Needle fragment embolism into the right ventricle: a rare cause of chest pain case report and literature review.

Chest pain in young adults is usually self-limited and of benign etiology. However, rare causes of chest pain must be considered in patients for whom initial diagnostic tests are negative, particularly if unusual risk factors are identified. The authors present a rare case describing a 27-year-old male intravenous drug user who developed transient chest pain most likely secondary to pericardial irritation caused by a needle fragment that embolized from a peripheral vein to his right ventricle. The current literature on intracardiac needles and similar foreign bodies is discussed, providing insight to the epidemiology, complications, and treatment of such patients.
