Tricuspid regurgitation is a condition divided into four stages based on several factors. Treatment for the condition varies based on the stage and symptoms and may include watchful waiting or, in some cases, surgery.
Tricuspid regurgitation is a type of heart disease that occurs when the tricuspid valve doesn’t close properly. It can cause a backward flow of blood from a section of the heart called the right ventricle to the right atrium.
- valve anatomy
- severity of valve dysfunction
In this article, we examine the stages of tricuspid regurgitation and how treatment varies by stage.
Where is the tricuspid valve?
- Tricuspid leaflets: three flaps of tissue that make up the valve
- Papillary muscles: muscles that contract to close the valve
- Chordae: small, stringy structures that allow the papillary muscles to pull the valve shut
- Annulus: the structure that forms the attachment for the three leaflets
Doctors may be able to notice a
As many as
The ACC and AHA guidelines characterize progressive tricuspid regurgitation (stage B) as a regurgitant volume, or volume of blood flowing backward, of less than
With stage B, the annulus may be enlarged, and there might be mild or moderate tethering of the leaflets. Tethering means the leaflets are pulled out of their typical location by the stringy chordae.
People with stage B tricuspid regurgitation
At this stage, people don’t experience symptoms.
People with stage D tricuspid regurgitation have severe annular enlargement and leaflet tethering. They right ventricle and atrium are also enlarged.
People can experience symptoms of right-sided heart failure.
Transthoracic echocardiography is the
Here’s a look at how treatment for tricuspid regurgitation varies by stage.
Stage A tricuspid regurgitation typically doesn’t require treatment.
- enlargement of the annulus greater than 4 centimeters
- prior symptoms of right-sided heart failure
Stages C and D
People with stage C and D, a more severe form of the disease. may benefit from
According to the guidelines, surgery can help reduce symptoms in people with stage D and symptoms of right-sided heart failure.
A doctor may consider surgery for people with stage C disease and progressive right ventricle enlargement.
People with heart valve disease that develops slowly over the years often don’t have symptoms. If heart valve disease develops quickly, symptoms
Seek medical attention if you develop symptoms of heart valve disease. If you have previously received a tricuspid dysfunction diagnosis, it’s important to go to all your scheduled follow-ups.
Here are some frequently asked questions people have about tricuspid regurgitation.
Does tricuspid valve regurgitation always progress?
Mild tricuspid valve regurgitation often doesn’t progress to a more advanced stage.
In a 2023 study, researchers found that 19% of 1,843 people with at least moderate tricuspid regurgitation experienced progression at a median follow-up of 2.3 years. The progression rates at 1, 2, and 3 years were 4.9%, 10.1%, and 24.8%, respectively.
Should I worry about mild tricuspid regurgitation?
Mild tricuspid regurgitation is very common in the general population and usually doesn’t cause any issues or affect life expectancy.
What is the prognosis for tricuspid regurgitation?
People with mild tricuspid regurgitation often never develop issues.
Severe forms of tricuspid regurgitation may have a
What is life expectancy with tricuspid regurgitation?
Tricuspid regurgitation is a condition characterized by the backflow of blood through the tricuspid valve. It can range from mild to severe.
The ACC and AHA’s most recent guidelines divide tricuspid regurgitation into stages A–D. While people with mild disease often don’t develop any issues, people with a severe form of the disease often need surgery.
