There is a problem when the valve that controls what blood is good and what blood is used, no longer is strong enough to control this flow. Heart valves get damaged or simply wear out. I think you are asking what causes blood to flow in the wrong direction. My guess is that it would be a faulty heart valve.
Right side heart failure is a condition when the right side of the heart can no longer pump blood efficiently. Itâs also known as congestive heart failure because as the right side of the heart loses it strength, blood can back up or become congested. Arrhythmogenic right ventricular dysplasia is a rare genetic defect where the right ventricleâs muscle is replaced with fat and scar tissue.
