New directions in diagnosis and treatment of pericardial disease. A project of the Taskforce on Pericardial Disease of the World Heart Federation.

New directions in the diagnosis and treatment of pericardial diseases synthesize the achievements of modern imaging with molecular biology and immunology techniques. Comprehensive and systematic implementation of new techniques of pericardiocentesis, pericardial fluid analysis, pericardioscopy, epicardial and pericardial biopsy, as well the application of comprehensive molecular biology and immunology techniques for pericardial fluid and biopsy analyses have opened new windows to the pericardial diseases, permitting early specific diagnosis and creating foundations for etiologic treatment in many cases. In patients with recurrent pericarditis, resistant to conventional treatments, as well as in patients with neoplastic pericarditis an alternative intrapericardial treatment regimen was suggested by the Taskforce on Pericardial Diseases of the World Heart Federation. Intrapericardial application of medication avoids systemic side effects with increased local efficacy. The following protocols are proposed: CIRP (colchicine in recurrent pericarditis)--colchicine vs placebo in chronic/recurring pericarditis without pericardiocentesis; TRIPE (triamcinolone in pericardial effusion)--intrapericardial instillation of triamcinolone + 6 months colchicine vs pericardial puncture without instillation + 6 months colchicine; NEPIN (neoplastic effusion and pericardial instillation)--pericardiocentesis and drainage + intrapericardial instillation of cisplatin or thiotepa.
