Objective: To investigate the methods of combined percutaneous transcatheter interventions for congenital heart disease with multiple defects and to evaluate its efficacy in children.
Methods: 17 cases (10 boys, 7 girls, ages 3 days-16 years, body weight 3.4-35 kg) that underwent multiple transcatheter interventions for congenital heart disease with multiple defects were retrospectively analyzed and presented. The sequence of the interventions was planned according to the nature and localization of the defects.
Result: Additional PDA closure (6) was performed following VSD closure (2), ASD closure (1), coarctation angioplasty (2), pulmonary balloon valvuloplasty (1); coarctation angioplasty (5) was performed following aortic valvuloplasty (3), VSD closure (1) and balloon atrial septostomy (1) for transposition of great arteries. Ductal stent implantation was the combined procedure in 2 patients after pulmonary valve perforation and/or pulmonary balloon valvuloplasty with hypoplastic right ventricles. Other combined procedures were ASD closure after pulmonary balloon valvuloplasty (1); pulmonary balloon valvuloplasty after aortic balloon valvuloplasty (1); coil embolization of a pulmonary lobar sequestration after coarctation angioplasty (1); and palliative pulmonary balloon valvuloplasty after recanalization and angioplasty of the systemic-pulmonary shunt in tetralogy of Fallot (1). There was no mortality or major morbidity.
Conclusion: For the treatment of combined congenital cardiovascular defects, multiple transcatheter interventions in the same session are feasible, safe and effective with satisfactory good results. Second intervention may be performed as complementary or substantive to the first procedure.
