“…Similar to DCM, the larger volumetric parameters in LVNC can be caused by the dilation of the ventricle at reduced heart function and might become even more pronounced due to the presence of trabeculae [19]. In contrast to our study, Cheng et al and Donghi et al observed higher volumes and lower EF in a DCM population compared with LVNC; however, the lower LV function in DCM might indicate the differences from our results [20,21].…”

“…The clinical manifestations of ILVNC lack specificity. LV trabeculations are not a specific manifestation of ILVNC and are often confused with transitional trabeculations caused by DCM (14). The present study provides a method to distinguish these 2 conditions based on functional evaluation (i.e., myocardial strain).…”

Background: This study explored the value of myocardial strain in the differential diagnosis of isolated left ventricular myocardial noncompaction (ILVNC) and dilated cardiomyopathy (DCM) using cardiac magnetic resonance (CMR) feature tracking technology. Methods: This retrospective analysis was performed on consecutive patients (25 with ILVNC, 30 with DCM, and 30 healthy controls) presenting to Shanxi Cardiovascular Hospital. All ILVNC patients met echocardiographic and CMR criteria for ventricular non-compaction. All patients with DCM met the 2016 American Heart Association and 2018 Chinese Medical Association Cardiovascular Branch diagnostic criteria. cvi42 software (Circle Cardiovascular Imaging) was used to measure radial, circumferential, and longitudinal strain (LS) globally and in segments of the left ventricle. Analysis of variance was used to compare strains among groups and among different segments within the same group. Receiver operating characteristic (ROC) curves were used to evaluate the diagnostic efficacy of different parameters in ILVNC and DCM.Results: Basal circumferential strain was lower in the DCM than in the ILVNC group (P=0.05). Both median and apical LS were lower in the ILVNC than in DCM group (P=0.02 and P=0.01, respectively).ROC curves showed that apical LS was the most effective in distinguishing ILVNC from DCM [area under the curve (AUC) 0.883; P<0.001; 95% CI: 0.850-0.977]. Comparing strains among different segments within the same group revealed that in DCM, the circumferential and LS of the apex were higher than those of the basal segment, which is consistent with the pattern in healthy controls; however, has no such regular pattern was seen in ILVNC.Conclusions: Myocardial strain parameters are of considerable value in the differential diagnosis of ILVNC and DCM. Differences in patterns between ILVNC and DCM can be sensitively identified, providing more comprehensive information for early clinical diagnosis.

“…The dice coefficient was calculated as a measure of segmentation precision [14]. Its value ranges from 0 to 1, with one being the most accurate measurement result [15]. Except for the excluded number for Article 3 in Figure 2, there is no evident difference in the findings between Articles 2 and 1.…”

The gold standard for diagnosing left ventricular noncompaction evaluated in this article was compared using cardiac magnetic resonance imaging and echocardiography. To generate results, the paper used systematic data analysis techniques such as article screening, data extraction, meta-analysis, and forest plots. Use data gaps exhibited on forest plots to eliminate untrustworthy data, shown here as major gaps with other data, that should be avoided in follow-up investigations. The value of the aforementioned gold standard for diagnosis is as follows. It was discovered that two figures demonstrated the reliability of cMRI, while the other demonstrated that the echocardiograph was more accurate. Two numbers were eliminated because there was no statistically significant difference, and the data p > 0.05. More data integration is still required.
