Abstract：Objective: The destruction of mitral-aortic intervalvular fibrosa(MAIVF) complicated by infective endocarditis is rare, we concluded and analyzed the echocardiographic features and clinical characteristics of these patients retrospectively. Methods: We analyzed echocardiographic materials of 18 cases which were diagnosed by echocardiography of the destruction of MAIVF retrospectively, and summarized their clinical characteristics and echocardiographic features. Results: ①Infective endocarditis complicated with aortic bicuspid valve and connective tissue disease prefers to destroy MAIVF. ②The destruction of aortic valve were worse than mitral valve among these patients. ③The destruction of MAIVF could present as thickning, saccular formation and mass formation, which might cause the shunt between cardiac chambers. Conclusion: Echocardiography is the first choice for screening the destruction of MAIVF in infective endocarditis, which can evaluate the size, shape, location, blood flow of involved MAIVF and other complications of infective endocarditis, provides more detail information for surgery.
