| | #REDIREXCT[[Constrictive pericarditis]] |
| *Result of scarring and loss of elasticity of the pericardial sac
| |
| *Typically chronic complication of [[pericarditis]]
| |
| | |
| ==Clinical Features==
| |
| *Pleuritic chest pain
| |
| *Dyspnea
| |
| *Malaise
| |
| *Characteristic symptoms of [[pericarditis]] less frequent in recurrent presentations
| |
| | |
| ==Differential Diagnosis==
| |
| | |
| | |
| ==Evaluation==
| |
| ===Workup===
| |
| *Initial evaluation:
| |
| **ECG: No pathognomonic findings, however may be associated with nonspecific ST and T wave changes, atrial fibrillation, and low voltage <ref> Talreja DR, Edwards WD, Danielson GK, Schaff HV, Tajik AJ, Tazelaar HD, Breen JF, Oh JK. Constrictive pericarditis in 26 patients with histologically normal pericardial thickness. Circulation. 2003 Oct 14;108(15):1852-7. doi: 10.1161/01.CIR.0000087606.18453.FD. Epub 2003 Sep 29. PMID: 14517161.</ref>
| |
| **CXR: Ring of calcification around the heart, however the majority of patients will not have this
| |
| | |
| **TTE
| |
| | |
| *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 <ref> Welch TD. Constrictive pericarditis: diagnosis, management and clinical outcomes. Heart. 2018 May;104(9):725-731. doi: 10.1136/heartjnl-2017-311683. Epub 2017 Nov 25. PMID: 29175978.</ref>
