Background Left ventricular hypertrabeculation (LVHT), also termed noncompaction LVHT, is diagnosed by echocardiography or cardiac magnetic resonance imaging (CMRI), and associated with neuromuscular disorders (NMD). The aim of this study was to assess if LVHT can be diagnosed by CMRI applying echocardiographic definitions. Methods and Results The CMRI images of 19 echocardiographically diagnosed LVHT patients were re‐evaluated (10 female, 14‐67 y of age). Left ventricular hypertrabeculation was diagnosed by CMRI in 9 cases. Patients with CMRI‐diagnosed LVHT were more often females (67% versus 40%), experienced heart failure more often (100% versus 50%), had an LV end diastolic diameter > 57 mm (67% versus 40%), had an LV fractional shortening < 25% (89% versus 40%), and had a larger extension of LVHT than patients without CMRI‐diagnosed LVHT. The prevalence of NMD (87%) did not differ between both groups. Conclusions Echocardiographic definition for CMRI yielded the diagnosis of LVHT in only 47%. When looking for LVHT by CMRI, LV size, function, and extension of LVHT have to be considered. Copyright © 2008 Wiley Periodicals, Inc.
