In patients with chronic aortic valve insufficiency, a diminished first heart sound may be heard, and a diminished or absent second heart sound may be heard in the aortic valve region. A sighing murmur may be heard in the aortic valve region during diastole, and in severe cases, a mid-systolic murmur is often heard in the aortic valve region. In acute cases, the first heart sound is weakened or absent, and in pulmonary hypertension, the second heart sound in the pulmonary valve area is hyperactive, and the pathologic third and fourth heart sounds are often heard. Lung auscultation can be heard rales, or in the bottom of the lungs can be heard small blisters, the condition of the severe lungs full of blisters. A diastolic murmur with peripheral vascular signs typical of aortic valve insufficiency is diagnostic, and an echocardiogram confirms the diagnosis. If there is any discomfort, it is recommended to go to the hospital for treatment in time to avoid delay.
