The Value of Echocardiography in the Diagnosis of Non-compaction of the Ventricular Myocardium

To analyze the echocardiographic features of non-compaction of the ventricular myocardium (NVM) and evaluate the diagnostic value of echocardiography in NVM. 34 patients with clinically diagnosed cardiac insufficiency and cardiac arrhythmia were examined by multi-slice scan with GE vivid 7 and Philips IE33 color Doppler sonography. The echocardiographic findings were NVM. Echocardiographic features of NVM were summarized and the distribution characteristics of the lesion area were analyzed. It was found that echocardiography in all 34 patients had obvious characteristics. The myocardium at the lesion site was divided into 2 distinct layers. The outer layer was thin and dense, and the inner layer was thicker, consisting of rich trabeculae and deep recesses with different sizes, which tended to occur in the apical and lateral walls. Color Doppler ultrasound can detect blood flow in the recess and interconnect with the heart cavity. 34 patients were involved in varying degrees of valvular regurgitation of mitral, tricuspid and aortic valves. 29 patients had left ventricular dysfunction, 17 patients with complete left bundle branch block, 12 patients with premature ventricular contractions, and 7 patients with atrial fibrillation. To be concluded, NVM has typical echocardiographic features. Echocardiography can be diagnosed without noticeable symptoms, and it is the most convenient method for diagnosis of NVM.
