Answer

Mitral stenosis

In severe mitral stenosis, LAP, and thus PAWP, is elevated. Pulmonary hypertension also develops as the severity of the valve lesion progresses. This leads to increase in RV systolic pressure and in the RA A wave. RV diastolic pressure may increase if RV failure or important tricuspid regurgitation develops. Atrial fibrillation is a common complication in mitral stenosis and results in loss of A waves in both the RA and PCWP pressure tracings.
