A cardiac aneurysm is a protrusion of the wall or sinus that occurs as a result of persistent weakening of the pericardial and intimal tissue.
An aneurysm can occur against the background of disturbances in wall tone (atherosclerosis, infections, malignant neoplasms), local disturbances in the elasticity and elasticity of connective tissue (inflammatory or postpartum pericarditis, disturbances in the calcification process, chest trauma). In addition, the cause is irrational drug therapy or general exhaustion of the body.
Depending on the location, right- and left-sided cardiac aneurysms are distinguished. Large and small forms of aneurysms, local and diffuse forms are also distinguished. It is necessary to distinguish between infiltrative, abscessive, serous and gas forms according to the etiology and nature of the course.
