Phenomenon Fenestrations

The fenestration phenomenon is a radiographic manifestation of pericardial constriction pericarditis, which is characterized by a small pulsatile protrusion on the fixed and motionless contour of the cardiac shadow. Constrictive pericarditis occurs when adhesions or structures form around the heart.

Fenestration Phenomenon is a radiographic finding that can be observed in constrictive pericarditis.

The term "Fenestrate" comes from the Latin word "fenestratio", which means creating a window or opening. Thus, the phenomenon of Fenestration is the formation of a small protrusion at the apex of the heart, through which an x-ray beam can pass and be imaged on film.

This phenomenon was first described in 1976 by a scientist named Paul Safran. In his research, he discovered that this phenomenon occurs in patients with constrictive pericarditis, which is when the pericardium - the protective membrane that covers the heart - shrinks around it and leads to obstruction of blood circulation.

With fenestration constriction of the pericardium, typical radiographic signs are observed. One of them is an increase in the "percussion" noise that is heard when the chest is tapped. Another sign is the presence of changes in the contours of the heart. Around a healthy heart the contours are smooth, but with pericardioconstriction the contours become jagged, as if there were small defects or protrusions. The phenomenon of fenestration constrictor is one of the symptoms that can manifest itself in the pericardium.

The phenomenon of Fenestration manifests itself in the form of small protrusions that are located on the periphery of the heart. They can be located
