Which dietary modification is recommended for Stage B2 MMVR?

• A. High protein diet
• B. Low potassium diet
• C. Mild sodium restriction diet
• D. High fat diet

Answer: (C)

Stage B2 MMVR represents structural heart disease without clinical heart failure yet, so the goal is to support the heart's function and prevent fluid buildup. A mild sodium restriction helps achieve this by limiting extracellular fluid volume and reducing the heart’s workload, which can slow progression toward congestive signs. It provides a practical, steady approach to volume management without risking energy or protein intake. The other options don’t address fluid balance in the same targeted way: high protein or high fat diets don’t specifically aid in managing the hemodynamics of mitral valve disease, and a low potassium diet could jeopardize cardiac electrical stability, especially if meds that affect potassium are used.
