Detailed explanation-1: -Previous research has suggested that the mechanism involved in the link between blood pressure and AVD could be that higher blood pressure can cause cell damage leading to a loss of elasticity in the aorta and stiffening of the aortic valve.
Detailed explanation-2: -Heart valve problems may include a narrowed valve (stenosis), a leaking valve (regurgitation) or a valve with leaflets that are bulging back (prolapse), as shown in the bottom two images. Normal heart valves and blood flow are shown in the top image.
Detailed explanation-3: -tricuspid valve: located between the right atrium and the right ventricle. pulmonary valve: located between the right ventricle and the pulmonary artery. mitral valve: located between the left atrium and the left ventricle. aortic valve: located between the left ventricle and the aorta.
