Infective endocarditis is an infection of the endocardium. This disease is quite common, especially in people with cardiovascular disease or having cardiovascular intervention. Although the treatment is cured, it can later leave complications of heart valve damage leading to heart failure.

Normally, the aortic valve consists of three thin leaflets that open and close rhythmically according to the heart's activity, allowing blood to flow in one direction from the left ventricle to the aorta. Aortic valve regurgitation is defined as a condition in which the valve does not close tightly, causing some of the blood pumped into the aorta to flow back into the left ventricle.

Cellulitis occurs when the top layer of skin becomes infected with bacteria. Most people with cellulitis can be treated at home, but a few need to be hospitalized for monitoring and treatment. Depending on the severity of the injury, the doctor will prescribe a treatment method.
