According to the material, right-sided heart failure will eventually turn into left-sided heart failure.

• A. False
• B. Not sure
• C. True
• D. It depends

Answer: (C)

The idea here is about how the two ventricles influence each other in heart failure. When the right ventricle starts to fail, it often dilates and pressures rise in the right heart. This can push the septum toward the left ventricle, limiting how much the left ventricle can fill. With less filling, the left ventricle pumps less blood, so left-sided signs and symptoms of failure can emerge. Over time, the problem on the right can therefore progress to involve the left side, leading to a pattern of biventricular heart failure. In practice, this interdependence means a right-sided failure isn’t always isolated; many patients develop left-sided involvement as the disease evolves.
