18 year-old male with symptomatic NSVT. MRI to rule look for structural abnormality Left VentricleThe left ventricle is moderately dilated LV with mildly reduced systolic function . The overall LV ejection fraction is 50%, the LV end diastolic volume index is 136 ml/m2 (normal range: 74+/-15), the LVEDV is 293 ml (normal range 142+/-34), the LV end systolic volume index is 68 ml/m2 (normal range 25+/-9), the LVESV is 147 ml (normal range 47+/-19), the LV mass index is 62 g/m2 (normal range 85+/-15), and the LV mass is 133 g (normal range 164+/-36). There is global kLV hypokinesis. There is no late gadolinium enhancement to suggest the presence of an underlying fibrosing, infiltrative, or inflammatory process.Left AtriumThe left atrium is normal in size. Right VentricleThe right ventricle is normal in size and systolic function. The overall RV ejection fraction is 54%, the RV end diastolic volume index is 119 ml/m2 (normal range 82+/-16), the RVEDV is 257 ml (normal range 142+/-31), the RV end systolic volume index is 55 ml/m2 (normal range 31+/-9), and the RVESV is 119 ml (normal range 54+/-17). There is no evidence RV akinesia or dyskinesia.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 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. The origins of the right and left coronaries are normal. 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 are normal in size and 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. The left ventricle is moderately dilated LV with mildly reduced systolic function . The overall LV ejection fraction is 50%2. The right ventricle is normal in size and systolic function. The overall RV ejection fraction is 54%. The indexed RVEDV is >110 mL/m2 however there is no evidence of RV akinesia or dyskinesia and therefore the patient does not meet major or minor criteria for ARVC.3. Normal origin of right and left coronaries.
