Artificial (mechanical) heart valve

Valvular heart disease is a process involving one or more of the valves of the heart: the aortic and mitral valves on the left and the pulmonary and tricuspid valves on the right. Valve problems may be congenital (inborn) or acquired (due to another cause later in life). Often (depending on the severity) involves valve repair or replacement (insertion of an artificial heart valve).

Mechanical heart valves (MHV) are prosthetics designed to replicate the function of the natural valves of the human heart. MHV are very reliable and allow the patient to live a normal life. Most MHV last for at least 20 to 30 years. There are three major types of mechanical valves - caged-ball, tilting-disk and bileaflet - with many modifications on these designs. All MHV function in the human body creating a unique sound effects and vibration. These phenomena are the causes of the syndrome, believed to be the authors of the Handbook Clinical Psychiatry. Due to the disruption of the receptors in the area of the implant and due to the cardiac dysrhythmia the attention of the patient focuses on the activities of his own heart. The syndrome, wrote the authors, often occurs when implantation prosthesis of the mitral valve or when replacing a few valves at once.[1][2][3]
