OBJECTIVE: The purpose of this study is to describe morphologic features and delayed contrast-enhancement pattern of the noncompaction of the left ventricle in cardiac magnetic resonance (MR) imaging. METHODS: We retrospectively reviewed morphological cardiac MR imaging findings of ventricular noncompaction in 15 patients (eight men, seven women, and ages 6 months to 73 years old, mean 22 year). In 10 patients delayed contrast enhanced images were obtained after the morphological examination. RESULTS: In all patients, noncompaction was seen in the apical and midventricular-lateral segment. Basal-septal segment involvement was not determined in any patients. Noncompacted/compacted ratio was 2-4.5 (mean 3). In nine patients, right ventricular involvement was observed in addition to left ventricular noncompaction. Delayed contrast-enhancement was seen in eight out of 10 patients not only involved segments but also normal segments of the heart. CONCLUSION: Cardiac MR imaging is a valuable imaging method in patients with suspected ventricular noncompaction by showing increased trabeculations, deep intertrabecular recesses and fibrosis. Fibrosis is a common finding in ventricular noncompaction. Copyright (c) 2010 Elsevier Ireland Ltd. All rights reserved.
