Tricuspid valve stenosis is a
valvular heart diseasewhich results in the narrowing of the orifice of the tricuspid valveof the heart. This causes increased resistance to blood flow through the valve. It is almost always caused by rheumatic feverand is generally accompanied by mitral stenosis. Rare other causes include carcinoid syndrome, endocarditis, endomyocardial fibrosis, lupus erythematosus, right atrial myxomaand congenital tricuspid atresia.
diastolicmurmur can be heard during auscultationcaused by the blood flow through the stenotic valve. It is best heard over the left sternal border with rumbling character and tricuspid opening snap with wide splitting S1. May increase in intensity with inspiration ( Carvallo's sign). The diagnosis and the severity can be assessed by echocardiography.
The treatment is usually by surgery (tricuspid
valve replacement) or percutaneous balloon valvuloplasty. The resultant tricuspid regurgitation from percutaneous treatment is better tolerated than insufficiency occurring during mitral valvuloplasty
