Right-Sided Heart Failure

Right-sided heart failure occurs when the right side of the heart is unable to pump enough blood to the lungs. This often happens as a result of left-sided heart failure, which causes increased fluid pressure in the lungs and damages the right side of the heart. As a result, blood can back up in the veins, leading to fluid accumulation in organs and tissues throughout the body, causing swelling in the legs, ankles, abdomen, and other areas.
