Tricuspid valve stenosis is a narrowing of the orifice of the tricuspid valve of the heart. This causes increased resistance to blood flow through the valve. It is almost always caused by rheumatic fever and is generally accompanied by mitral stenosis. Rare other causes include carcinoid syndrome, endocarditis, endomyocardial fibrosis, lupus erythematosus, right atrial myxoma and congenital tricuspid atresia.
[edit] Diagnosis
A murmur can be heard during auscultation caused 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). Using echocardiography the stenotic valve can be visualized and the severity can be measured.
