29-year-old male with family and personal history of hypertrophic cardiomyopathy Left VentricleThe left ventricle is normal in size with normal systolic function. There is left ventricular hypertrophy, worse at the basal septum (16 mm). The overall LV ejection fraction is 65%, the LV end diastolic volume index is 111 ml/m2 (normal range: 74+/-15), the LVEDV is 222 ml (normal range 142+/-34), the LV end systolic volume index is 38 ml/m2 (normal range 25+/-9), the LVESV is 77 ml (normal range 47+/-19), the LV mass index is 91 g/m2 (normal range 85+/-15), and the LV mass is 182 g (normal range 164+/-36). There are no regional wall motion abnormalities present. There is no significant late gadolinium enhancement to suggest the presence of an underlying fibrosing, infiltrative, or inflammatory process. There is a left ventricular crypt or diverticulum noted in the basal inferior wall. The native myocardial T1 relaxation time is within normal limits.Left AtriumThe left atrium is normal in size. Right VentricleThe right ventricle is mildly dilated with normal systolic function. The overall RV ejection fraction is 56%, the RV end diastolic volume index is 125 ml/m2 (normal range 82+/-16), the RVEDV is 251 ml (normal range 142+/-31), the RV end systolic volume index is 55 ml/m2 (normal range 31+/-9), and the RVESV is 140 ml (normal range 54+/-17).Right AtriumThe right atrium is normal in size.Aortic ValveThe aortic valve opens widely and there is no significant aortic regurgitation. There is mild outflow obstruction in the LVOT related to SAM and septal hypertrophy. Mitral ValveThere is mild chordal and leaflet systolic anterior motion with mild mitral regurgitation. There is mild anterior leaflet bowing into the left atrium.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 mildly dilated (32 mm).Venous AnatomyThe SVC and IVC are normal in size and drain normally into the right atrium.PericardiumThere is a trivial pericardial effusion.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. Hypertrophic cardiomyopathy with maximum wall thickness of 16mm in the basal septum. No evidence of underlying myocardial fibrosis, inflammation, or infiltration.2. Normal left ventricular systolic function (LVEF 65%) with evidence of a left ventricular crypt or diverticulum involving the basal inferior wall. 3. Mild right ventricular dilation with normal systolic function (RVEF 56%). 4. Systolic anterior motion of the mitral leaflet with mild left ventricular outflow tract obstruction.5. Mild dilation of the main pulmonary artery. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
