==Overview==
==[[Tricuspid atresia pathophysiology|Pathophysiology]]==
'''Tricuspid atresia''' is a form of [[congenital heart disease]] whereby there is a complete absence of the [[tricuspid valve]]. Therefore, there is an absence of right atrioventricular connection. This leads to a [[hypoplastic]] or an absence of the [[right ventricle]].


==Pathophysiology==
==Diagnosis==
This defect occurs during prenatal development.  Because of the lack of an A-V connection, an [[atrial septal defect]] (ASD) ''must'' be present to maintain blood flow. Also, since there is a lack of a right ventricle there ''must'' be a way to pump blood into the [[pulmonary arteries]], and this is accomplished by a [[ventricular septal defect]] (VSD).
[[Tricuspid atresia history and symptoms|History and symptoms]]
 
Blood is mixed in the [[left atrium]]. Because the only way the pulmonary circulation receives blood is through the VSD, a [[patent ductus arteriosus]] is usually also formed to increase pulmonary flow.
 
==Clinical manifestations==
* progressive [[cyanosis]]
* [[Poor feeding]]
* [[Tachypnea]] over the first 2 weeks of life
* Holosystolic [[heart murmur|murmur]] due to the VSD
* Superior axis deviation and [[left ventricular hypertrophy]] (since it must pump blood to both the pulmonary and systemic systems)
* ''normal'' heart size


==Treatment==
==Treatment==
* [[PGE1]] to maintain [[patent ductus arteriosus]]
[[Tricuspid atresia surgery|Surgery]]
* Modified [[Blalock-Taussig]] shunt to maintain pulmonary blood flow by placing a Gortex conduit between the [[subclavian artery]] and the [[pulmonary artery]].
* Cavopulmonary anastomosis (hemi-Fontan or bidirectional Glenn) to provide stable pulmonary flow
* [[Fontan procedure]] to redirect [[inferior vena cava]] and [[hepatic vein]] flow into the pulmonary circulation
