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 ...
Pulmonary (or pulmonic [4]) regurgitation (or insufficiency, incompetence) is a condition in which the pulmonary valve is incompetent [5] and allows backflow from the pulmonary artery to the right ventricle of the heart during diastole. [6]
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]

This view is obtained in the same window as the parasternal long, but with the probe rotated 90°. In this view, the aortic valve is seen in cross-section with the right ventricular inflow & outflow tracts visible with the tricuspid valve as well. Pulmonary valve is not visible in this view. Both the right and left atria are visible.
In The Framingham Heart Study, presence of tricuspid regurgitation of mild severity or greater, was present in about 14.8% of men and 18.4% of women. [20] Mild tricuspid regurgitation tends to be common and, in the presence of a structurally normal tricuspid valve apparatus, can be considered a normal variant. [21]
However, slight rotation and insertion may be needed to better visualize the right heart and tricuspid valve. At 45°, the short-axis view of the aortic valve can be obtained. At this angle, a short-axis view of the right ventricle can be seen to visualize the right atrium, tricuspid valve, right ventricle, and pulmonary valve in a single view.
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]
