SCF ENCYCLOPEDIA ENTRY

PERICARDIAL INJURY

Definition

PERICARDIAL INJURY (PI) is a traumatic, iatrogenic, inflammatory, ischemic, or structural disruption of the pericardial sac resulting in compromise of pericardial integrity, altered cardiac containment, impaired cardiac mechanics, hemorrhage, pericardial effusion formation, cardiac tamponade risk, and potential hemodynamic collapse.

The pericardium is a fibroserous structure that surrounds and protects the heart while maintaining optimal cardiac positioning, limiting excessive cardiac dilation, facilitating ventricular interaction, and serving as a protective barrier against infection and trauma. Injury to the pericardium may range from minor contusions and lacerations to complete rupture with cardiac herniation or life-threatening cardiac tamponade.

Within the Synergistic Compatibility Framework (SCF), PERICARDIAL INJURY is classified as a Cardiac Containment Failure and Hemodynamic Regulation Disruption Syndrome, characterized by failure of pericardial structural integrity resulting in impaired cardiac protection, compromised ventricular filling, and systemic circulatory instability.
