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 mitral valve is made up of the annulus, anterior and posterior leaflets, and chordae, which attach the leaflets to their respective papillary muscles. A normally functioning valve allows blood to flow unimpeded from the left atrium to the left ventricle during diastole and prevents regurgitation during systole.Normal mitral valve function is dependent not only on the integrity of the underlying valvular structure, but on that of the adjacent myocardium as well. normally functioning valve allows blood to flow unimpeded from the left atrium to the left ventricle during diastole and prevents regurgitation during systole.
