Abstract:
Non-penetrating cardiac trauma resulting in mitral valve rupture is uncommon, requiring a high degree of suspicion for diagnosis. Sudden and severe mitral regurgitation, unless surgically corrected rapidly lead to congestive heart failure and death. We report a patient with traumatic rupture of the antero-lateral papillary muscle of the mitral valve and pericardial injury, after a lateral blunt chest trauma, who successfully underwent emergency mitral valve replacement.
Insights
Non-penetrating chest trauma can cause rare mitral valve rupture. Prompt surgical repair is crucial to prevent fatal heart failure.
Area of Science:
- Cardiology
- Trauma Surgery
Background:
- Non-penetrating cardiac trauma is an infrequent cause of mitral valve rupture.
- Early diagnosis of mitral valve rupture requires a high index of suspicion.
Observation:
- A patient sustained a lateral blunt chest trauma, resulting in pericardial injury and traumatic rupture of the mitral valve's antero-lateral papillary muscle.
Findings:
- The patient presented with sudden and severe mitral regurgitation.
- Successful emergency mitral valve replacement was performed.
Implications:
- This case highlights the importance of considering mitral valve injury in blunt chest trauma.
- Rapid surgical intervention is vital for survival in cases of traumatic mitral regurgitation.

Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
