2025年1月21日 · Tricuspid atresia is a heart problem present at birth, known as a congenital heart defect. The valve isn't formed between the two right heart chambers. Instead, a solid sheet of tissue blocks the blood flow between the right heart chambers. The condition limits blood flow through the heart.

2022年6月28日 · Tricuspid atresia, a condition you’re born with, is a heart problem in which your tricuspid valve doesn’t exist. Without this valve, blood can’t flow normally from your upper to lower chambers on the right side of your heart.

Tricuspid atresia is a single-ventricle defect, because the heart has only one functioning ventricle (the left ventricle). Tricuspid atresia symptoms in children include: Tricuspid atresia may be diagnosed before birth, with a special kind of ultrasound called a fetal echocardiogram.

2024年1月26日 · Tricuspid atresia is a congenital heart defect that results in cyanosis due to the absence of communication between the right atrium and ventricle caused by the complete agenesis of the tricuspid valve.

2024年10月21日 · Tricuspid atresia (pronounced try-CUSP-id uh-TREE-zhuh) is a congenital heart defect. Congenital means present at birth. It occurs when the tricuspid valve in the heart does not form at all. Surgical repairs for tricuspid atresia aren't a cure.

Tricuspid atresia is a form of congenital heart disease whereby there is a complete absence of the tricuspid valve. [2] . Therefore, there is an absence of right atrioventricular connection. [2] . This leads to a hypoplastic (undersized) or absent right ventricle.

Tricuspid atresia (TA) occurs when the tricuspid valve does not develop correctly. This prevents blood flow from the right atrium to the right ventricle. TA may be identified during a prenatal ultrasound or shortly after birth when the baby has symptoms like turning blue (cyanotic).

Tricuspid atresia is a serious congenital (present at birth) heart defect caused by the absence of a crucial heart valve. While the fetus’s heart is being formed, the tricuspid valve does not develop; instead, a solid ridge of tissue appears where this valve should be.

A rare congenital heart malformation characterized by absence of the tricuspid valuvar annulus (absent right atrioventricular connection/junction) or an imperforate tricuspid valve leading to severe hypoplasia of right ventricle (functionally univentricular heart).

In tricuspid atresia, the tricuspid valve — which is normally located between the right atrium and the right ventricle — is missing, as is the right ventricle. While very serious, tricuspid atresia is treatable surgically, and surgical advances have greatly improved outcomes.
