title: Frequency of recurrence of pericardial tamponade in patients with extended versus nonextended pericardial catheter drainage.
abstract: Recurrence of pericardial tamponade is relatively common after pericardiocentesis. We evaluated the clinical and procedural predictors of recurrent pericardial tamponade after pericardiocentesis. We included 157 consecutive patients with pericardial tamponade (age 62 ± 18 years, 54% men) who had undergone pericardiocentesis from 2000 to 2007. An intrapericardial catheter was used for prolonged drainage of the pericardial effusion (78% of cases) at the discretion of the operator. The overall recurrence rate 11.8 ± 0.6 months after pericardiocentesis was 20% and the mean interval to recurrence was 1.2 ± 2.1 months. However, patients with extended catheter drainage had a reduced recurrence rate of 12% compared to 52% in patients without extended drainage (p <0.001). In the Cox regression modeling, absence of extended drainage (hazard ratio [HR] 4.1, 95% confidence interval [CI] 1.7 to 10, p = 0.002), incomplete drainage of pericardial effusion (HR 9.7, 95% CI 3.6 to 22.7, p <0.001), loculated effusion (HR 11.1, 95% CI 2.9 to 43, p = 0.001), and malignancy (HR 3.3, 95% CI 1.8 to 10.3, p = 0.037) independently correlated with recurrence at 1 year. In conclusion, extended pericardial drainage after catheter placement is associated with a reduced recurrence of pericardial tamponade after pericardiocentesis.
