  Objective Prenatal diagnosis of total anomalous pulmonary venous connection (TAPVC) is challenging even for experts.We sought to explore whether the use of spatiotemporal image correlation (STIC) can supply additional information with respect to conventional fetal echocardiography in the prenatal diagnosis of TAPVC.Methods Twenty-two cases diagnosed as TAPVC received fetal echocardiography examination from April 2009 to December 2013.Four-dimensional volumes from 16 cases of suspected TAPVC by conventional echocardiography at our hospital.Echocardiographic characteristics were compared with the results of postnatal work-up and pathology.Results Prenatal diagnosis was made at a mean gestational age of 26.6 (range 21 to 36) weeks.TAPVC was found in 22 cases by fetal echocardiography; four cases were isolated TAPVC, eighteen TAPVC had associated cardiac anomalies.Among them, nine cases were supracardiac types, five cases were infracardiac types and eight cases were intracardiac types.Twelve true positive cases of TAPVC were confirmed after birth or pathology.The fetal echocardiographic characteristics of 22 fetuses with TAPVC included absent insertions of pulmonary veins in the LA, increased distance between left atrium (LA) and descending aorta, presence of a confluence behind the left atrium, increased angle between left and right pulmonary veins.4D ultrasound with STIC clearly visualized the anomalous PV confluence and/or the draining vertical vein in all sixteen cases examined.Conclusion There are fetal echocardiographic characteristics of TAPVC.Conventional fetal echocardiography plays an important role in prenatal diagnosis of TAPVC.4D ultrasound with STIC should be proposed to identify abnormal venous drainage at the screening level, thus supplying additional information over that provided by 2D fetal echocardiography.

目的 使用术中三维超声技术检测二尖瓣成型前后二尖瓣环空间构型的变化.方法 选择单纯二尖瓣退行性变导致重度瓣膜反流患者,无其他合并心脏疾病.入院后体表二维超声检测,在手术室术前经食管三维超声检测复查二尖瓣反流部位和程度,以及二尖瓣瓣环空间构型,包括二尖瓣环环径、横径、纵径、瓣环高度、前叶合后叶非平面夹角等,并初步确立手术成型方法.术后同样进行三维食管超声检测相同内容.结果 入选二尖瓣成型病例36例,
患者男性,70岁,主因间断发作性心悸10年,加重三年,为行射频消融术于2013.7.25来我院就诊.患者既往于1998年在外院行肾移植术.由于该患者曾行肾移植手术的特殊性,因此,对于该患者围手术期的护理,要格外注意对患者肾脏的保护,避免射频消融术对患者移植肾的损害.主要从对移植肾的护理,皮肤的护理,心理护理,用药指导,饮食指导,疼痛与舒适的护理,健康宣教等方面进行了详细的护理指导,有效的减少了患者
