pericardial effusion
Abnormal accumulation of fluid in the pericardial space, a potential complication of cardiac procedures.
Full Definition
The pathological collection of fluid within the pericardial sac surrounding the heart, which may occur as a complication of percutaneous coronary intervention, particularly following vessel perforation or cardiac tamponade. The condition requires immediate recognition and management as it can progress to hemodynamically significant pericardial tamponade. Diagnosis is typically made by echocardiography, and treatment may range from observation to emergency pericardiocentesis depending on the volume and hemodynamic impact.
Usage
Usage note: Distinguish between hemodynamically significant and insignificant effusions in documentation.
