Tricuspid atresia

In 1987, Kreysig first clearly described the anatomical features of cardiac tricuspid atresia, that is, the lack of direct communication between the right ventricle and the right atrium. In 1861, Schuberg first applied the term tricuspia atresia to describe this malformation. Although several cases were reported in the English literature of the 19th century, Hess officially adopted the term tricuspid atresia in the literature until 1917. In 1906, Kuhen reported that the aorta in patients with tricuspid atresia can be normal or translocated. Tricuspid atresia is a type of cyanotic congenital heart disease, which accounts for about 1 to 5% of congenital heart disease. Ranked third after cyanotic congenital heart disease relay tetralogy and aortic dislocation. The main pathological changes are tricuspid valve atresia or loss of tricuspid valve orifice, oblong foramen ovale or atrial septal defect, mitral and left ventricular hypertrophy, and right ventricular hypoplasia.
