Which condition is NOT a cause of right-sided heart failure?

Mitral stenosis is primarily associated with left-sided heart failure rather than right-sided heart failure. This condition involves the narrowing of the mitral valve, which impedes blood flow from the left atrium to the left ventricle. As a result, increased pressure in the left atrium can lead to pulmonary congestion and left-sided heart failure. While it may indirectly contribute to right-sided heart issues over time due to biventricular failure, it is not a direct cause of right-sided heart failure.

In contrast, tricuspid valve disease and pulmonary hypertension are directly linked to right-sided heart failure. Tricuspid valve disease affects the right side of the heart, impeding blood flow to the lungs and leading to increased pressure in the right atrium. Pulmonary hypertension poses increased resistance against the right ventricle, making it work harder, which can ultimately lead to right-sided heart failure. Congestive hepatosplenomegaly can also occur as a consequence of right-sided heart failure, reflecting the effects of systemic venous congestion, but it does not cause it.
