Acute Marginal Artery Laceration as a Complication of Pericardiocentesis.

The safety of pericardiocentesis as a therapy for cardiac tamponade has improved since the advent of echocardiography-guided pericardiocentesis. The most life-threatening, albeit rare, complication is injury to the coronary vessels or ventricular wall resulting in recurrent tamponade. We present a rare case of acute marginal artery laceration resulting from pericardiocentesis. (Level of Difficulty: Beginner.).
