Blunt chest trauma is the major cause of traumatic tricuspid valve regurgitation (TTVR), a secondary type of tricuspid regurgitation. It is a rare condition; however, it may lead to severe consequences if not treated in a timely manner. TTVR should be considered in a patient presenting with chest trauma. In this case, we report a case of a young male who presented after a motor vehicle accident with secondary tricuspid valve regurgitation due to blunt chest trauma as well as a patent foramen ovale.
