一名 26 岁的日本女性因之前不明原因的高烧而出现新发主动脉瓣反流。发烧期间，尽管频繁进行血培养，但菌血症或真菌血症并不明显，但静脉注射帕尼培南/倍他米隆（PAPM/BP）逐渐使发烧下降。超声心动图和手术过程显示四尖瓣主动脉瓣（QAV），由两个相等的较大尖瓣和两个不相等的较小尖瓣组成（f 型）。一个较小的附属尖头被损坏，但没有显示出活跃的植被。使用冠状动脉下技术植入美敦力 Freestyle 生物假体。尽管这种罕见的瓣膜异常导致心内膜炎的风险尚未得到充分记录，但目前的病例可能支持传统的假设，即具有不等小瓣膜的患者容易患心内膜炎。
A 26-year old Japanese woman experienced new aortic valve regurgitation associated with a preceding high fever of unknown cause. During the fever episode, although bacteremia or fungemia was not evident despite frequent blood cultures, intravenous panipenem/betamipron (PAPM/BP) gradually resulted in decline of the fever. Echocardiography and operative procedures revealed a quadricuspid aortic valve (QAV), which was composed of two equal larger cusps and two unequal smaller cusps (type f). A smaller accessory cusp was damaged but showed no active vegetation. A Medtronic Freestyle bio-prosthesis was implanted using a subcoronary technique. Although the risk of endocarditis for this rare valve abnormality is not well documented, the present case may support the conventional assumption that patients with unequal small cusps are prone to endocarditis.
