Tricuspid atresia

Common Name(s)

Tricuspid atresia

Tricuspid atresia is a heart defect that is present at birth. The tricuspid valve is one of four heart valves which ensure that blood flows in the correct direction at the correct time. The tricuspid valve connects the right upper chamber (atrium) to the right lower chamber (ventricle) of the heart. Individuals with tricuspid atresia have solid tissue where the valve should be, which prevents blood from passing through. This leads to an absent or undersized right ventricle. Blood can no longer flow from the right ventricle into the lungs to be oxygenated. Instead, blood flows through holes in the heart walls that should normally close after birth. This abnormal movement of blood is less effective than normal movement of blood through the heart, and babies who are born with this defect require surgery.

Symptoms of tricuspid atresia include tiring easily, blue-tinted skin (cyanosis), shortness of breath, and poor growth. These symptoms are usually visible shortly after birth. Additional symptoms include swelling of the legs, arms, feet, or abdomen. A doctor may notice a swishing sound when listening to the heart (murmur) or a rapid heartbeat. Individuals who have Down syndrome are at an increased risk of having tricuspid atresia. The risk of tricuspid atresia also increases if the mother is infected with rubella, drinks alcohol, or has uncontrolled diabetes during pregnancy.

A diagnosis of tricuspid atresia can be made prior to birth with an ultrasound. Once the baby is born, an echocardiogram is usually performed to confirm the diagnosis. Treatment will usually involve at least one surgery to ensure that the heart is able to pump adequate amounts of oxygenated blood to the body. Continued follow-up and medications are also important to prevent any complications. Talk to your child’s doctor about the most current treatment options. Support groups are also available for more information.

Successful staged Fontan completion for a tricuspid atresia patient with left ventricular non-compaction.
 

Author(s): Masatoshi Shimada, Takahiko Sakamoto, Kentaro Umezu, Yorikazu Harada

Journal: Interact Cardiovasc Thorac Surg. 2016 Mar;22(3):387-9.

 

We report a case of Fontan completion for a tricuspid atresia (TA) patient with left ventricular non-compaction (LVNC). The patient was diagnosed with TA (Ia) with LVNC by fetal echocardiography. Because the unfavourable prognosis of LVNC was anticipated, Imidapril as well as Carvedilol ...

Prenatal tricuspid valve size as a predictor of postnatal outcome in patients with severe pulmonary stenosis or pulmonary atresia with intact ventricular septum.
 

Author(s): Alexander Lowenthal, Breniel Lemley, Alaina K Kipps, Michael M Brook, Anita J Moon-Grady

Journal: Fetal. Diagn. Ther.. 2014 ;35(2):101-7.

 

Tricuspid valve (TV) size at birth correlates with intervention strategy in patients with severe pulmonary stenosis (SPS) or pulmonary atresia/intact ventricular septum (PA/IVS). Prenatal features that might predict postnatal TV size have not been well studied. We hypothesized that ...
