Pericardial constriction causes

Causes
Constrictive pericarditis is most commonly caused by conditions or events that cause inflammation to develop around the heart, including:


 * Coronary artery bypass graft surgery: In patients who have undergone coronary artery bypass surgery with pericardial sparing, there is danger of tearing a bypass graft while removing the pericardium. If any pericardium is not removed, it is possible for bands of pericardium to cause localized constriction which may cause symptoms and signs consistent with constriction.
 * Radiation therapy to the chest
 * Tuberculosis
 * Post Viral Pericarditis
 * Postsurgical
 * Prior mediastinal radiation therapy
 * Chronic Renal Failure
 * Connective Tissue Disorders
 * Neoplastic pericardial infiltration
 * Incomplete drainage of purulent pericarditis
 * Fungal and Parasitic Infections
 * Following pericarditis associated with ST elevation myocardial infarction (Dressler's syndrome)
 * In Association with pulmonary asbestosis
 * Mesothelioma
 * Bacterial, viral, or surgical infections that cause abnormal buildup in the covering of the heart
