摘　　要：目的观察二尖瓣主动脉瓣瓣间纤维假性动脉瘤(P-MAIVF)超声心动图特点。方法结合相关文献,回顾分析6例P-MAIVF的临床特征及超声心动图表现。结果 6例P-MAIVF均位于主动脉瓣根部后方,收缩期膨胀而舒张期塌陷是其特征性表现。6例中,5例合并感染性心内膜炎,1例为心房颤动射频消融并发症,4例合并主动脉瓣二叶畸形,2例假性动脉瘤破入升主动脉。结论经胸超声心动图是诊断P-MAIVF的首选方法;彩色血流多普勒有助于观察是否有破口形成,三维超声有助于观察病灶与邻近结构的空间位置关系。Objective To explore the clinical and echocardiographic features of pseudoaneurysm of mitral-aortic intervalvular fibrosa （P-MAIVF）. Methods Clinical characteristics and transthoracic echocardiographic features of 6 patients with P-MAIVF were retrospectively analyzed compared with relevant literature. Results P-MAIVF located in the posterior aspect of aortic root, which expanded during systole and collapsed during diastole period. Among 6 cases, 5 associated with endocarditis, 1 P-MAIVF occurred secondary to transcatheter radio frequency ablation for treatment of atrial fibrillation, 4 associated with aortic bicuspid, while 2 P-MAIVF ruptured into the ascending aorta. Conclusion Transthoracic echocardiography may be the best tool in diagnosis of P-MAIVF. CDFI can be used to identify the ostium of rupture. Real time three-dimensional transthoracic echocardiography is helpful to determining the relationship of P-MAIVF and adjacent anatomic structures.
