As blood regurgitates into the left ventricle between each systole, volume overload ensues and the ventricular wall hypertrophies in an attempt to maintain cardiac output and blood pressure. The massive ventricle can lead to a heart weighing over 1000 grams (the weight of a normal heart is about 350 grams), referred to as cor bovinum (Latin for cow's heart).
As blood flows back into the left ventricle between each heartbeat, it causes an accumulation of volume and the ventricular wall thickens in a bid to maintain cardiac output and pressure. This can result in a heart that is excessively enlarged, weighing over 1000 grams, referred to as cor bovinum.
