Abstract: Traumatic tricuspid regurgitation is a rare complication after blunt chest trauma and frequently misdiagnosed during the initial assessment. Traumatic tricuspid valve injury associated with right-to-left shunting via a patent foramen ovale causing hypoxemia and desaturation is noted even less frequently. Here we report a case of a patient with right heart failure symptoms and desaturation due to right-to-left shunting via a patent foramen ovale secondary to traumatic tricuspid insufficiency detected 20 years after a car accident. Surgery was required, consisting of tricuspid valve replacement. This case reminds that physicians in the emergency department should be aware of this potential complication following nonpenetrating chest trauma and its different clinical presentation. Patients with suspected valve lesion should undergo close echocardiographic follow-up to permit early detection of valve injury and timely surgical treatment.
