二尖瓣-主动脉瓣间纤维假性动脉瘤是罕见的,特别是在儿童中,而且可能是致命的.本文介绍了两例小儿二尖瓣-主动脉瓣膜间纤维假性动脉瘤:一例继发于感染性心内膜炎,另一例被证实为先天性。本研究显示的二尖瓣-主动脉瓣间纤维假性动脉瘤的特征性超声心动图表现将提高诊断效能并指导早期临床干预。
Pseudoaneurysm of the mitral-aortic intervalvular fibrosa is rare, particularly in children, and is potentially fatal. This article presents two cases of pediatric mitral-aortic intervalvular fibrosa pseudoaneurysm: one secondary to infective endocarditis and the other confirmed to be congenital in nature. The characteristic echocardiographic manifestations of mitral-aortic intervalvular fibrosa pseudoaneurysm demonstrated in this study will enhance diagnostic efficacy and guide early clinical intervention.
