Role of Cardiac Magnetic Resonance in the Diagnosis and Prognosis of Ventricular Noncompaction Cardiomyopathy

Methods: MRI scans of cases of LVNC with isolated left ventricular involvement were reviewed. The number of segments involved by LVNC, LVEF, wall thickness of LVNC-affected segments, cardiac output, and cardiac index were determined. An LVEF value of 30% was accepted as a poor prognosis indicator. Low LVEF and morphology were compared by the Pearson correlation method. Results: In total, 31 cases of LVNC were included. The highest correlation was found between EF and the number of segments affected (r = -0.6). LVEF was inversely correlated with the number of segments affected. Other factors that were significantly associated with low LVEF were the presence of fibrosis, low cardiac output, and low cardiac index.
