44 year old woman with NICM, referred for evaluation of underlying scar. Left VentricleThe left ventricle is severely dilated with severely reduced systolic function. The overall LV ejection fraction is 6%, the LV end diastolic volume index is 130 ml/m2 (normal range: 65+/-11), the LVEDV is 328 ml (normal range 109+/-23), the LV end systolic volume index is 123 ml/m2 (normal range 18+/-5), the LVESV is 309 ml (normal range 31+/-10). LV dysfunction is global with regional variation. The delayed enhancement images are non-diagnostic, thus determination of late gadolinium enhancement is not possible on this study. Morphology of the left ventricle myocardium is sugegstive of LV non-compaction. There is an extensive LV thrombus present in the apex as, but also extending up the walls of the LV to the mid LV cavity.Left AtriumThe left atrium is mildly dilated. Right VentricleThe right ventricle is normal in size with severely reduced systolic function. The overall RV ejection fraction is 10%, the RV end diastolic volume index is 87 ml/m2 (normal range 69+/-14), the RVEDV is 219 ml (normal range 110+/-24), the RV end systolic volume index is 79 ml/m2 (normal range 22+/-8), and the RVESV is 197 ml (normal range 35+/-13). Right AtriumThe right atrium is mild-moderately dilated. Aortic ValveThe aortic valve 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 is not well visualized.Tricuspid ValveThe tricuspid valve opens widely. There is mild tricuspid regurgitation.AortaThe aortic root is not well visualized.Pulmonary VeinsAll four pulmonary veins drain normally into the left atrium.Pulmonary ArteryThe main pulmonary artery is not well visualizedVenous AnatomyThe SVC and IVC drain normally into the right atrium. PericardiumThere is no obvious pericardial disease.Extracardiac FindingsLeft chest ICD present. 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. The left ventricle is severely dilated with severely reduced systolic function. The overall LV ejection fraction is 6%. LV dysfunction is global with regional variation. 2. The right ventricle is normal in size with severely reduced systolic function. The overall RV ejection fraction is 10%. 3. There is an extensive LV thrombus present in the apex as, but also extending up the walls of the LV to the mid LV cavity.4. Morphology of the left ventricle myocardium is suggestive of LV non-compaction. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
