XII - Pericardial involvement
Pericardial effusion (w/wo tamponade)
Last update 17/06/2026
Pericarditis (i.e. pericardial inflammation) is usually heralded by acute mediothoracic chest pain (PMID 10878205). Large effusions can be ANA positive and cause pericardial tamponade. When present as a longterm sequela, pericardial thickening may cause restriction and constriction. See also under Vc, d, g, m and XIIk (PMID 20511488, 23376916)
