Overview
Treatment of pericardial effusion depends on the hemodynamic effect of the effusion, suspected underlying cause, effusion size and distribution, and whether there is active pericardial inflammation. Small, uncomplicated effusions may not require immediate intervention and can be monitored clinically and with echocardiography when appropriate. Transthoracic echocardiography is the first-line imaging test to confirm the effusion, estimate its size, assess for cardiac tamponade, and identify a safe route for drainage if needed.
Treatment
Conservative and medical management
- Management should be directed toward the underlying cause whenever it is identified.
- Small, uncomplicated pericardial effusions may be observed with clinical follow-up and echocardiographic surveillance when appropriate.
- Inflammatory pericardial effusion without concern for tamponade is generally treated with anti-inflammatory therapy before drainage is considered.
Role of imaging
- Transthoracic echocardiography is recommended as the first-line imaging modality to evaluate pericardial effusion and assess for cardiac tamponade.
- Cardiac CT, cardiac MRI, or transesophageal echocardiography may be used when transthoracic echocardiography is inconclusive or when secondary causes, loculated effusion, focal tamponade, malignancy, inflammation, or constrictive physiology are suspected.
- Routine cardiac CT or cardiac MRI is not recommended for routine assessment of cardiac tamponade.
Pericardiocentesis and surgical drainage
- Pericardiocentesis is recommended for established or impending cardiac tamponade, particularly in urgent or emergency settings.
- Pericardiocentesis may also be performed for diagnostic purposes when bacterial, tuberculous, or malignant pericardial disease is suspected.
- Routine pericardiocentesis is not recommended for pericardial effusion without tamponade when there is no specific diagnostic or therapeutic indication.
- Pericardiocentesis may be performed through subxiphoid, apical, or parasternal approaches. In emergencies, subxiphoid or apical access is generally preferred; otherwise, the approach should be selected according to the safest and most accessible fluid pocket.
- Echocardiography, fluoroscopy, and/or computed tomography may be used to guide pericardiocentesis.
- Surgical pericardial window may be considered in selected patients with recurrent large pericardial effusion and/or recurrent cardiac tamponade after previous pericardiocentesis.
- Rarely, radical pericardiectomy may be considered for recurrent effusions despite pericardial window, particularly when medically refractory constrictive pericarditis or recurrent pericarditis is also present.[1]
