Delayed Diagnosis of Severe Traumatic Tricuspid Regurgitation After Traffic Injury

Traumatic accidents sometimes cause primary traumatic tricuspid regurgitation (TR), and the diagnosis is occasionally delayed due to the load adaptability of the right ventricle, which may lead to fatal outcomes. Here, we report a case of a 28-year-old man with traumatic TR, which presented with late-onset exertional dyspnea 5 years after a blunt chest injury from a bicycle accident. The chordae tendineae of anterior tricuspid leaflet was ruptured with right heart dilatation, and he underwent surgical tricuspid valvuloplasty. For the patients having a chest traumatic accident, echocardiographic screening is recommended considering TR occurrence. < The early detection with echocardiographic screening after chest traumatic accident followed by immediate surgical intervention is crucial to improve the prognosis of traumatic tricuspid regurgitation.>.
