Cardiac surgical procedures and conjoined interventional catheterization performed in 23 children with congenital heart disease

To summarize the experience of interventional catheterization conjoined with cardiac surgical procedures perfomed in 23 children with congenital heart disease (CHD).Methods 12 cases with residual patent ductus arteriosus after surgical ligation and 2 postoperative cases with severe cyanosis CHD with leftover ventricular septal defect (VSD) received transcatheter closure procedures.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.6 cases underwent interventional catheterization in the preoperative period.5 cases with transposition of great arteries (TGA) underwent balloon atrial septostomy (BAS) before artery switch procedure and 1 case of TOF underwent APCAs transcatheter occlusion before total correction.Results All cases with residual left to right shunts after surgery were occluded by transcatheter therapy.Interventional catheterization procedure relieved stenosis of branch pulmonary artery in postoperative case with TOF.Haemorrhage was stopped with embolization of ruptured APCAs.Hypoxia and acidosis improved after BAS therapy in 5 cases with TGA and intact ventricular septum and 3 survived from following artery switch procedure while 2 died.The APCAs was transcatheter occluded before TOF total correction.Conclusion Interventional catheterization therapy conjoined with cardiac surgical procedure was an effective and essential method in some postoperative CHD cases and in some of complex cyanosis CHD cases.8 refs,3 figs.
