Pericardiocentesis is a medical procedure involving the extraction of fluid from the pericardial cavity, the space surrounding the heart. It is primarily performed to diagnose or treat pericardial effusion, which is the accumulation of excess fluid in this area. This condition can result from various causes, including infections, malignancies, trauma, or inflammatory diseases, and may lead to cardiac tamponade, a life-threatening compression of the heart.

The procedure typically involves the insertion of a needle and a catheter into the pericardial space, usually via a subxiphoid approach, though other techniques such as parasternal or apical approaches may be employed based on clinical considerations. Pericardiocentesis is often performed under echocardiographic guidance to enhance safety and accuracy.

Indications for pericardiocentesis include the presence of large or symptomatic pericardial effusions, particularly when cardiac tamponade is suspected. It can also be used diagnostically to analyze pericardial fluid for infectious, malignant, or inflammatory causes.

Complications are relatively rare but can include puncture of coronary arteries or cardiac structures, pneumothorax, arrhythmias, or infection. The procedure requires performed by trained medical professionals with appropriate imaging support.

Overall, pericardiocentesis is a vital intervention in managing pericardial diseases, providing both diagnostic information and potential relief of hemodynamic compromise caused by fluid accumulation around the heart.
