Stenotic Atrioventricular Valve Disease Tricuspid Stenosis (TS)
Can be similar to the symptoms of MS…please refer back to the clinical presentation for MS.
Note: TS and MS can be coexisting due to rheumatic heart disease.
auscultation: similar to MS…hear an “opening snap” (OS) after S2; OS followed by low-frequency decrescendo diastolic murmur – the murmur of TS is heard closer to the sternum and intensifies on inspiration due to increased right heart blood flow (more volume over stenosis = louder murmur)
jugular venous pulse: neck waves are distended with a large “a” wave due to RA contraction against the stenotic tricuspid valve orifice
patients may develop abdominal distention and hepatomegaly due to passive venous congestion
Typical path features of rheumatic TS come from acute and recurrent inflammation – like with MS, get fibrous thickening, calcification of valve leaflets, fusion of valve commissures, and thickening and shortening of the chordae tendineae.
TS is rare and usually a consequence of rheumatic heart disease.
oSurgical therapy usually required – either valvuloplasty or valve replacement.
