Abstract
The report presented a 20-year-old male case with multiple stab wounds on the right lateral chest wall, and a latent heart injury was found during the right lateral thoracotomy. A laceration on the right ventricle was verified by a median sternoctomy and repaired using an Inforce suture. The clinicians should not neglect the lower probability of life-threatening thoracic injuries following stab wounds to the chest, despite the initial location of anatomy.
