What intervention is performed to alleviate the effects of pericarditis?

Pericardiocentesis is performed to alleviate the effects of pericarditis, particularly when there is an accumulation of fluid in the pericardial space, which can exert pressure on the heart and hinder its ability to function properly. This procedure involves inserting a needle into the pericardial sac to remove excess fluid, thus reducing pressure on the heart and improving cardiac output.

Pericarditis, often resulting from inflammation, infection, or other underlying conditions, can lead to symptoms such as chest pain and difficulty breathing. The aim of pericardiocentesis is not just to relieve these symptoms, but also to provide diagnostic information about the nature of the fluid, which can guide further treatment decisions.

Other interventions such as coronary artery bypass, pacing therapy, or heart valve replacement are treatments for different cardiac conditions and are not directly relevant to managing pericarditis. They address issues related to coronary artery disease, arrhythmias, or valvular heart diseases, respectively, rather than the complications arising specifically from pericardial inflammation or fluid accumulation.
