It would help if you could give a little more context. I presume we are referring to the function of the ventricle rather than any anatomical anomalies, however I shall wait for confirmation from our esteemed colleagues! :o)

Constrictive pericarditis results in a variety of echocardiographic abnormalities including pericardial thickening; biatrial enlargement with good left ventricular function; a diastolic septal bounce; and a dilated inferior vena cava without significant respiratory variation.
