Malignant Pericardial Effusion
ABSTRACT Malignant pericardial effusion is a common and serious manifestation in malignancies. The origins of the malignant process include solid tumors or hematological malignancies, while primary neoplasms of the pericardium are less common. In the oncological patient, pericardial effusion may develop by several different mechanisms, namely by direct or metastatic spread of the primary process or as a complication of antineoplastic therapies. In some cases, pericardial effusion may be the first manifestation of the disease, and that is why malignancy must be excluded in every case of an acute pericardial disease with cardiac tamponade at presentation, rapidly increasing pericardial effusion and an incessant or recurrent course. Thus, the definite differentiation of malignant pericardial effusion and rapid diagnosis are of particular therapeutic and prognostic importance. Management of these patients is multidisciplinary and requires team work, but at present there is a need for further research. An individual treatment plan should be established, taking into account cancer stage, the patient's prognosis, local availability and experience. In emergency cases with cardiac tamponade or significant effusion, initial relief can be obtained with pericardiocentesis. Despite the magnitude of this serious problem, little progress has been made in the treatment of pericardial effusion secondary to malignant disease.

ABSTRACT: Objectives: Echocardiography-guided pericardiocentesis has been the leading procedure for diagnosis and therapy of pericardial effusion. We aimed to identify risk factors for recurrence, complications, and mortality in pericardial effusion patients treated with pericardiocentesis. Methods: We identified and collected data from 8,101 patients receiving pericardiocentesis between 1997 and 2010 from the Taiwan National Health Insurance Research Database. A multivariate regression model was used to investigate risk factors for recurrence, complications, and death. Results: There were 8,565 admissions among 8,101 patients. The most common underlying condition was malignancy (41%), especially lung cancer (23%), tuberculosis (9.0%), and acute pericarditis (8.2%). Surgical drainage was required in 12.7% of cases. Recurrence was more likely in patients with malignancy (HR 2.20, p < 0.001), but complications were less likely (OR 0.52, p = 0.003). In-hospital death numbers and complication risks (OR 2.38, p < 0.001; OR 1.27, p = 0.01) were greater in the catheter-related cardiac procedure group than in the other groups. Conclusions: Malignant neoplasms and catheter-based cardiac procedures have become major risk factors for adverse events in patients receiving pericardiocentesis in Taiwan. Malignancy leads to an increase in recurrence and in-hospital mortality but is associated with a lower rate of acute complications. Cardiac catheterization procedures and surgery increase both complications and in-hospital mortality. © 2014 S. Karger AG, Basel.Cardiology 12/2014; 130(1):37-45.
