Mitral valve regurgitation followed by blunt chest trauma in a paediatric patient: a case report.

We report a paediatric case where severe mitral valve regurgitation occurred led by blunt chest trauma. Medical treatment was undertaken, and surgical mitral valve repair was postponed until half a year after the initial injury, followed by an uneventful postoperative recovery. We highlight the importance of echocardiographic evaluation for traumatic valve insufficiency. The medical strategy and timing of surgical intervention should be individualised.
