"An imprisoned heart" arrested by pillory of calcified ring surrounding both ventricles: An extremely rare case of constrictive pericarditis.

We report the case of a 63-year-old man who was admitted to our hospital due to progressive dyspnea and leg edema. Echocardiography and cardiac computed tomography revealed localized severe pericardial calcification surrounding the basal segments of both ventricles, which caused pericardial constriction. Right heart catheter examination confirmed typical hemodynamic findings of constrictive pericarditis and subsequently led to the definite diagnosis of constrictive pericarditis. We experienced a rare case of localized constrictive pericarditis caused by the thickened and calcified pericardial ring. Non-invasive and invasive multimodality evaluations should be encouraged for accurate diagnosis and better management of these cases.
