Mitral regurgitation or tricuspid regurgitation is the medical term meaning backflow of blood through the mitral or tricuspid valves, respectively.
congenital tricuspid valve deformity leading to pathologic regurgitation
Most of the time its caused because of retrograde pulmonary hypertension, so if whatever is causing it is dealt with, the tricuspid regurgitation should stop, since its a functional response and not necessarily pathological. On the other hand, if it was caused by direct damage to the tricuspid valve, then it can't be repaired and has to be replaced with a prosthesis
It closes, preventing regurgitation of blood back into the right atrium.
Mitral valve insufficiency is a term used when the valve between the upper left chamber of the heart (atrium) and the lower left chamber (ventricle) does not close well enough to prevent back flow of blood when the ventricle contracts.

The closest I found was regurgitate which is to throw or be thrown back or out;vomit is regurgitation
The right ventricle of the heart typically contains three papillary muscles: anterior, posterior, and septal. These muscles attach to the tricuspid valve leaflets via chordae tendineae to help prevent valve regurgitation.
Tricuspids is the plural of tricuspid
If the tendinous cord, also known as the chordae tendineae, is not present and the right ventricle contracts, the blood would flow backwards into the right atrium instead of being pumped out into the pulmonary artery. This condition is known as tricuspid regurgitation or tricuspid insufficiency.

Depending on what you mean by "trace", the answer could be yes or no.
