"Pericardial flare" associated with immunoglobulin G4-related disease: A case report - rapid transition from cardiac tamponade to effusive constrictive pericarditis.

ABSTRACT: Immunoglobulin G4-related disease (IgG4-RD) has recently been recognized as a systemic fibroinflammatory disease characterized by IgG4-positive lymphoplasmacytic infiltration. Despite the increased awareness of this disease category, cardiovascular involvement has rarely been reported. An 83-year-old man was admitted because of a moderate amount of pericardial effusion concomitant with bilateral pleural effusion. Despite aggressive heart failure therapy, pericardial effusion increased. He underwent pericardial drainage, and heart failure symptoms significantly improved. After only 1 month, right-sided heart failure with re-accumulation of pericardial fluid recurred, although the results of cardiac catheter examination were not indicative of constrictive pericarditis. Despite the aggressive medication, he developed weight gain and pleural effusion 6 months after pericardial drainage. Based on multimodal hemodynamic and morphological evaluations, he was finally diagnosed with effusive constrictive pericarditis and underwent total pericardiectomy. Based on histopathological findings, the final diagnosis was established as IgG4-RD associated constrictive pericarditis. We report an extremely rare case of IgG4-RD associated pericardial involvement, in which rapid transition from cardiac tamponade to effusive constrictive pericarditis was confirmed. Diagnostic work-up for constrictive pericarditis requires a high index of suspicion. Increased recognition of IgG4-RD associated pericardial involvement could potentially mitigate morbidity and might contribute to improved patient outcomes. <Learning objective: Immunoglobulin G4-related disease (IgG4-RD) is a systemic inflammatory disease characterized by chronic IgG4-positive lymphocyte infiltration that causes fibrosclerotic changes in various tissues and organs. Detailed serial multimodal imaging and physical examination contribute to the recognition of latent constrictive physiology and clinical decision-making. Increased recognition of IgG4-RD associated pericardial involvement could lead to early diagnosis and might contribute to improved patient outcomes.>.

Project description:BackgroundPurulent bacterial pericarditis (PBP) is a highly lethal infection of the pericardial space that arises as a complication of infective illnesses. Purulent bacterial pericarditis remains a diagnostic challenge given its non-specific clinical and investigative features and carries exceedingly high mortality rates due to fulminant sepsis and morbidity including constrictive pericarditis in survivors. We present our management of cardiac tamponade and subsequent constrictive pericarditis due to Actinomyces meyeri PBP.Case summaryA 53-year-old Caucasian male presented with acute New York Heart Association Class IV dyspnoea and chest discomfort, in the context of multiple hospital presentations over the preceding 8 weeks due to presumed recurrent viral pericarditis. On this admission, initial transthoracic echocardiography (TTE) demonstrated a large asymmetric pericardial effusion for which he underwent urgent pericardiocentesis. Serial TTE post-pericardiocentesis, however, demonstrated effusion re-accumulation and effusive-constrictive pericarditis, confirmed on cardiac magnetic resonance imaging. Fluid culture was positive for A. meyeri. He was diagnosed with PBP, but his condition deteriorated despite appropriate intravenous antibiotic therapy, necessitating semi-urgent surgical pericardiectomy. He recovered well and was discharged on Day 10 post-operatively.DiscussionUnlike uncomplicated acute viral or idiopathic pericarditis, PBP portends a very poor prognosis if unrecognized and untreated. Diagnostic challenges persist given its rarity in modern clinical practice; however, PBP should be considered in cases of seemingly recurrent pericarditis. Multi-modal cardiac imaging and careful analysis of pericardial fluid including cultures and lactate dehydrogenase/serum ratios may assist in earlier recognition. In this case, source control and symptom relief were achieved only with combined intravenous antibiotics, surgical evacuation, and pericardiectomy.
