Results: The successful rate of technique was 100%,no pulmonary stenosis and thrombus embolism occurred. The minimal diameter of PDA range from 3 mm to 8 mm (3.6±2.1 mm)in these patients, and the occluders 6 mm to 10 mm(5.4±3.6).
The mean minimum diameter of the PDA was 2.7± 0.9 mm(range, 1.5～ 4.0 mm)by angiography. . Patients included associating with pulmonary stenosis in three cases, ventricular septal defect in one case, aortic coarctation.
Methods Nineteen patients(9 male and 10 female,aged 4 to 37 years) with combined congenital heart diseases underwent transcatheter intervention therapy. Seven patients were of ventricular septal defect(VSD) and patent ductus arteriosus(PDA),5 patients of VSD and atrial septal defect(ASD),4 of ASD and PDA,2 of ASD and pulmonary stenosis(PS),1 of PDA and congenital coarctation of aorta.
Methods From January 2000 to October 2003,100 patient with congenital heart diseases underwent open heart surgery on beating h eart through minor incision of mid-sternal line,including 56 cases of ASD,40 ca ses of VSD,and 4 cases of pulmonary stenosis.
The pulmonary flow peak velocities(Vpa. max)of 13 patients with pulmonary stenosis(PS)and 37 patients with intracardiac septal defect(ISD)were analysed by color and continuous wave Doppler. The differences between the Vpa. max of PS and ISD and the effect of different ISD location as well as the size of ISD were estimated.
A 5—7 cm in the children or 9—11 cm in adult midline incision was made from the third rib to the base of xiphoid process. Cardiopulmonary bypass was established as usual. Abnormalities included ventricular septal defect in 66 cases,atrial sepal defect in 33,tetralogy of Fallot in 13,pulmonary atresia,endocardial cushions defect,pulmonary stenosis and unroofed coronary sinus syndrom in 1 case,respectively.
There were six patients with hypoplastic right ventricle including tricuspid atresia (Ⅰa type),tricuspid stenosis,pulmonary atresia with intact ventricular septum,pulmonary stenosis and ventricular septum defect.
2 children with branch pulmonary stenosis after total correction of tetralogy of Fallot (TOF) received angioplasty and stent placement, respectively. Another postoperative case with aortopulmonary collateral arteries (APCAs) angiorrhexis underwent transcatheter haemostasis.
