Clinical and echocardiographic examinations were performed on 100 clinically stable, newborn baby girls. Mitral valve prolapse was noted on the echocardiograms of seven babies. Three subjects had systolic clicks, two of whom had systolic murmurs following the click. The four other babies who had echocardiographic evidence of mitral valve prolapse had no abnormal auscultatory signs. Of the 93 babies without evidence of mitral prolapse, 91 had normal echocardiograms and auscultatory features; one was noted to have a murmur consistent with a ventricular septal defect, and another had an eccentric aortic valve on the echocardiogram which was suggestive of a bicuspid aortic valve. Serial studies on our group of subjects will yield useful information regarding the natural history of mitral valve prolapse.
对100名临床状况稳定的新生女婴进行了临床和超声心动图检查。在7名婴儿的超声心动图上发现二尖瓣脱垂。3名受试者有收缩期喀喇音，其中2名在喀喇音后有收缩期杂音。另外4名有二尖瓣脱垂超声心动图证据的婴儿没有异常听诊体征。在93名无二尖瓣脱垂证据的婴儿中，91名超声心动图和听诊特征正常；1名被发现有与室间隔缺损一致的杂音，另1名在超声心动图上有偏心主动脉瓣，提示二叶式主动脉瓣。对我们这组受试者的系列研究将产生关于二尖瓣脱垂自然病史的有用信息。
