There is wall thickening of the left ventricle with disproportionately enlarged ventricular septum, most pronounced at the anteroseptal myocardium consistent with asymmetric hypertrophic cardiomyopathy. Maximum wall thickening is measured 42 mm at the mid anterior septum. Small left ventricular cavity size is demonstrated.
Systolic anterior motion of the anterior mitral leaflet resulting to left ventricular outflow tract obstruction is also demonstrated.
There is also wall thickening involving the apical wall of the right ventricle extending to the anterior wall of the right ventricular outflow tract with a maximum wall thickness measuring 11.4 mm.
The left atrium is top normal in size. There is a linear structure (membrane) traversing the left atrial cavity attached to the secundum interatrial septum and the junction of the left inferior pulmonary vein and apical side of the left atrial wall (best seen in the 4-chamber view). This membrane divides the left atrium into a proximal chamber, containing the pulmonary venous confluence, and a distal left atrium, which contains the left atrial appendage. The left atrial findings are consistent with cor triatriatum.
