pericardial effusion
Abnormal accumulation of fluid in the pericardial space that may cause hemodynamic compromise following cardiac surgery.
Full Definition
Pericardial effusion in the postoperative cardiac surgery setting involves accumulation of blood, serous fluid, or both in the pericardial space. This complication can develop gradually or acutely and may progress to cardiac tamponade if significant. Clinical presentation includes elevated filling pressures, equalization of diastolic pressures, and hemodynamic instability. Diagnosis is confirmed by echocardiography showing pericardial fluid accumulation and signs of chamber compression. Management ranges from observation for small effusions to urgent pericardiocentesis or surgical drainage for hemodynamically significant collections.
Usage
Usage note: Specify hemodynamic significance and location (anterior, posterior, circumferential) when relevant.
