pericardial disease
Anatomy
- 2-layered (parietal & visceral) tissue sac surrounding heart & proximal great vessels
states
| Signs commonly associated with Kussmaul | Constrictive pericarditis | Restrictive cardiomyopathy | Pericardial tamponade |
|---|---|---|---|
| Kussmaul’s sign | Yes | Yes | No |
| Pulsus paradoxus | Yes | Yes | Yes |
-
Inflammation (w/ or w/o fluid accumulation) → pericarditis
-
Fluid accumulation → effusion ± tamponade
-
Decrease in compliance (sequela of inflammation) → constrictive pericarditis
-
Tamponade and constriction characterized by increased ventricular interdependence 相互依存
Treatment
- Diuresis if intravascular volume overload; surgical pericardiectomy if infectious or advanced
