Answer :
Severe peripheral edema in a person with right-sided heart failure is likely caused by increased hydrostatic pressure, which leads to fluid leakage into tissues.
The most likely cause of severe peripheral edema in a person with right-sided heart failure is increased hydrostatic pressure within peripheral capillaries. In right-sided heart failure, the right ventricle cannot effectively pump blood to the lungs, leading to a back up of blood in the systemic circulation. This backlog increases venous pressure, which in turn raises capillary hydrostatic pressure and causes fluid to leak into the interstitial space, causing edema.
