Aortic valve endocarditis can cause complications due to involvement of the subaortic structures. These complications include satellite vegetations on the aortic regurgitant jet lesion sites, involvement of the anterior or posterior mitral valve leaflets in the form of aneurysms, perforation, and involvement of the mitral-aortic intervalvular fibrosa, namely abscess, aneurysm, and perforation into the left atrium or the pericardial sac. These complications can be identified accurately by echocardiography. We report an unusual case which demonstrates (1) coexistence of both mitral-aortic intervalvular fibrosa and mitral valve aneurysms, and (2) echocardiographic follow-up of a mitral valve aneurysm to perforation. These complications were recognized by transesophageal echocardiography and verified at surgery.
主动脉瓣心内膜炎可因主动脉下结构受累而导致并发症。这些并发症包括主动脉反流喷射病变部位的卫星赘生物、二尖瓣前叶或后叶以动脉瘤、穿孔形式受累，以及二尖瓣-主动脉瓣间纤维组织受累，即脓肿、动脉瘤以及穿破至左心房或心包腔。这些并发症可通过超声心动图准确识别。我们报告一例罕见病例，该病例显示：（1）二尖瓣-主动脉瓣间纤维组织与二尖瓣动脉瘤并存；（2）二尖瓣动脉瘤穿孔的超声心动图随访情况。这些并发症通过经食管超声心动图得以识别，并在手术中得到证实。
