Constrictive pericarditis refers to inflammation of the pericardial sac, possibly leading to acute heart failure. More than 80% cases are presumed to be due to recent or remote viral illnesses. Prominent features include chest pain, dyspnea and electrocardiogram (ECG) revealing P-R segment depression, diffuse concave ST segment elevation, and T-wave inversion. Echocardiogram and cardiac magnetic resonance imaging (MRI) can help establish diagnosis. Over time, the pericardium can undergo fibrosis or calcification resulting in excessive symptoms. After medical management with ibuprofen, colchicine or steroids, partial or complete pericardiectomy is considered. We are presenting a case with constrictive pericarditis due to extensive pericardial calcification, and ultimate resolution with pericardiectomy.
