Detailed explanation-1: -The three types of heart valve diseases are regurgitation, stenosis, and atresia. The type of heart valve disease you have depends on which valve is affected and in what way. Heart valve diseases can cause problems in any of the heart’s four valves: the aortic, mitral, pulmonary, and tricuspid valves.
Detailed explanation-2: -Both the pulmonary and aortic valves are audible in the second intercostal space. The only difference is that the aortic valve is heard in the right second intercostal space at the upper right sternal edge, while the pulmonary valve is auscultated in the left second intercostal space at the upper left sternal edge.
Detailed explanation-3: -Blood passes through a valve before leaving each chamber of the heart. The valves prevent the backward flow of blood. Valves are actually flaps (leaflets) that act as one-way inlets for blood coming into a ventricle and one-way outlets for blood leaving a ventricle.
