0.05). Conclusion Using cardiac color B-mode ultrasonography for the diagnosis of noncompaction of the ventricular myocardium which is of high diagnostic value and is conducive to diagnosing cardiac diseases in clinical practice should be further popularized in clinic.
