OBJECTIVE

To investigate the methods of interventional catheterization for combined congenital heart disease and to evaluate its efficacy in children.

METHODS

From March 1994 to December 2003, 15 cases (6 boys, 9 girls) underwent transcatheter intervention for combined congenital heart diseases. The procedure of transcatheter intervention was as follows: for pulmonary stenosis (PS) and atrial septal defect (ASD) or patent ductus arteriosus (PDA), PBPV first, occlusion of ASD or PDA later; for coarctation of aorta (COA) and PDA, dilation of COA first, occlusion of PDA 4-15 months later; for aortic stenosis (AS) and PDA, PBAV first, occlusion of PDA later; for ventricular septal defect (VSD) and PDA, all occlusions with detachable coils.

RESULT

Transcatheter intervention for combined congenital heart diseases was successful in all patients. There was no residual shunt after occlusion immediately apart from 2 cases of PDA which were little residual after occlusion immediately. Follow-up for (3.57 +/-2.61) years, the systolic pressure gradients across pulmonary valve and coarctation were normal by ultrasonic or transcatheter, except AS. There was 3 cases presented postoperative complications: 1 with mechanical haemolysis, 1 with fall off of coil and 1 with arterial embolism, respectively.

CONCLUSION

Transcatheter intervention for combined congenital heart diseases could obtain satisfactory results with appropriate indications and procedure manipulations.
