Pericardiocentesis: differential aspects of a common procedure.

ABSTRACT

OBJECTIVE: To evaluate the risk and effectiveness of pericardiocentesis in primary and repeat cardiac tamponade. DESIGN: Retrospective analysis. SETTING: Intensive care unit in a medical university hospital. PATIENTS Sixty-three consecutively admitted patients with cardiac tamponade. INTERVENTIONS: In all patients pericardiocentesis was performed via the subxiphoid pathway after echocardiographic detection of the pericardial effusion. MEASUREMENTS AND RESULTS: There was no adverse event in patients undergoing primary pericardiocentesis, which was sufficient to resolve pericardial effusion in 51 of 63 patients (81%). However, repeat pericardiocentesis necessitated by the recurrence of symptomatic pericardial effusion yielded suboptimal results in 10 of 12 patients (83%). CONCLUSION: Pericardiocentesis is the treatment of choice for primary symptomatic pericardial effusion. In recurrent pericardial effusion surgical approaches appear to be preferable.
