Abstract:
Objective To analyze the echocardiographic standardized myocardial segmentation features in patients with left ventricular noncompaction ( LVNC ). Methods Echocardiographic characteristics of 9 patients with LVNC were analyzed and the localization of lesions were determined according to the standardized myocardial segmentation (SMS) recommended by American Heart Association (AHA). Results Loose trabeculation in the myocardial lesions were evidenced in all LVNC patients. Communication between deep intertrabecular recess and LV cavity was evident with color flow imaging. According to SMS of AHA, noncompaction of ventricular myocardium was localized in apical segment in all 9 patients, in apical segment of the inferior wall (IW) in 9 patients, in apical segment of the lateral wall (LW) in 7 patients, in middle segment (MS) of IW in 7 patients, in MS of LW in 6 patients. One NC segment was also evidenced in apical segment and MS of septal ventricular wall, basal segment of IW and LW and right ventricular apex, respectively. NC was not found in left ventricular anterior wall. Conclusion Echocardiographic standardized myocardial segmentation is helpful to diagnose LVNC and NC was mostly localized in the apical segments of LVNC patients.
