Mitral valve prolapse is frequent in childhood. The use of two-dimensional echocardiography may enable more accurate diagnosis and assessment of the degree of valve involvement. Twenty five (1.9%) of all children studied by two-dimensional echocardiography fulfilled the diagnostic criteria for mitral valve prolapse. In 48% it was associated to a different congenital heart as normality. The apical four chamber and parasternal long and short axis views were used, and cases were graded according to the severity of the prolapse. Diagnosis was made in 44% of cases by the apical four chamber view, which was the best projection to detect the abnormality. Cases of moderate and severe prolapse were also detected in the parasternal long axis view. All patients were asymptomatic but they were all controlled detect progression to mitral insufficiency of the appearance of other complications.
二尖瓣脱垂在儿童期很常见。二维超声心动图的应用可能有助于更准确地诊断和评估瓣膜受累程度。在接受二维超声心动图检查的所有儿童中，有25例（1.9%）符合二尖瓣脱垂的诊断标准。其中48%与其他先天性心脏病有关，而非正常情况。采用心尖四腔心切面以及胸骨旁长轴和短轴切面，并根据脱垂的严重程度对病例进行分级。44%的病例通过心尖四腔心切面做出诊断，该切面是检测异常的最佳投照位置。胸骨旁长轴切面也能检测到中度和重度脱垂病例。所有患者均无症状，但都进行了监测，以发现是否进展为二尖瓣关闭不全或出现其他并发症。
