Which sided heart failure would you find peripheral dependent edema?

• A. Left Sided Heart Failure
• B. Biventricular Failure
• C. Right Sided Heart Failure
• D. Pulmonary Hypertension

Answer: (C)

Peripheral dependent edema happens when blood backs up in the systemic veins, raising venous pressure in tissues like the legs. This is a hallmark of the right side of the heart failing to move blood forward into the lungs. When the right ventricle can’t pump effectively, fluid leaks out of capillaries into interstitial spaces, and gravity makes swelling appear most in dependent areas such as the ankles and feet (and sacral area if someone is immobile). In contrast, left-sided heart failure pushes fluid backward into the lungs, causing pulmonary edema and breathing difficulties, not the peripheral leg swelling described here. Pulmonary hypertension increases the right heart’s workload but isn’t by itself the cause of peripheral edema. While involvement of both sides can occur (biventricular failure), the clear association with systemic venous congestion and leg edema points to right-sided failure.
