Dr. Davis emphasizes that valve damage is not only caused by poor dietary habits, explaining, “Diet is often talked about in connection to heart disease, but valve damage has different causes.
Aortic regurgitation (AR), also known as aortic insufficiency (AI), is the leaking of the aortic valve of the heart that causes blood to flow in the reverse direction during ventricular diastole, from the aorta into the left ventricle. As a consequence, the cardiac muscle is forced to work harder than normal.

Significant mitral valve regurgitation has a prevalence of approximately 2% of the population, affecting males and females equally. [26] It is one of the two most common valvular heart diseases in the elderly, [27] and the commonest type of valvular heart disease in low and middle income countries. [3]
Aortic stenosis is most commonly caused by age-related progressive calcific aortic valve disease (CAVD) (>50% of cases), with a mean age of 65 to 70 years. CAVD is the build-up of calcium on the cusps of the valve, and this calcification causes hardening and stenosis of the valve. [ 22 ]
Mitral stenosis is a valvular heart disease characterized by the narrowing of the opening of the mitral valve of the heart. [1] It is almost always caused by rheumatic valvular heart disease. Normally, the mitral valve is about 5 cm 2 during diastole. Any decrease in area below 2 cm 2 causes mitral stenosis. Early diagnosis of mitral stenosis ...
Less than 10% of aortic stenosis is caused by rheumatic heart disease. [15] [16] Rheumatic fever can also cause chronic mitral and aortic regurgitation. [16] While developed countries once had a significant burden of rheumatic fever and rheumatic heart disease, medical advances and improved social conditions have dramatically reduced their ...
However, if a heart valve is damaged, the bacteria can attach themselves to the valve, resulting in infective endocarditis. Additionally, in individuals with weakened immune systems, the concentration of bacteria in the blood can reach levels high enough to increase the probability that some will attach to the valve.
