Echocardiography-guided pericardiocentesis with probe-mounted needle: Report of 53 cases☆

Abstract 

Fifty-three pericardiocentesis procedures were performed on 48 patients from 1993 to 2000 at our coronary care unit. Percutaneous puncture (anterior thoracic in 43 cases, subxiphoid in 10 cases) was performed at the site closest to the exploring probe, where the largest amount of fluid was detected. A needle carrier supported by a bracket with two fixed angulations was mounted on the probe. The needle was advanced through the tissues and inside the pericardial space under continuous visualization. The procedure was successful in 52 of 53 cases. In 1 case of diagnostic pericardiocentesis, the pericardial space was impossible to reach because of the minimal amount of pericardial fluid. In 1 case of acute tamponade after transcatheter ablation of the atrioventricular node, the pericardial puncture caused a pleural-pericardial shunt with consequent drainage of pericardial fluid into the pleural space and symptom resolution. In 1 case, a transient atrioventricular type III block occurred. Emergency surgical drainage was not required in any of the cases. No puncture of cardiac walls ever occurred in this series of patients. No major complications occurred; the incidence of minor sequelae was lower than the incidence reported by other studies on pericardiocentesis without continuous visualization. Our technique appears to be safe and easy to perform even in the presence of minimal amounts of pericardial fluid. (J Am Soc Echocardiogr 2001;14:821-4.)
