What is a pericardial fat pad?

Pericardial fat pads are normal structures that lie in the cardiophrenic angle. They are adipose tissues surrounding the heart composed of the epicardial fat, which lies between the myocardium and visceral pericardium, and paracardial fat, which is adherent and external to the parietal pericardium.

What is the fat around heart?

Epicardial fat covers 80% of the heart’s surface and constitutes 20% of total heart weight. It is present along the distribution of the coronary arteries, over the right ventricle especially along the right border, anterior surface and at the apex.

How do I reduce pericardial fat?

Aerobic exercise and resistance training with weights are both effective in reducing epicardial fat mass in individuals with abdominal obesity, but resistance training appears to be a better exercise for reducing pericardial adipose tissue mass, according to the results of a new study.

What is a fat pad on the lung?

The floating cardiac fat pad sign occurs when pleural air collects anteriorly and superiorly in the most non-dependent portion of the chest lifting the pericardial fat pad off the diaphragm. Lung markings are still seen surrounding the pericardial fat pad due to the inflated lower lobe of the lung resting dependently.

Where is pericardial fat located?

Pericardial fat is fatty tissue that is adjacent to the heart. The heart is centrally located in the chest with a portion extending into the left side of the chest. Therefore, if there is pericardial fat, it is often located in the lower portion fo the chest adjacent to the heart, not really in the lower left lung.

What is the function of pericardial fat?

Under physiological conditions, epicardial fat protects and supports the heart to exert its normal function. Many clinical studies have shown significant associations between increased amounts of epicardial fat and coronary artery disease (CAD).

How do you measure pericardial fat?

Epicardial fat thickness is measured during end-systole at the point on the free wall of the right ventricle along the midline of the ultrasound beam, with the best effort to be perpendicular to the aortic annulus, used as an anatomic landmark.

What causes fatty heart?

A buildup of fatty plaques in your arteries (atherosclerosis) is the most common cause of coronary artery disease. Unhealthy lifestyle habits, such as a poor diet, lack of exercise, being overweight and smoking, can lead to atherosclerosis.

What is a fat pad?

A fat pad (aka haversian gland) is a mass of closely packed fat cells surrounded by fibrous tissue septa. They may be extensively supplied with capillaries and nerve endings. Examples are: Intraarticular fat pads. These are also covered by a layer of synovial cells.

Where are the pericardial fat pads located in the heart?

Pericardial fat pads. They are adipose tissues surrounding the heart composed of the epicardial fat, which lies between the myocardium and visceral pericardium, and paracardial fat, which is adherent and external to the parietal pericardium. Unsurprisingly, they are more prominent in obese patients.

Is the epicardial fat pad sign a normal finding?

Pericardial cyst. The epicardial fat pad described here is a normal finding. The epicardial fat pad sign (pericardial fat pad sign, fat pad sign) is an abnormal finding that can be seen with pericardial effusion Curvilinear fat density in displaced posteriorly from sternum on lateral chest radiograph.

Can a fat pad simulate a cardiophrenic angle?

A prominent pericardial fat pad may simulate a cardiophrenic angle mass. Large pericardial fat pads are often seen in obese patients, in patients receiving exogenous steroid therapy, and in patients with Cushing’s syndrome.

How does pericardial fat affect the development of POAF?

Pericardial fat is autonomically innervated and highly metabolically active, allowing it to act as an important source of several adipokines and cytokines that can impact the development of POAF [58, 59]. A prominent pericardial fat pad may simulate a cardiophrenic angle mass.
