Background[1]
- Occurs when normally elastic pericardium becomes thickened and fibrotic (i.e., loss of elasticiticty)
- Can be infectious, post-cardiac surgery, inflammatory, idiopathic or related to radiation exposure
- Impairs diastolic filling of heart
- Must distinguish from restrictive cardiomyopathy
- Typically chronic complication of pericarditis
Clinical Features
- Pleuritic chest pain
- Malaise
- Symptoms similar to congestive heart failure, especially right sided
- Dyspnea
- Lower extremity edema
- Jugular venous distention
- Characteristic symptoms of pericarditis less frequent in recurrent presentations
Differential Diagnosis
Cardiomyopathy
- Dilated cardiomyopathy
- Hypertrophic cardiomyopathy
- Restrictive cardiomyopathy
- Peripartum cardiomyopathy
- Takotsubo cardiomyopathy
- Arrhythmogenic right ventricular dysplasia
Congestive heart failure
- Cardiovascular
- Pulmonary
- Other
- Pure volume overload
- Renal failure
- Post-Transfusion
- Sepsis
- Anaphylaxis
- Pure volume overload
Evaluation
Workup
Initial evaluation:
- CBC
- Chemistry
- ECG
- No pathognomonic findings, however may be associated with nonspecific ST and T wave changes, atrial fibrillation, and low voltage [2]
- CXR
- Ring of calcification around the heart, however the majority of patients will not have this
- Troponin/CK
- BNP
- Ultrasound
- Formal TTE/TEE
Advanced evaluation
- Cardiac CT/MR
- Invasive hemodynamic evaluation
Diagnosis
- No single diagnostic imaging/evaluation parameter
- Must be differentiated from tamponade and disorders such as restrictive cardiomyopathy as management is different for each of these pathologies
Management
- If no signs of chronic process: Medical management (Colchicine, NSAIDs for 2-3 months)
- Chronic signs: Anasarca, cachexia, atrial fibrillation, hepatic dysfunction, pericardial calcification
- If chronic process: Pericardiectomy [3]
- Definitive treatment is surgical pericardiectomy
Disposition
- Admit
