多平面经食管超声心动图在成人房间隔缺损介入治疗中的应用

探讨多平面经食管超声心动图在成人房间隔缺损介入治疗中的价值。方法应用ＭＴＥＥ行术前筛选、术中监测和术后随访。结果３６例经ＭＴＥＥ诊断为各型ＡＳＤ，１２例符合治疗适应证（３３％）。１８例用球囊导管探测ＡＳＤ大小。ＭＴＥＥ的声像直径和球囊探测的伸张直径高度相关，伸张直径＝１．２１（ＭＴＥＥ声像直径）－０．１３。

Application of multiplane transesophageal echocardiography in the interventional therapy of the adult atrial septal defect

Objective To study the value of the multiplane transesophageal echocardiography(MTEE) in the interventional therapy of the adult atrial septal defect(ASD).Methods MTEE was used for screening prior to the operation,monitoring during the operation and postoperative follow up.Results Thirty six patients were diagnosed as distinguished types of ASD.12 cases accorded with the indication of the operation(33%).The sizes of ASD were detected by the catheters with balloon in 18 cases.There were significant correlation between the sonographic diameter by MTEE and the extensible diameter by the catheter with balloon(r= 0.95 ,P< 0.001 ).Extensible diameter(cm)= 1.21 (MTEE diameter)- 0.13 .The therapy of closure ASD was successful in 11 cases.Conclusions MTEE possesses an originality in selecting the indications,monitoring the catheter with balloon and occluder,and showing the small residual shunts.The extensible diameter may be estimated by MTEE sonographic diameter to improve the therapeutic efficiency.
