19 year old with abnormal echocardiogram, with concern for non-compaction. MRI done for further evaluation. Left VentricleThe left ventricle is normal in size and function. The overall LV ejection fraction is 55%. The LVEDV is 226 ml (normal range 142+/-34), the LV end diastolic volume index is 121 ml/m2 (normal range: 74+/-15), the LVESV is 103 ml (normal range 47+/-19) and the LV end systolic volume index is 55 ml/m2 (normal range 25+/-9). The LV mass is 141 g (normal range 164+/-36) and the LV mass index is 75 g/m2 (normal range 85+/-15). 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 noncompaction in the left ventricle, focused in the left ventricular apical endocardium as well as the anterior mid ventricle. Left AtriumThe left atrium is normal in size. Right VentricleThe right ventricle is normal in size and function. The overall RV ejection fraction is 50%. The RVEDV is 212 ml (normal range 142+/-31), RV end diastolic volume index is 113 ml/m2 (normal range 82+/-16), the RVESV is 107 ml (normal range 54+/-17), and the RV end systolic volume index is 57 ml/m2 (normal range 31+/-9). There are findings consistent with noncompaction, focused on the lateral right ventricular wall. 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 FindingsThis 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 normal in size and function. The overall LV ejection fraction is 55%.2. Right ventricle is normal in size and function. The overall RV ejection fraction is 50%.3. Presence of noncompaction in the left ventricle, focused in the left ventricular apical endocardium as well as the anterior mid ventricle. There is also presence of noncompaction in the right ventricle, focused on the free wall.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
