Tricuspid regurgitation (TR), also called tricuspid insufficiency, is a type of valvular heart disease in which the tricuspid valve of the heart, located between the right atrium and right ventricle, does not close completely when the right ventricle contracts .
Since the main causes of right ventricular hypertrophy is tricuspid regurgitation or pulmonary hypertension (discussed above), management involves treatment of these conditions. [3] Tricuspid regurgitation is typically treated conservatively by aiming to treat the underlying cause and following up the patient regularly. [ 12 ]
In The Framingham Heart Study presence of any severity of tricuspid regurgitation, ranging from trace to above moderate was in 82% of men and in 85.7% of women. [2] Mild tricuspid regurgitation tend to be common and benign and in structurally normal tricuspid valve apparatus can be considered a normal variant. [1]
The tricuspid valve, or right atrioventricular valve, is on the right dorsal side of the mammalian heart, at the superior portion of the right ventricle.The function of the valve is to allow blood to flow from the right atrium to the right ventricle during diastole, and to close to prevent backflow (regurgitation) from the right ventricle into the right atrium during right ventricular ...
In this view, the mitral valve, tricuspid valve, and all four chambers are visible. This view shows the right ventricle from base to apex and is a useful view to estimate RV systolic function. TAPSE (= tricuspid annular plane systolic excursion) is also measured in this view with M-mode through the lateral tricuspid annulus. Structures:
Lancisi's sign is a clinical sign in which a large venous wave, or Giant V wave, is visible in the jugular vein in patients with tricuspid regurgitation. It is caused by blood flowing backwards into the jugular vein through the incompetent tricuspid valve during ventricular systole. [1] The sign is named after Giovanni Maria Lancisi. [2]
Tricuspid regurgitation Carvallo's sign is a clinical sign found in patients with tricuspid regurgitation . The pansystolic murmur found in this condition becomes louder during inspiration ; this sign enables it to be distinguished from mitral regurgitation .
Tricuspid regurgitation is usually secondary to right ventricular dilation [16] which may be due to left ventricular failure (the most common cause), right ventricular infarction, inferior myocardial infarction, [16] or cor pulmonale [16] Other causes of tricuspid regurgitation include carcinoid syndrome and myxomatous degeneration.
