Pericarditis is an inflammation of the pericardium, which is a thin, two-layered, fluid-filled sac that covers the outer surface of the heart. It shields the heart from infection or malignancy and contains the heart in the chest wall. It also prevents the heart from over-expanding when blood volume increases, which keeps the heart functioning efficiently. Pericarditis develops suddenly and may last up to several months. If you could see and touch it, the membrane around the heart would look red and swollen, like the skin around a cut that becomes inflamed. Sometimes excess fluid develops in the space between the pericardial layers and causes a pericardial effusion (buildup of excess fluid around the heart). Pericardial effusion can cause cardiac tamponade, a severe compression of the heart that impairs its ability to function, and can be life threatening.
Take this opportunity to learn more about the symptoms and treatment options of pericarditis and have your questions by Dr. Allan Klein and Dr. Douglas Johnston from the Cleveland Clinic.
