Abstract：
Antibiotic prophylaxis prior to dental work in bicuspid aortic valve (BAV) patients is currently a matter of debate. The American Dental Association does not require those with native BAV to receive antibiotic prophylaxis prior to dental work as BAV is considered an \"intermediate\" risk for infective endocarditis (IE). We present the case of a 63-year-old male, with a medical history of BAV, who acquired Streptococcus sanguinis IE after a routine dental cleaning four months prior to initial onset of symptoms. He exhibited new-onset and severe aortic regurgitation at presentation, requiring urgent aortic valve replacement to restore valve function. BAV patients are at high risk of IE, emphasizing the need for prophylactic antibiotics in dental cleaning as well as invasive dental procedures in those with BAV.
摘要：
在二叶主动脉瓣（BAV）患者的牙科工作之前进行抗生素预防目前是一个有争议的问题。由于BAV被认为是感染性心内膜炎（IE）的“中等”风险，因此美国牙科协会不要求那些患有天然BAV的患者在牙科工作之前接受抗生素预防。我们介绍一个63岁的男性，有BAV病史,在最初出现症状前四个月进行常规牙齿清洁后获得血链球菌IE。他在就诊时表现出新发和严重的主动脉瓣反流，需要紧急主动脉瓣置换术以恢复瓣膜功能。BAV患者患IE的风险很高，强调在牙齿清洁中需要预防性抗生素，以及患有BAV的患者的侵入性牙科程序。
