Background: Pericardiocentesis is an emergent and high-risk procedure that has become progressively more rare in the Emergency Department with availability of cardiac catheterization labs. Also, ultrasound has revolutionized the safety of pericardiocentesis and the procedure continues to be a critical skill for emergency physicians that requires practice to achieve competency. Simulation provides an opportunity to allow learners to practice this skill on task trainers, thereby reducing risk to patients.Objective: Commercially available pericardiocentesis task trainers are expensive. Previously described do-it-yourself pericardiocentesis task trainers have suffered from poor quality ultrasound images. Our objective was to construct a pericardiocentesis task trainer, using a porcine heart, that allowed simulating pericardiocentesis from all conventional echocardiographic views and provided high-fidelity images. We assessed our model’s effectiveness in improving the comfort of early learners in this life-saving skill.
