Most common etiology is a late complication of acute rheumatic fever.
Rarely occurs in the absence of associated rheumatic mitral and/or aortic disease.
Dyspnea is a common finding and usually relates to concomitant mitral valve stenosis.
Prominent a-waves in the jugular venous wave form are a hallmark of tricuspid stenosis in patients who are in sinus rhythm.
Transthoracic echocardiogram with Doppler flow is accurate for diagnosis.
Most effective therapy is valve replacement.
