In all cases Figure diagnosed by ultrasound echocardiography 3 ~ 12mm spacing of ventricular septal defect associated with requiring surgical correction of cardiovascular malformations and severe pulmonary hypertension resulting from right to left shunt, the choice of the model of the occluder 4 ~ 14mm. Using the instruments for the Neu-Alpine 2000 color Doppler ultrasound transducer frequency 2 ~ 5MHz. 1.2 Methods of all patients with preoperative left ventricular long axis view, parasternal four-chamber view, five-chamber view and the bottom of my heart short axis and apical four-chamber view, five-chamber view, observe the VSD size, location, aortic annulus, tricuspid annulus,moncler outlet, the distance of the pulmonary valve ring; surgery to guide the placement of the delivery catheter and the occluder selection and release; postoperative observation of the occluder position, shape, with or without residual whether the impact of shunt occluder atrioventricular valve, aortic valve opening. 2 results of VSD + D1 cases,franklin marshall outlet, ultrasound measurements VSmm unable to establish the femoral artery, left and right ventricles, the femoral vein track to give up all the remaining 3O cases block the success of units: armed police in Henan Corps Hospital. Special examination; oracic Surgery, the Zhengzhou 450052VSD1 postoperative left bundle branch block, VSD after a small amount of residual shunt in 3 cases. 1 month after the review, there is still residual shunt in two cases. ree months after the review of only one cases of residual shunt width 1.2mm. 1 to 6 months after ultrasound follow-up, Am-paltzer blocking device fixed position, no shift and fall off, had no effect on the aortic valve, atrioventricular valve function. 3 discussion VSD is a common congenital heart disease. With heart disease involved in the development of treatment Transcatheter plugging the VSD gradually for clinical use. Sure, its efficacy in patients with pain, shorter recovery time, but the arrhythmia during surgery, the occluder loss and postoperative residual shunt, atrioventricular valve damage and other complications. To avoid complications, we believe that should be noted that: In addition to the muscle defect is easy to block after transcatheter closure of VSD is perimembranous defect. Perimembranous VSD adjacent to the aortic valve, the tricuspid valve and the atrioventricular conduction system, in order to avoid occluder placement, resulting in permanent damage of the secondary, preoperative echocardiography rigorous screening patients is necessary. Echocardiography multislice scanning VS ~ 10mm, the defect edge away from the aortic valve ring is greater than 2mm, with or without aneurysm of the membranous interventional treatment. VSD is too small and difficult to establish arteriovenous orbit, the group 1 patients defect 3mm block failure is such a case; of VSD is too large, the required occluder should be an impact on the functional organization of the defect around, especially tricuspid VSD, the defect of the lower edge of the septal leaflet often associated with organized under the tricuspid valve adhesion, block should pay attention to the atrioventricular bundle in the septal leaflet and its rear within the organization. e one cases VSD12mm, select on the 14th Amplatzer occluder closure, but after left bundle branch block may be related to this. We believe that the appropriate occluder than VSD, 1 ~ 2mm. Almost all patients in the surgical procedure of transcatheter closure of VSD had abnormal heart rhythms, ventricular arrhythmia, heart with catheter indoor operation
