Abstract Objective: To evaluate cardiac MRI for diagnosis of isolated left ventricular noncompaction(ILVNC). Methods: A total of 8 895 patients underwent echocardiography in our hospital from January to December 2014. Patients suspected to have ILVNC underwent cardiac MRI. Finally, six ILVNC patients were enrolled after a general consideration of manifestations of echocardiography, cardiac MRI and clinical data. Results: The clinical presentations of 6 ILVNC patients were heart failure with left ventricular enlargement. Cardiac MRI showed: two-layered myocardial structure with compacted and thickened noncompacted layer which consisted of trabecular meshing with deep endocardial spaces. The apex was involved in all cases. The intertrabecular recesses were perfused with blood at cardiac MRI end-diastole phase. The maximum end-diastole thickness ratio of noncompacted layer to compacted layer was more than 2.3. Conclusion: Cardiac MRI provides more accurate and reliable evaluation of noncompacted myocardium for ILVNC diagnosis. Further investigation is needed in large group of patients.
