Severe tricuspid regurgitation (TR) after blunt chest trauma is rare and often results from damage to the subvalvular apparatus. When injured, the damaged subvalvular apparatus may break immediately or at a later stage due to mechanical fatigue. We report the case of a 30-year-old man who sustained a blunt thoraco-abdominal trauma in a motorbike accident. The patient's condition immediately after the accident precluded any intervention for the moderate TR that was detected by transesophageal echocardiography. However, he later developed a severe TR which required surgical intervention 11 months after the accident. The operative findings included a ruptured anterior common chordae, a contracted and perforated anterior leaflet, and an enlarged annulus. A satisfactory valve competence was achieved with several techniques including chordae re-implantation, suture commissurotomy, and ring annuloplasty. This report highlights the unpredictable course of deterioration in traumatic TR and the possibility of complex repair.
Key Words:
