Effusive-Constrictive Pericarditis.

Effusive-constrictive pericarditis (ECP) corresponds to the coexistence of a hemodynamically significant pericardial effusion and decreased pericardial compliance. The hallmark of ECP is the persistence of elevated right atrial pressure postpericardiocentesis. The prevalence of ECP seems higher in tuberculous pericarditis and lower in idiopathic cases. The diagnosis of ECP is traditionally based on invasive hemodynamics but the presence of echocardiographic features of constrictive pericarditis post-pericardiocentesisis can also identify ECP. Data on the prognosis and optimal treatment of ECP are still limited. Anti-inflammatory agents should be the first line of treatment. Pericardiectomy should be reserved for refractory cases.
