BACKGROUND
Windsock deformities, though rare, represent a severe form of valvular aneurysm distinguished by localized balloon-like protrusions of the leaflet body. Here, we present a compelling case of windsock mitral valve (MV) formation subsequent to incompletely managed aortic valve (AV) endocarditis. The case is illustrated through radiographic, intraoperative, and histopathologic images.
CASE PRESENTATION
We present the case of a 44 year old male patient who presented with symptoms suggestive of infective endocarditis. Despite initiation of appropriate antimicrobial therapy and surgical intervention for AV involvement, the patient developed progressive valvular dysfunction. Subsequent imaging studies revealed the emergence of windsock deformity in the mitral valve apparatus. Intraoperative assessment confirmed the presence of this rare valvular anomaly, which was further corroborated by histopathologic examination.
CONCLUSIONS
We provide, for the first time in the literature, a clear intraoperative view and example of windsock mitral valve (MV) developing after incompletely treated aortic valve (AV) endocarditis.
背景
风袋样畸形虽然罕见，但代表了一种严重的瓣膜瘤形式，其特征为瓣叶体局部呈气球样突出。在此，我们展示了一例主动脉瓣心内膜炎治疗不彻底后形成风袋样二尖瓣的令人信服的病例。通过影像学、术中及组织病理学图像对该病例进行说明。
病例介绍
我们报告一例44岁男性患者，其出现提示感染性心内膜炎的症状。尽管针对主动脉瓣受累启动了适当的抗菌治疗和手术干预，但患者仍出现进行性瓣膜功能障碍。随后的影像学检查显示二尖瓣装置出现风袋样畸形。术中评估证实存在这种罕见的瓣膜异常，组织病理学检查进一步证实了这一点。
结论
我们在文献中首次提供了主动脉瓣心内膜炎治疗不彻底后形成风袋样二尖瓣的清晰术中视野及实例。
