Answer :
C. Cardiac tamponade
The pericardium, the sac that encircles the heart, becomes inflamed when it has pericarditis. The pericardium's regular roles include protecting the heart and reducing friction between the organs that surround it.
Pericardial effusion, or fluid buildup in the pericardial sac, can occur in conjunction with pericarditis. The condition known as cardiac tamponade occurs when there is an excessive buildup of fluid in the pericardium, which can compress or restrict the heart. When left untreated, cardiac tamponade is a dangerous ailment that poses a risk to one's life.
Pericardial effusion and cardiac tamponade can result from the inflammatory process of pericarditis, which can also cause fluid to build up in the pericardial sac.
