60 year old male with non ischemic dilated cardiomyopathy with suspected LV non compaction (from outside hospital imaging), recurrent atrial fibrillation. MRI for assessment of possible LV non compaction. Left VentricleThe left ventricle is severely dilated with globally severely reduced systolic function. The overall LV ejection fraction is 19%. The LVEDV is 421 ml (normal range 142+/-34), the LV end diastolic volume index is 204 ml/m2 (normal range: 74+/-15), the LVESV is 339 ml (normal range 47+/-19) and the LV end systolic volume index is 164 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 is no LV thrombus. LV morphology has the appearance of LV non-compaction.Left AtriumThe left atrium is severely dilated. Right VentricleThe right ventricle is normal sized with mildly reduced systolic function. The overall RV ejection fraction is 45%. The RVEDV is 150 ml (normal range 142+/-31), RV end diastolic volume index is 72 ml/m2 (normal range 82+/-16), the RVESV is 78 ml (normal range 54+/-17), and the RV end systolic volume index is 37 ml/m2 (normal range 31+/-9).Right AtriumThe right atrium is moderately dilated.Aortic ValveThe aortic valve is trileaflet, opens widely and there is no significant aortic regurgitation.Mitral ValveThe mitral valve opens widely and there is mild 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.Severely reduced LV EF without evidence for delayed enhancement.2.Severe left atrial enlargement3.LV morphology has the appearance of LV non-compaction.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
