Combinational elastography prior to pericardiectomy to assess liver condition in patients with constrictive pericarditis

A 68-year-old man was diagnosed with pericarditis associated with immunoglobulin G4-related disease and was administered prednisolone 2 years prior to presentation. During the process of tapering off from prednisolone 1 year later, edema of the lower legs and pleural effusion worsened. He gradually developed dyspnea on exertion, and laboratory examinations revealed elevated liver enzyme levels. Diuretics were administered; however, the symptoms did not resolve. Transthoracic echocardiography and cardiac catheterization revealed findings consistent with those of constrictive pericarditis. Pericardiectomy was considered and the perioperative risks due to possible recovery from liver dysfunction were discussed. Combinational elastography was subsequently performed. The results indicated the absence of liver fibrosis, suggesting that liver dysfunction was attributable to liver congestion; thus, the liver dysfunction was considered reversible. Subsequently, pericardiectomy was performed. Given that constrictive pericarditis can lead to liver dysfunction due to congestion, the perioperative risk is often controversial when considering surgical interventions.

Learning objective

Combinational elastography may be useful in the preoperative evaluation of patients with cardiac diseases complicated by liver dysfunction to distinguish liver fibrosis, understand the pathogenesis of liver dysfunction, and determine subsequent treatment strategies.
