This congenital heart disease consists of the displacement of the tricuspid valve and a malformation of its flaps, which causes a minor or major dysfunction, depending on the case, causing blood leaks that reduce cardiac function increasing the size of the heart and eventually failure.
Its origin is unknown, but its degree of involvement is variable. In some cases, the valve is slightly deviated and the malformation is minor, causing mild symptoms, but in others, there is a severe malformation that causes large blood leaks.
This condition can lead to other serious heart conditions, such as arrhythmias, holes in the heart tissue, and Wolff-Parkinson-White syndrome.
There are no certainties about the risk factors for developing this anomaly, but family history, environment, and the intake of drugs during pregnancy are considered possible. On this last point, it has been established that lithium can increase the chances of this deformation in the fetus.
This condition usually leads to the following complications:
- Heart attack.
- Heart failure.
