40 year male with abnormal echo findings, concern for noncompaction. MRI ordered for further evaluation. Left VentricleThe left ventricle is mildly dilated with decreased systolic function. The overall LV ejection fraction is 48%. The LVEDV is 246 ml (normal range 142+/-34), the LV end diastolic volume index is 119 ml/m2 (normal range: 74+/-15), the LVESV is 129 ml (normal range 47+/-19) and the LV end systolic volume index is 63 ml/m2 (normal range 25+/-9). There are no regional wall motion abnormalities present. There is no late gadolinium enhancement to suggest the presence of an underlying fibrosing, infiltrative, or inflammatory process. There are findings consistent with ventricular noncompaction, focused in the apical ventricular myocardium as well as the mid-distal lateral wall. Native myocardial T1 values are normal (1055 msec). No evidence of iron overload.Left AtriumThe left atrium is normal in size. Right VentricleThe right ventricle is mildly dilated with decreased systolic function. The overall RV ejection fraction is 39%. The RVEDV is 204 ml (normal range 142+/-31), RV end diastolic volume index is 99 ml/m2 (normal range 82+/-16), the RVESV is 125 ml (normal range 54+/-17), and the RV end systolic volume index is 60 ml/m2 (normal range 31+/-9). Right AtriumThe right atrium is normal in size.Aortic ValveThe aortic valve is trileaflet, opens widely and there is no significant aortic regurgitation.Mitral ValveThe mitral valve opens widely and there is no significant mitral regurgitation.Pulmonic ValveThe pulmonic valve opens widely. There is no significant pulmonic regurgitation.Tricuspid ValveThe tricuspid valve opens widely. There is no significant tricuspid regurgitation.AortaThere is a left sided aortic arch with a normal brachiocephalic branching pattern. The aortic root is normal in size.Pulmonary VeinsAll four pulmonary veins drain normally into the left atrium.Pulmonary ArteryThe main pulmonary artery is normal in size.Venous AnatomyThe SVC and IVC drain normally into the right atrium.PericardiumThere is no obvious pericardial disease.Extracardiac FindingsThere is a non-specific patchy interstitial abnormality, isolated to the bilateral lung bases of unclear significance. This study is not designed for the specific evaluation of extra-cardiac findings; therefore, the differentiation between artifacts and real extracardiac pathology may be difficult. If clinically indicated, a separate dedicated evaluation should be considered.
1. Left ventricle is mildly dilated with decreased systolic function. The overall LV ejection fraction is 48%.2. Right ventricle is mildly dilated with decreased systolic function. The overall RV ejection fraction is 39%.3. Findings consistent with ventricular noncompaction in a limited pattern present in the apical and mid-distal lateral region of the left ventricular myocardium. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
