Tricuspid regurgitation is a disorder in which the heart's tricuspid valve does not close properly, causing blood to flow backward (leak) into the right upper heart chamber (atrium) when the right lower heart chamber (ventricle) contracts.
Alternative NamesTricuspid insufficiency
Causes, incidence, and risk factorsThe tricuspid valve separates the right lower heart chamber (the right ventricle) from the right upper heart chamber (right atrium).
The most common cause of tricuspid regurgitation is swelling of the right ventricle. Such swelling may be a complication of any disorder that causes failure of the right ventricle.
Tricuspid regurgitation may also be caused by or made worse by valve disease on the left side of the heart such as mitral regugitation and mitral stenosis.
Other diseases can directly affect the tricuspid valve. The most common of these is rheumatic fever, which is a complication of untreated strep throat infections.
Tricuspid regurgitation may be found in those with a type of congenital Heart disease called Ebstein's anomaly.
Other infrequent causes of tricuspid regurgitation include:
Another important risk factor for tricuspid regurgitation is use of the diet medications called "Fen-Phen" (phentermine and fenfluramine) or dexfenfluramine.
SymptomsTricuspid regurgitation may not cause any symptoms if the patient does not have pulmonary hypertension. If pulmonary hypertension and moderate to severe tricuspid regurgitation exist together, the following symptoms may result:
The health care provider may detect abnormalities when when gently pressing with the hand (palpating) on your chest. The doctor may also feel a pulse over your liver. The physical exam may reveal liver and spleen swelling.
Listening to the heart with a stethoscope shows a murmur or abnormal sounds.There may be signs of fluid collection in the abdomen.
An ECG or echocardiogram may show swelling of the right side of the heart. Doppler echocardiography or right-sided cardiac catheterization are used to measure blood pressures inside the heart and lungs.
TreatmentTreatment may not be needed if there are few or no symptoms. Hospitalization may be required for diagnosis and treatment of severe symptoms.
Swelling may be managed by medications (diuretics) that help remove fluids from the body.
Underlying disorders should be identified and treated. Some people may be able to have surgery to repair or replace the tricuspid valve. When surgical treatment is done it is usually done as part of another procedure, most commonly mitral valve repair for mitral regurgitation.
Expectations (prognosis)Treatment of any underlying conditions, especially high blood pressure in the lungs and swelling of the right lower heart chamber, may correct the disorder. Surgical valve repair or replacement usually provides a cure. However, persons with severe tricuspid regurgitation that cannot be corrected may have a poor prognosis.
ComplicationsCall your health care provider if symptoms of tricuspid regurgitation are present.
PreventionPrompt treatment of disorders that can cause valve disease reduces your risk of tricuspid regurgitation. Treat strep infections promptly to prevent rheumatic fever.
Any invasive procedure, including dental work and cleaning, can introduce bacteria into your bloodstream. The bacteria can infect a damaged mitral valve, causing endocarditis. Always tell your health care provider and dentist if you have a history of heart valve disease or congenital heart disease before treatment. Taking antibiotics before dental or other invasive procedures may decrease your risk of endocarditis.

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
What you should do is search it on google b! :) xx
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 tricuspid valve is one of the four main heart valves, located between the right atrium and right ventricle. It consists of three leaflets that open and close to regulate blood flow, preventing backflow into the atrium during ventricular contraction. The valve plays a crucial role in maintaining efficient circulation by ensuring that deoxygenated blood moves from the right atrium into the right ventricle, where it is then pumped to the lungs for oxygenation. Dysfunction of the tricuspid valve can lead to conditions such as tricuspid regurgitation or stenosis.
In tricuspid regurgitation, the pansystolic murmur can increase during inspiration due to the increase in venous return to the right side of the heart. During inspiration, intrathoracic pressure decreases, allowing more blood to flow into the right atrium. This increased volume enhances the regurgitant flow across the incompetent tricuspid valve, thus amplifying the murmur. Additionally, the increased right ventricular filling can lead to a more pronounced murmur during this phase of the respiratory cycle.
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
The blood would go back up into the right atrium instead of preceding to the pulmonary arteries because the tendinous cords cause the tricuspid valve to open and close based on which state of the cardiac cycle the heart is in.
The Tricuspid valve is in the heart, not the feet
