The study found that 24 percent of the patients had been misdiagnosed: 22 patients previously diagnosed with epilepsy were found to have nonepileptic seizures, and four patients previously diagnosed with nonepileptic seizures were found to have epileptic seizures.
The purpose of valves is to prevent back flow of blood. In other words, it ensures that blood flows only in one direction . An atrioventricular (AV) valve is a valve located in the heart between the atria and the ventricles. In the right side of the heart, the AV valve is called the tricuspid valve . On the left side of the heart, the AV valve is called the mitral valve .
The heart has four valves that separate each chamber so that, under normal conditions, blood cannot flow backwards. These valves can sometimes be replaced if they become damaged. The heartâs valves are: Tricuspid (right AV) valve: This valve opens to allow blood to flow from the right atrium to the right ventricle.
