In this four chamber view, what strikes our attention as we observe this heart contracting? First, certainly, there's a bit of poor contractility of the left ventricle. Although, perhaps even more important and more striking than that is the overall size of the left ventricle. It appears to be balloon-shaped with poor contraction, and overall, it takes up a fair amount of the viewing screen as compared to the rather small and relatively well-contracting right ventricle.
This view, overall, although be it a four chamber, should probably be more correctly called a five chamber, since the aortic valve comes in and out of view as the heart contracts. Hearts become this shape based on volume overload, not necessarily pressure overload, and it would appear that likely this is the case. Perhaps there's a fair amount of aortic regurgitation such that the overall heart dilates to accommodate the extra load of volume that the left heart receives.
