Summary
Severe mitral regurgitation from blunt chest trauma is rare. This case details successful mitral valve repair via papillary muscle reimplantation and annuloplasty 5 years after initial injury.
Area of Science:
- Cardiology
- Cardiac Surgery
- Trauma Surgery
Background:
- Mitral valve injury following blunt chest trauma is an uncommon occurrence.
- Severe mitral regurgitation can result from such injuries, necessitating surgical intervention.
- Delayed presentation of symptoms is possible, as seen in this case.
Observation:
- A 22-year-old male presented with severe mitral regurgitation.
- Echocardiography revealed a partial tear of the anterolateral papillary muscle and prolapse of the mitral valve.
- The injury was attributed to blunt chest trauma sustained 5 years prior.
Findings:
- Surgical repair involved reimplantation of the papillary muscle to the left ventricular wall.
- Ring annuloplasty was performed concurrently.
- The procedure successfully corrected the severe mitral regurgitation without residual leakage.
Implications:
- This case demonstrates the feasibility of late mitral valve repair after blunt chest trauma.
- Papillary muscle reimplantation and annuloplasty are effective surgical techniques for traumatic mitral regurgitation.
- Early recognition and management of traumatic cardiac injuries are crucial for favorable outcomes.
