[Traumatic aortic regurgitation: diagnostic, management and treatment]

Abstract

Traumatic aortic valve regurgitation is a rare complication of non-penetrating thoracic trauma. The most frequent lesion is the isolated injury of the non-coronary cusp. Actually, the transoesophageal echocardiography is the procedure of choice to confirm the diagnosis and to reveal the associated cardiovascular lesions. Surgical management with early operation is the best policy, however this surgery can be delayed for treatment of other life-threatening injuries. Up today, aortic valve replacement (AVR) was recommended to repair traumatic aortic valve regurgitation; nevertheless, in the recent international literature, the number of cases reports with conservative surgery (CS) is increasing: 10 AVR (group I) and 10 CS (group II). Analysis of the post-operative and long term periods shows good results: it confirms the excellent clinical evolution in the group I (mean time of follow-up: 18.2 +/- 16.3 months), and reveals satisfactory results in the group II for patients with isolated lesion (mean time of follow-up: 29.1 +/- 30.7 months). In conclusion, each time the traumatic aortic regurgitation is due to an isolated lesion, the conservative surgery should be performed in order to avoid aortic valve replacement and its potential complications especially in young patients with healthy valves. However, the aortic valve replacement is the safest technique for complex or multiple injuries of the aortic valve.
