An Asymptomatic Needle in the Left Ventricular Anterolateral Wall: A Prison Inmate's Strange Radio Antenna

A foreign body such as a needle in the heart can be life‐threatening. While this may occur accidentally, needles may be inserted into the body by psychiatric patients or in cases involving domestic violence. A needle can migrate through the thorax toward the heart. In drug users, needles may also reach the right ventricle via the peripheral veins. Cardiac injury can occur via the esophagus after swallowing a needle. The clinical outcome may vary from an asymptomatic situation to tamponade or shock, depending on how severely the cardiac structures are affected. In injuries involving the thorax, pneumothorax may cause sudden shortness of breath. Here, we report the case of a 34‐year‐old male prison inmate who accidentally lodged a pin in his left ventricle while asleep. As he has refused surgery, it was decided to follow the patient carefully.
