MRI CARD WWO CNTRST, VIABLTY/SCAR IMAG.MORPH/FUNCT,W/FLOW/VELOCITY MEASURE, 8/30/2016 9:15 AM Left VentricleThe left ventricle is normal in size with normal systolic function. There is severe concentric left ventricular hypertrophy. The IVSd and PWd range between 16-19mm with the apical posterior wall being most hypertrophied. The overall LV ejection fraction is 61%. The LVEDV is 257 ml (normal range 142+/-34), the LV end diastolic volume index is 107 ml/m2 (normal range: 74+/-15), the LVESV is 100 ml (normal range 47+/-19) and the LV end systolic volume index is 42 ml/m2 (normal range 25+/-9). The LV mass is 335 g (normal range 164+/-36) and the LV mass index is 139 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 replacement fibrosing, infiltrative, or inflammatory process.The native T1 myocardial relaxation time is normal (1050 ms) in the septum; however, the inferolateral wall has mildly increased native T1 myocardial relaxation time (T1=1134ms). Elevations in native myocardial T1 relaxation time suggests the presence of underlying interstitial fibrosis. There is no myocardial iron overload. There is no LV thrombus. Left AtriumThe left atrium is mildly dilated. Right VentricleThe right ventricle is normal in size with normal systolic function. The overall RV ejection fraction is 53%. The RVEDV is 259 ml (normal range 142+/-31), RV end diastolic volume index is 108 ml/m2 (normal range 82+/-16), the RVESV is 122 ml (normal range 54+/-17), and the RV end systolic volume index is 51 ml/m2 (normal range 31+/-9).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 mild mitral regurgitation. No evidence of systolic anterior motion of the mitral leaflets or dynamic LVOT obstruction. Pulmonic ValveThe pulmonic valve opens widely. There is no significant pulmonic regurgitation.Tricuspid ValveThe tricuspid valve opens widely. There is mild tricuspid regurgitation.AortaThere is a left sided aortic arch with a normal brachiocephalic branching pattern. The aortic root is normal in size. No evidence of thoracic coarctation, aneurysm, or dissection. 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.Severe concentric left ventricular hypertrophy (16-19mm wall thickness) with normal systolic function without evidence of underlying myocardial replacement fibrosis, inflammation, or infiltration. There is, however, a mild increase in native myocardial T1 relaxation time along the inferolateral wall which may suggest presence of interstitial fibrosis. 2.No signs of infiltrative disease such as amyloid, iron overload, or Fabry's. 3.Normal-sized right ventricle with normal systolic function.4.Mild left atrial dilation. 5.Normal origin of the coronary arteries. 6.No evidence of aortic coarctation, dissection, or aneurysm. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
