Surgical repair for primary tricuspid regurgitation related to trauma

We report a case of a 45-year-old man presenting with tachycardia and palpitation. Echocardiography indicated severe tricuspid regurgitation. We suspected traumatic tricuspid damage due to high energy trauma in a motor vehicle accident 17 years earlier. He underwent a sternotomy, and his tricuspid valve was repaired with chordal reconstruction, indentation closure, and ring annuloplasty. The postoperative period was uneventful, and he was discharged 10 days after the operation. This report highlights the value of echocardiography for diagnosis of primary tricuspid regurgitation related to trauma, and the importance of early diagnosis to allow surgical intervention before irreversible damage occurs.Learning objectiveTraumatic tricuspid regurgitation is a rare cardiovascular complication of blunt chest trauma. The mechanism of the tricuspid valve injury is thought to be secondary to sudden impact causing an anteroposterior compression of the right ventricle by the sternum in end-diastole. This injury is often incidentally identified or can be missed until the patient experiences symptoms of right heart failure resulting from severe tricuspid regurgitation.
