Left Ventricular Dilatation
Left Ventricular Dilatation

View is of left ventricular outflow tract showing aortic valve. Note posterior papillary muscle arising from posterior wall of left ventricle (1 arrow), and anterior papillary muscle arising from anterolateral wall (2 arrows).
The rest of the left ventricular wall is a dilated interventricular septum (
), which shows a flattening of the trabeculae carnae, characteristic of dilatation.
