Summary
Blunt chest trauma can cause rare tricuspid valve regurgitation, often diagnosed years later. Successful surgical repair using native valve salvage techniques restored normal function in two patients.
Area of Science:
- Cardiology
- Cardiac Surgery
- Trauma Medicine
Background:
- Blunt chest trauma is a significant cause of cardiac injury.
- Tricuspid valve regurgitation can occur secondary to chest trauma, though uncommon.
- Delayed diagnosis of traumatic tricuspid valve regurgitation is possible.
Observation:
- Two patients presented with tricuspid valve regurgitation years after blunt chest trauma.
- The regurgitation stemmed from anterior leaflet prolapse due to chordal and papillary muscle rupture with annular dilatation.
- Diagnosis was delayed, occurring 13 and 6 years post-trauma.
Findings:
- Successful management was achieved through native valve salvage.
- Surgical repair involved artificial chordae implantation, papillary muscle reinsertion, and ring annuloplasty.
- Both patients experienced complete recovery of heart function.
Implications:
- Highlights the importance of considering tricuspid valve injury in patients with a history of blunt chest trauma.
- Emphasizes the efficacy of valve-sparing surgical techniques for traumatic tricuspid regurgitation.
- Suggests the need for increased clinical awareness and diagnostic vigilance for this rare condition.
