18 year old female with syncope and possible right ventricular dilation referred to evaluate for ARVD and other causes of syncope. Left VentricleThe left ventricle is severely dilated with normal systolic function. The overall LV ejection fraction is 60%, the LV end diastolic volume index is 136 ml/m2 (normal range: 65+/-11), the LVEDV is 219 ml (normal range 109+/-23), the LV end systolic volume index is 55 ml/m2 (normal range 18+/-5), the LVESV is 88 ml (normal range 31+/-10), the LV mass index is 72 g/m2 (normal range 67+/-11), and the LV mass is 117 g (normal range 114+/-24). 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.Left AtriumThe left atrium is normal in volume.Right VentricleThe right ventricle is severely dilated with normal systolic function. The overall RV ejection fraction is 54%, the RV end diastolic volume index is 136 ml/m2 (normal range 69+/-14), the RVEDV is 220 ml (normal range 110+/-24), the RV end systolic volume index is 62 ml/m2 (normal range 22+/-8), and the RVESV is 100 ml (normal range 35+/-13). Right AtriumThe right atrium is normal in volume. 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. Normal origin of the coronary arteries.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 FindingsEvidence of spine surgery noted. 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. Severe LV dilation with normal systolic function (LVEF 60%) without evidence of underlying myocardial fibrosis, inflammation, or infiltration.2. Severe RV dilation with normal systolic function (RVEF 54%) without evidence of focal aneurysm or wall motion abnormality. No cardiac MRI evidence of ARVD.3. Normal biatrial volume.4. Normal coronary artery origins. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
