Chinese expert consensus on surgical treatment of congenital heart disease (13): Congenital mitral valve malformation / 中国胸心血管外科临床杂志

@#To investigate the anatomical classification, diagnosis, indications, surgical methods, surgical techniques, intraoperative management, postoperative management and surgical efficacy of mitral valve malformation. Using the internationally used Delphi procedure, PubMed, Medline, The Cochrane Library, Wanfang and other databases were searched to review domestic and foreign literatures on congenital mitral valve deformity from January 1940 to February 2020, and select the ones of higher quality as evidence. In addition, with regard to the multiple disputes in the diagnosis and treatment of congenital mitral valve, experts from pediatric cardiac surgery and related disciplines have been convened for discussion for many times, and finally the following consensus has been formed to guide the clinical treatment and provide theoretical and technical guidance for the surgical treatment of congenital mitral valve malformation in China.

Echocardiographic diagnosis of congenital mitral valve malformation / 中华超声影像学杂志

Objective To investigate the clinical value of the echocardiography in the diagnosis of congenital mitral valve malformation and summarize its occurrence and type associated with other cardiac malformations.Methods The echocardiographic image data of 101 patients with congenital mitral valve malformation were retrospectively analyzed,the characteristics of different types were summarized and compared with operation results,CT,cardiac catheterization,transesophageal echocardiography,as well as the data of echocardiographic follow-up.Results Among 101 patients with echocardiographic examination showed mitral valve congenital malformation,63 cases were isolated valve set malformation (62.4％),and multiple valve set malformation were found in 38 cases (32.7％).In another side,39 cases were of single mitral valve malformation (38.6％),while 62 patients combined with other type cardiac malformations (61.4％).No significant difference of dynamic change was shown between patients with solitary and multiple malformation of mitral valve (P ＞0.05).Conclusions Echocardiography can display congenital mitral valve malformation in a fast,robust,real-time way.It has an important clinical value in the diagnosis of congenital mitral valve malformation.
