Right ventricular free wall perforation during pericardiocentesis, and an inappropriate device selection for percutaneous treatment.

Right ventricular (RV) perforation is a rare but life-threatening complication of pericardiocentesis and is usually treated surgically. We presented a case of RV free wall perforation, which occurred during pericardiocentesis and tried to be closed percutaneously with the Amplatzer vascular plug-III (AVP-III) device. The occluder device sealed the perforation, but it was in an insecure position; therefore, the patient underwent surgical repair. As an AVP-III device, with a middle disk thicker than the RV myocardium, it may cause the RV myocardium to stretch outwards, so it should not be used for the treatment of RV perforation by the transcatheter way.
