why does too much blood pump on right side of heart

[allmanrebel]

my step-daughter is 33 she lives in ga. she was born with arthogryposis. shes had a normal life.but ,a few months ago she was put on oxygen.she went to the hospital last week saying she had some difficulty breathing. now, i heard the right side of her heart is pumping too much blood. one side of her heart is bigger than the other. what does this

For a perspective, when the left ventricle is not pumping efficienctly (meaning the heart is pumping significallty less blood into circulation than it receives from the right side of the heart).  The blood backs up causing an increase in heart size in an attempt to compensate. That is the usual cardiovascular issue.

The breathing issue may be due to the blood backing up into the chest causing fluids to leak into the lungs.  This will effect breathing and sometimes a dry cough...worst case scenario. Would need more information usually from an echocardiogram that includes chamber size. left ventricle ejection fraction (percent of blood pumped with each heartbeat), and structure abnormality, etc.

Hope this helps, and if you have any further questions or comments, you are welcome to respond.  Take care, and thanks for sharing.
