Given over 2.64 million total percutaneous coronary interventions performed in the United States, and that acute cardiac tamponade is one of the most common complications of such percutaneous coronary interventions, clinicians should be familiar with diagnosing impending pericardial tamponade, and a simple and safe bedside technique for drainage. We describe a technique for echocardiographically guided rescue pericardiocentesis in the setting of acute tamponade to demonstrate the efficacy and safety of this technique for pericardial drainage with reduced complication risk as compared to a landmark-based approach. A case of a 52-year-old male was brought to the Emergency Department after a witnessed cardiac arrest. He underwent cardiac catheterization and percutaneous coronary stent implantation. Thirty minutes after stenting, the patient developed signs of cardiac tamponade, and point-of-care echocardiogram confirmed a pericardial effusion. An in-plane ultrasound-guided pericardiocentesis was successfully performed by the junior house-staff under direct attending supervision. Serial echocardiograms demonstrated preserved left ventricular systolic function without new effusion. The patient remained hemodynamically stable for 48 hrs following the procedure at which time the pericardial catheter was removed. Ultrasound image guided pericardiocentesis is a rapid and safe technique for pericardial drainage with reduced complication risk as compared to a landmark-based approach.
