Delayed Traumatic Tricuspid Valve Regurgitation Caused by Blunt Chest Trauma: A Case Report and Literature Review

Traumatic tricuspid regurgitation (TTR) is an uncommon cause of acute right ventricular dysfunction. The surgical approach can be complex, and repair tends to have a lower success rate when right heart failure symptoms are present. We present a case of a 56-year-old man with chronic isolated tricuspid valve flail and severe TTR due to high-energy blunt chest trauma from a vehicle accident 24 years prior. This report emphasizes the critical role of echocardiography in diagnosing trauma-related primary tricuspid regurgitation and the necessity of early detection to facilitate surgical intervention before irreversible damage happens.
