Anatomically single ventricle | single ventricle is defined as the presence of two atrio-ventricular valves with one ventricular chamber or a large dominant ventricle associated with a diminutive opposing ventricle.The term double-inlet ventricle is also used to describe these anomalies |
Tricuspid atresia | atresia of the tricuspid valve, an interatrial communication, and, frequently, hypoplasia of the right ventricle and pulmonary artery. There is a complete absence of the tricuspid valve |
atresia | condition in which a body orifice or passage in the body is abnormally closed or absent |
aortic atresia | absence of the normal valvular opening from the left ventricle of the heart into the aorta. |
mitral atresia | mitral valve is closed off or absent |
Hypoplastic left heart syndrome | the aorta and left ventricle are very small, and the aortic and mitral valves are either too small to allow sufficient blood flow or are atretic (closed) altogether. |
functionally single ventricle | refer to anatomically single ventricle |
