Moderate to severe MS leads to which of the following?

Explanation:
Moderate to severe mitral stenosis creates a bottleneck for blood flow from the left atrium to the left ventricle, raising left atrial pressure. That pressure backs up into the pulmonary veins and capillaries, which over time elevates pressures in the pulmonary circulation, leading to pulmonary hypertension. Pulmonary edema can occur in the setting of very high left atrial pressure, but the characteristic consequence of significant MS is increased pulmonary pressures. Systemic hypertension and aortic stenosis are not direct results of mitral stenosis.
