USMLERx says that mitral stenosis leads to pedal edema. Why wouldn't it be pulmonary edema?

99% sure thats a typo. Pulm edema is more common. ALthough i guess you could get RHF if it was bad enough and that could eventually lead to pedal edema

I thought it might be a mistake, but wanted to double check.

Thanks!

Yeah. Pedal edema would be a late finding.

Mitral stenosis leads to a transvalvular gradient with increased left atrial pressure. This in turn can lead to pulmonary venous congestion and cardiogenic pulmonary edema. You can tell it's cardiogenic rather than noncardiogenic, because the LAP (or PCWP) is greater than 18mmHg. If it isn't fixed, the patient will end up with Group II pulmonary hypertension (pumonary venous hypertension) by the Evian Classification (Dana Point update). As mentioned above, if it progresses to RHF, there may be pedal edema. Can't imagine why else it would happen.
