Abstract:
Severe mitral regurgitation developed in a patient after a lateral-impact motor vehicle accident. The papillary muscle head was disrupted without evidence of other myocardial injury. We hypothesize that a dramatic and sudden increase in intrathoracic pressure may have produced the injury. The patient experienced progressive heart failure and underwent successful mitral valve repair 9 days after the accident.
Insights
A motor vehicle accident caused severe mitral regurgitation due to papillary muscle disruption. This led to heart failure, requiring successful mitral valve repair.
Area of Science:
- Cardiology
- Trauma Surgery
- Cardiovascular Surgery
Background:
- Motor vehicle accidents can cause significant blunt chest trauma.
- Mitral regurgitation is a serious cardiac complication that can arise from chest trauma.
- Papillary muscle rupture is a rare but devastating consequence of cardiac injury.
