Constrictive pericarditis after heart transplantation: a case report

Background Constrictive pericarditis (CP) is a disease characterized by inflammation, progressive fibrosis, and thickening of the pericardium. Constrictive pericarditis after heart transplantation (HT) is a rare phenomenon, with a reported incidence of 1.4-3.9%. It is an important clinical problem which shares similar clinical features with entities such as restrictive cardiomyopathy. Therefore, it poses diagnostic challenges and therapeutic dilemmas even for experienced clinicians. Case summary A 53-year-old patient developed a zoster infection with pericardial effusion 9 months after HT for idiopathic dilated cardiomyopathy. Two months later, he presented with leg oedema and ascites and was treated by diuretics for volume overload. He was readmitted 8 months later with features of right heart failure. Multimodal imaging investigations were suggestive of CP. He successfully recovered after a radical pericardiectomy. Discussion Constrictive pericarditis is a rare complication in HT. Heart transplant recipients (HTR) with a history of post-operative pericardial effusion, or with rejection episodes are at high risk of developing CP. Differentiating CP from other conditions that cause apparent congestive heart failure in HTR is challenging. Management of CP is mainly surgical pericardiectomy.
