perricardium
No, the pericardium is the membrane covering the heart. There is a tough fibrous pericardium and a thin membranous portion called the epicardium. There is a potential space created by these overlying membranes called the pericardial space. The chambers of the heart are the left and right atrium and the left and right ventricles.outside the hear
pleural space
A potential space that contains serous fluid is known as a serous cavity. Examples include the pleural cavity in the chest (between the pleurae surrounding the lungs), the pericardial cavity around the heart, and the peritoneal cavity in the abdomen. These cavities reduce friction between organs and allow them to move smoothly during bodily functions.
In the absence of gravity, the heart doesn't have to work as hard to pump blood around the body, leading to muscle loss and a decrease in size. This phenomenon, known as cardiac atrophy, can cause the heart to "shrink" or lose muscle mass in space.

pericardiectomy
An open space in your body refers to a cavity or an area that is not filled with structures such as organs or tissues. Examples include the sinuses in the skull or the pericardial cavity around the heart.

Heart disease plays a major role in many deaths daily. A coronary angiogram will allow your physician to see your blood vessels in and around the heart to diagnose any potential threats to contracting heart disease.
