Intrapericardial treatment of autoreactive myocarditis with triamcinolon - Successful administration in patients with minimal pericardial effusion
MetadataShow full item record
A major clinical drawback in the treatment of autoreactive pericarditis is its inherent feature to relapse. Intrapericardial treatment with triamcinolone was reported to be efficient in patients with large, symptomatic autoreactive pericardial effusions, avoiding side effects of systemic treatment as well as compliance problems. Intrapericardial treatment with 300 mg/m(2) triamcinolone was for the first time performed in patients with autoreactive myopericarditis and minimal pericardial effusions (75 to 110 mi). After 12 months of follow-up both patients are asymptomatic and there were no further recurrences of pericardial effusion. Pericardiocentesis in these patients was performed with the application of the PerDUCER(R) device, guided by pericardioscopy. This device has a hemispherical cavity at the top of the instrument connected with a vacuum-producing syringe. In this cavity the pericardium is captured by vacuum and tangentially punctured by the introducer needle. Pericardium that... can be captured, must be up to 2 mm thin to fit into the hemispherical cavity. Pericardioscopy performed from the anterior mediastinum significantly contributed to the success of the procedures enabling visualization of the portions of the pericardium free of adipose tissue or adhesions, suitable for puncture with the PerDUCER(R). In conclusion, intrapericardial treatment of symptomatic autoreactive myopericarditis with minimal pericardial effusion was safely and efficiently performed in 2 patients. Pericardiocentesis was enabled by means of the PerDUCER(R) device, facilitated by pericardioscopy.
