Foreign bodies in the heart are rare occurrences with a limited evidence base to guide recommendations on management. We report a case of multiple cardioembolic strokes as a result of a self-inflicted sewing needle puncture from the anterior chest through the right ventricle and interventricular septum with its tip in the left ventricle close to the subvalvular apparatus in a 39-year-old psychiatric patient. We discuss issues surrounding decision making and ongoing care and highlight the importance of further follow-up and reporting of cases to form a robust evidence base to guide future recommendations.
