Pericardium

The pericardium is the lining that surrounds and protects the most vital organ in a person's body, the heart. This fluid filled sac serves many purposes for the heart. There are certain instances where blood levels increase in the heart and the pericardium keep it from expanding. One of the main functions of the pericardium is to decrease the amount of friction that could be caused if there is a lack of lubrication. There are two coats that make up the pericardium. The internal coat (also known as the parietal) is the tough portion that is attached to the central part of the diaphragm. Whereas the second layer (visceral pericardium) is the closest portion to the heart. Between these two layers is the fluid that keeps friction low. Movement of the heart is normal and if levels of lubrication remain constant, there is a healthy amount of flow within the chest.

There are certain diseases that could disrupt the normal function of the pericardium for its protection of the heart. One of the most serious complications is mesothelioma cancer that affects the pericardium. Mesothelioma is caused my exposure to asbestos particles that have become airborne. Some of these particles can be lodged into certain areas of the body such as the lungs and make its way into heart cavities. Once the particles are lodged, they create scar tissue that after many years turns into cancerous cells. Pericardium difficulties are very serious because scar tissue inhibits lubrication to be created through the portions of the heart cavity, causing friction to surrounding areas. The heart also can be bombarded with excess fluid that causes swelling, discomfort, and heart irregularities. Unfortunately, doctors find this type or mesothelioma cancer in its later stages. Therefore,mesothelioma treatment and recovery is less receptive by the patient. Through research and new medical studies, doctors are trying to find new ways to diagnose and treat pericardial mesothelioma in earlier stages.
