Abstract:
Objective To discuss the morphological features and diagnosis of congenial double orifice mitral valve (DOMV) deformity by echocardiography.Methods Twenty consecutive patients were examined.The changes of the morphology and flow dynamics of DOMV were studied,and other congenital cardiac abnormalities were also observed.These results were compared with those of surgery.Results Thirteen cases of adult patients were all with significant hemodynamic abnormalities,and underwent mitral replacement.One case of school child with muscular ventricular septal defect underwent mitral replacement because of obvious hemodynamic changes.Six cases were under 2 years old,2 cases with complete endocardial cushion defect accompanied with pulmonary hypertension,1 case with partial endocardial cushion defect accompanied with coarctation of the aorta underwent corrective operation.No significant hemodynamic abnormalities in 2 cases,1 case was associated with coarctation of the aorta and patent ductus arteriosus,the other patient with membranous ventricular septal defect.Severe stenosis in 1 case with papillary muscle dysplasia,because there was no suitable operation and take conservative therapy.Seventeen cases were confirmed by the results of open-heart surgery.Conclusions Echocardiography can provide an accurate method to diagnose DOMV and evaluate the hemodynamic changes.
