[Evaluation of echo-guided pericardiocentesis in cardiac tamponade].

Between April 1982 and December 1995, 78 consecutive patients with an average age of 57 +/- 13 years underwent echo-guided pericardiocentesis in the intensive care unit for poorly tolerated pericardial effusions. The patients were admitted to the cardiology departments of Ambroise-Paré Hospital at Boulogne (n = 44). Gilles-de-Corbeil Hospital at Corbeil-Essonnes (n = 31) and Val-de-Grâce Hospital in Paris (n = 3). The underlying aetiologies were malignant disease (n = 31), idiopathic (n = 13), post-surgery (n = 7), infection (n = 7), autoimmune (n = 6), post-radiotherapy (n = 6), post-myocardial infarction (n = 3), chronic renal failure (n = 3) and coagulation defects (n = 2). Pericardial puncture was undertaken by the subxiphoid (n = 77) or left parasternal (n = 1) approaches under guidance of echocardiography. Intra-pericardial contrast was used to verify the position of the catheter. The average volume of liquid drained was 580 +/- 390 mL. After pericardiocentesis, continuous drainage was continued in 17 patients for an average duration of 63 +/- 29 hours. The total average volume was 750 +/- 330 mL. The major complications were a) three deaths during the puncture, not caused by the procedure after post-mortem study, b) ten right ventricular punctures with no consequences in 9 cases, c) two cases of shock, one of which was due to a pre-existing septicaemia of pulmonary origin, d) two non-sustained ventricular arrhythmias. The minor incidents were six vasovagal syndromes during the procedure and four paroxysmal supraventricular arrhythmias. Emergency surgical drainage was required (n = 3) for a failed procedure and late surgical drainage (n = 12) for persistence or recurrence of the effusion. No surgical drainage was required in the 17 patients placed under continuous aspiration. Echo-guided pericardiocentesis is a simple procedure and provides rapid haemodynamic relief in subjects generally in serious condition. Continuous aspiration may help avoid the need for surgical drainage for persistence or recurrence of the effusion.
