BackgroundOptimal management of cardiac tamponade resulting from pericardial effusion remains controversial.MethodsCardiac tamponade in 117 patients was treated with either subxiphoid pericardiostomy (n = 94) or percutaneous catheter drainage (n = 23). Percutaneous catheter drainage was used for patients with hemodynamic instability that precluded subxiphoid pericardiostomy. Effusions were malignant in 75 (64%) of 117 patients and benign in 42 (36%) of 117.ResultsSubxiphoid pericardiostomy had no operative deaths and a complication rate of 1.1% (1 of 94). In contrast, percutaneous drainage had significantly (p < 0.05) higher mortality and complication rates of 4% (1 of 23) and 17% (4 of 23), respectively. Patients with an underlying malignancy had a median survival of 2.2 months, with a 1-year actuarial survival rate of 13.8%. In comparison, patients with benign disease had a median survival of 42.8 months and a 1-, 2-, and 4-year actuarial survival rate of 79%, 73%, and 49%, respectively (p < 0.05). Effusions recurred in 1 (1.1%) of 94 patients after subxiphoid pericardiostomy compared with 7 (30.4%) of 23 patients with percutaneous drainage (p < 0.0001).ConclusionsBenign and malignant pericardial tamponade can be safely and effectively managed with subxiphoid pericardiostomy. Percutaneous catheter drainage should be reserved for patients with hemodynamic instability.
