The mitro-aortic intervalvular fibrosa (MAIVF) connects the anterior mitral leaflet to the posterior portion of the aortic annulus. The pseudoaneurysm of MAIVF is one of the uncommon but catastrophic complications of native or prosthetic aortic valve endocarditis or chest trauma. We report a case of infective endocarditis of mitral valve complicated by development of pseudoaneurysm of MAIVF, and fistulous formation causing massive shunt flow from the ascending aorta above the non-coronary cusp to the left ventricle outflow tract.
二尖瓣-主动脉瓣间纤维组织(MAIVF)连接二尖瓣前叶与主动脉瓣环后部。MAIVF假性动脉瘤是天然或人工主动脉瓣心内膜炎或胸部创伤少见但灾难性的并发症之一。我们报告1例二尖瓣感染性心内膜炎合并MAIVF假性动脉瘤形成及瘘管形成,导致大量分流从非冠状动脉瓣上方的升主动脉流向左心室流出道。
