Overview
Medical therapy alone is not definitive treatment for cardiac tamponade. When cardiac tamponade is established or impending, urgent drainage with pericardiocentesis is recommended, particularly in urgent or emergency settings. Transthoracic echocardiography is recommended to identify pericardial effusion, assess for tamponade physiology, and help guide management.
Treatment
- Cardiac tamponade requires prompt clinical and echocardiographic assessment because hemodynamic compromise depends on the rate of pericardial fluid accumulation as well as the amount of fluid.
- Transthoracic echocardiography is recommended to identify pericardial effusion and assess for cardiac tamponade.
- Clinical correlation with symptoms, heart rate, and blood pressure is essential when tamponade is suspected.
- Pericardiocentesis is recommended for established or impending cardiac tamponade, especially in urgent or emergency settings.
- Echocardiography, fluoroscopy, and/or computed tomography may be used to guide pericardiocentesis.
- Cardiac CT or cardiac MRI is not recommended for routine assessment of cardiac tamponade.
- In patients with inflammatory pericardial effusion without concern for tamponade, anti-inflammatory therapy should generally be pursued before pericardiocentesis.[1]
- Diuretics and vasodilators should generally be avoided in patients with cardiac tamponade because they may worsen hemodynamic compromise by reducing preload.[2]
Role of imaging
- A dilated inferior vena cava with minimal or absent respiratory variation is a sensitive screening feature for tamponade but does not confirm the diagnosis by itself.
- Diastolic right ventricular collapse is a specific echocardiographic finding of cardiac tamponade.
- Right atrial inversion lasting beyond one-third of the cardiac cycle and marked respiratory variation in mitral and tricuspid inflow velocities are also echocardiographic features of tamponade.[1]
