Tricuspid valve

The tricuspid valve is shifted to the right ventricle, mainly the septum and posterior valve leaflets. It is often attached to the right ventricular wall near the apex of the heart instead of the fibrous annulus of the tricuspid valve. The ventricle is divided into two cavities. The wall of the ventricle above the malformed valve is thin and connects with the right atrium to form a large heart cavity. It is called "atrialized right ventricle" and has the same function as the right atrium. The heart cavity below the malformed valve includes The apex and outflow tract are "functional right ventricles," which function the same as normal right ventricles, but with a relatively small heart cavity. Often accompanied by atrial septal defect, ventricular septal defect, open ductus arteriosus, pulmonary artery stenosis or atresia. Increased right atrial pressure may occur, and at this time, if there is an atrial septal defect or an oval opening, it can cause right-to-left shunts and cyanosis.
