title: A rare chronic constrictive pericarditis with localized adherent visceral pericardium and normal parietal pericardium: a case report.
abstract: Classic constrictive pericarditis (CP) is characterized by fibrous scarring and adhesion of both the visceral pericardium and the parietal pericardium, which leads to restricted cardiac filling. However, diagnosing CP with normal thickness pericardium and without calcification is still a challenge. The predominant cause in the developed world is idiopathic or viral pericarditis followed by post-cardiac surgery and post-radiation. Tuberculosis still remains a common cause of CP in developing countries. In this report, we describe a rare case of idiopathic localized constrictive visceral pericardium with normal thickness of the parietal pericardium in a middle-aged man. The patient presented with unexplained right heart failure and echocardiography showed moderate bi-atrial enlargement which should be identified with the restrictive cardiomyopathy. After 10 months of conservative treatment, the progression of right heart failure was remaining. A pericardiectomy was performed and the patient recovered. This case serves as a reminder to consider CP in patients with unexplained right heart failure, so that timely investigation and treatment can be initiated.
