The traumatic aortic valvular insufficiency (TAVI), through less frequent after a non-penetrating thoracic traumatism, is a serious entity with a very reserved prognosis. So it must be suspected in every patients with signs or symptoms of de novo heart failure post-traumatism. The transthoracic echocardiography and eventually transesophageal echocardiography have a fundamental role in the confirmation of the diagnosis. The clinical picture of traumatic aortic regurgitation is quickly evolutionary and the non efficacy of medical therapy has placed the valvular substitution surgery as the best succeeded treatment. With the advent of the aortic valve repairing surgery some TAVI cases has been submitted to this procedure. Nevertheless, the development of residual aortic regurgitation in these situations, usually requiring later valvular replacement surgery, make the aortic valvuloplasty a controversial surgical technique. The AA describe a recent clinical case of aortic regurgitation after a non-penetrant thoracic traumatism, discussing the aspects connected with physiopathology, diagnosis and therapy. The singularity of this case was based on the fact that the initial clinical diagnosis had been prejudiced by the context of a polytraumatism and there had been a time free of symptoms between the traumatism and the beginning of the symptomatology of left ventricular failure. Even though the identification of the problem allowed an intensive treatment of this serious situation that ended with the replacement of the aortic valve by mechanical aortic prosthesis, with the patient's total recovery.
创伤性主动脉瓣关闭不全(TAVI)在非穿透性胸部创伤后虽不常见,但却是一种预后极差的严重病症。因此,对于每一位创伤后出现新发心力衰竭体征或症状的患者都应怀疑此病。经胸超声心动图以及必要时的经食管超声心动图在确诊中起着至关重要的作用。创伤性主动脉反流的临床表现进展迅速,药物治疗无效使得瓣膜置换手术成为最成功的治疗方法。随着主动脉瓣修复手术的出现,一些TAVI病例已接受该手术。然而,在这些情况下残余主动脉反流的发生,通常需要后期进行瓣膜置换手术,这使得主动脉瓣成形术成为一种有争议的外科技术。本文作者描述了一例非穿透性胸部创伤后主动脉反流的近期临床病例,讨论了与病理生理学、诊断和治疗相关的方面。该病例的独特之处在于,最初的临床诊断受到多发伤背景的影响,并且在创伤与左心室衰竭症状出现之间存在一段无症状期。尽管问题的识别使得对这种严重情况进行了强化治疗,最终通过机械主动脉假体置换主动脉瓣,患者完全康复。
