Overview
Tricuspid atresia is a form of congenital heart disease whereby the following defects are seen: complete absence of the tricuspid valve, absence of right atrioventricular connection, hypoplastic or an absence of the right ventricle. For survival of the infant a right-to-left atrial shunt is necessary. Repair of this lesion occurs in the first week of life and involves surgical palliation usually in three stages.
Pathophysiology
In tricuspid atresia, there is no continuity between the right atrium and right ventricle. Blood from superior vena cava and inferior vena cava is forced across intra atrial connection into the left heart. As a consequence, oxygen saturation in the left atrial blood is diminished.
Causes
Like many other congenital heart diseases the causes of tricuspid atresia are not known.
Epidemiology and Demographics
Tricuspid atresia is an uncommon form of congenital heart disease that affects about 5 in every 100,000 live births. Twenty percent of patients with this condition will also have have other heart problems.
Risk Factors
As with all congenital heart diseases, families with a history of tricuspid atresia run a higher risk of passing it onto their children. Other potential factors include access to prenatal care and the mother's behavior during pregnancy (i.e. alcohol consumption, illicit drug use, etc).
Diagnosis
CT
Computed tomography can be helpful as a diagnostic tool in conditions where the echocardiographic findings are inconclusive.
MRI
Magnetic resonance imaging can be helpful as a diagnostic tool in conditions where the echocardiographic findings are inconclusive.
Echocardiography
2D-Echocardiography along with doppler ultrasonography helps in diagnosing tricuspid atresia. The anatomy, type of defects, associated defects, type of flow and resistance can be determined by this.
Treatment
Primary Prevention
There is no known way to prevent tricuspid atresia.
