The pericardium is a thin sac that surrounds your heart. It protects and lubricates your heart and keeps it in place within your chest.
What is the function of the pericardium?
The pericardium acts as mechanical protection for the heart and big vessels, and a lubrication to reduce friction between the heart and the surrounding structures. A very important role in all aspects of pericardial functions is played by mesothelial cells.
Where is the parietal pericardium located?
Parietal pericardium: The outer layer of the pericardium which is a conical sac of fibrous tissue that surrounds the heart and the roots of the great blood vessels.
Is pericardium a layer of the heart?
The Pericardium. The pericardium is the fibrous sac that surrounds the heart. It can be divided into three layers, the fibrous pericardium, the parietal pericardium, and the visceral pericardium. The parietal and visceral pericardia together form the serous pericardium.
Is the pericardium part of the heart wall?
The more delicate serous pericardium consists of two layers: the parietal pericardium, which is fused to the fibrous pericardium, and an inner visceral pericardium, or epicardium, which is fused to the heart and is part of the heart wall.

What fluid is in the pericardium?
Pericardial fluid is the serous fluid secreted by the serous layer of the pericardium into the pericardial cavity. The pericardium consists of two layers, an outer fibrous layer and the inner serous layer.
What are the layers of pericardium?
The pericardium consists of two layers: the fibrous and the serous. The fibrous pericardium is a conical-shaped sac. Its apex is fused with the roots of the great vessels at the base of the heart. Its broad base overlies the central fibrous area of the diaphragm with which it is fused.
Do pericardial cysts grow?
In principle, a pericardial cyst only requires follow-up, however, growing cases or symptomatic cases require surgical removal. This report herein presents a rare case of rapidly growing giant pericardial cyst 20 years following its detection.
What is the pericardial?
The pericardium is a thin, two-layered, fluid-filled sac that covers the outer surface of the heart. It provides lubrication for the heart, shields the heart from infection and malignancy, and contains the heart in the chest wall.
What is fibrous pericardium?
The fibrous pericardium is the outer layer and holds the heart in place and protect it from surrounding infections. It is composed of thick connective tissue. The serous pericardium has two layers, the visceral and parietal layers.
What is the pericardial sac lined with?
The pericardium, also called pericardial sac, is a double-walled sac containing the heart and the roots of the great vessels. It has two layers, an outer layer made of strong connective tissue (fibrous pericardium), and an inner layer made of serous membrane (serous pericardium).
What is the deepest pericardial layer?
The visceral serous pericardium, or epicardium, is the deeper of the two layers of the serous pericardium. It is a mesothelial sheet that lies superficial and closely adherent to the surface of the heart.
What is pericardial membrane?
Summary. The pericardium is a membrane, or sac, that surrounds your heart. It holds the heart in place and helps it work properly. Problems with the pericardium include. Pericarditis - an inflammation of the sac.
Can you live without the pericardium?
Can the heart function normally without a pericardium? The pericardium is not essential for normal heart function. In patients with pericarditis, the pericardium already has lost its lubricating ability so removing it does not make that situation worse.
Where is the SA node located?
An electrical stimulus is generated by the sinus node (also called the sinoatrial node, or SA node). This is a small mass of specialized tissue located in the right upper chamber (atria) of the heart.
What holds your heart in place?
Pericardium, the sac that surrounds your heart. Made of thin layers of tissue, it holds the heart in place and protects it. A small amount of fluid between the layers helps reduce friction between the beating heart and surrounding tissues.
What are the 4 signs your heart is quietly failing?
Heart failure signs and symptoms may include: Shortness of breath with activity or when lying down. Fatigue and weakness. Swelling in the legs, ankles and feet.
What happens if the pericardium is damaged?
The pericardium has two layers. The space between the layers normally contains a thin layer of fluid. But if the pericardium is diseased or injured, the resulting inflammation can lead to excess fluid. Fluid can also build up around the heart without inflammation, such as from bleeding after a chest trauma.
What is the most common cause of pericardial effusion?
Lung cancer is the most common cause of the malignant pericardial effusion. Trauma: Blunt, penetrating, and iatrogenic injury to the myocardium, aorta, or coronary vessels can lead to the accumulation of blood within the pericardial sac.
What are the symptoms of a pericardial cyst?
Although pericardial cysts are usually asymptomatic, symptoms can occur from compression of surrounding mediastinal structures, as in our patient. Other common symptoms, in decreasing order, include chest pain, dyspnea, persistent cough, and persistent atrial tachycardia.
What is the treatment for a pericardial cyst?
Among patients who have a symptomatic pericardial cyst, a cyst resection with either a thoracotomy or video-assisted thoracoscopic surgery has been the most favoured approach4 (Table 2).
What can happen if a cyst is left untreated?
Some cysts are cancerous and early treatment is vital. If left untreated, benign cysts can cause serious complications including: Infection – the cyst fills with bacteria and pus, and becomes an abscess. If the abscess bursts inside the body, there is a risk of blood poisoning (septicaemia).
Does the pericardium have lymphatic drainage?
The lymphatics draining the lateral parts of pericardium pass to the anterior mediastinal, tracheobronchial, lateropericardial, prepericardial and posterior mediastinal (juxtaesophageal) lymph nodes. The posterior part of the pericardium drains to the juxtaesophageal and tracheobronchial nodes.
What is the pericardium made of?
The pericardium is a simple structure composed of connective tissue lined by a single layer of mesothelial cells that encases the heart. The mesothelial cells secrete mucopolysaccharide, which lubricates the pericardium, allowing the heart to expand and contract with limited resistance.
What are pericardial sinuses?
From Wikipedia, the free encyclopedia. The pericardial sinuses are impressions in the pericardial sac formed between the points where great vessels enter it. Pericardial sinus. Posterior wall of the pericardial sac, showing the lines of reflection of the serous pericardium on the great vessels. (
