Dynamic monitoring of cardiac foreign body by perioperative echocardiography: A case study.

Cardiac foreign bodies, especially those with sharp tips, may lead to unpredictable complications, such as penetrating cardiac injuries. Yet there have not been many reports of penetrating cardiac injuries caused by a needle that migrates from the neck to the heart. We herein present a review of such a case, focusing on the dynamic monitoring by perioperative echocardiography. The needle was represented on the monitor as a linear artifact that had penetrated through the ventricular wall and caused increasing pericardial effusion. Fortunately, the needle was successfully removed before it completely entered the right ventricular cavity. In this case, perioperative echocardiography played a significant role in clinical emergency decision making.
