Which of the following are not generally associated with mitral stenosis without regurgitation?

A. Pulmonary hypertension.

B. Pulmonary edema. 

D. An opening snap after the second heart sound.

DISCUSSION: Pure mitral stenosis without regurgitation may be associated with pulmonary hypertension, pulmonary edema, and an opening snap after the second heart sound. Left ventricular dilatation would be rare in pure mitral stenosis and generally occurs with volume or pressure overload of the left ventricle, as with mitral regurgitation.
