new-onset liver failure: pitfalls of an unusual diagnosis

introduction heart failure is the second most common cause of ascites after cirrhosis. there are cardiac and noncardiac etiologies of ascites, and the multimodality imaging approach is a rich tool to redefine the final diagnosis. case presentation we present a case-series where 3 patients were referred to our hospital for further hepatology assessment due to severe abdominal ascites and liver failure. constrictive pericarditis was diagnosed in all of them. nowadays, constrictive pericarditis is a well-known disease, but sometimes its clinical presentation may delay the treatment and worsen the prognosis. our 3 cases had similar clinical scenarios and hemodynamic patterns when undergoing right-heart catheterization, but they had different anatomical pericardium-compromise, requiring different surgical strategies. conclusions nowadays, multimodality imaging, especially cardiac magnetic resonance imaging and cardiac computed tomography, allows us to study a wide spectrum of the same disease in terms of anatomical compromise and cardiac physiology in order to stratify different prognosis and treatment options. we describe 3 unusual clinical cases where the initial differential diagnosis denoted noncardiac etiologies. the level of serum nt-probnp proved pivotal to the redefinition of the clinical scenario and differentiation between the cardiac and noncardiac etiologies of new-onset ascites. a multidisciplinary approach in this setting between internists, hepatologists, and cardiologists was helpful to establish the final diagnosis in all the patients.
