Objective: Transcatheter treatment of children with congenital heart disease , and preliminary analysis of its safety, efficacy, and report the results of the recent follow-up ; explore common complication of interventional treatment of congenital heart disease and its treatment . Methods: 30 cases from October 2003 to March 2005 , living Anhui Medical University First Affiliated Hospital of Pediatrics, Department of Cardiology, who received the intervention treatment in children with congenital heart disease , age 7.46 ± 3.02 years old ( 20 months -14 years old) , 14 males and 16 females , of which two atrial septal defect ( 3 cases ) , patent ductus arteriosus four cases , ventricular septal defect in 19 cases , pulmonary valve stenosis four cases . The support and guidance of echocardiography and / or X-ray , domestic or imported occluder balloon line with congenital heart disease interventional therapy and balloon pulmonary valve plasty . After 3 days , 1 month , 3 months , 1 year follow-up, including physical examination , electrocardiogram , echocardiogram map content . Results : 4 cases of ventricular septal defect in children found that preoperative cardiac imaging is not suitable for interventional occlusion and give up after closure of ventricular septal defect children still medium-sized residual shunt be recovered. The other 25 patients successfully passing through the catheter interventional treatment . Mean operative time was 104 ± 63min (40-240min), the exposure time of 29 ± 23min ( 9 - 100min ) , 19 cases of preoperative cardiac enlargement in children are to restore normal range within 3 months after surgery , ultrasound hemodynamic markers returned to normal over the same period . Two cases trace residual shunt after 1 month , 3 months completely disappeared ; follow - up time of 8.6 ± 4.2 months ( January -15 ) , no occluder off , shift, hemolysis , endocarditis , atrioventricular block, valvular regurgitation , cardiac perforation , sudden death and other serious complications . Conclusion (1) under strictly controlled indications premise Transcatheter treatment of children with two atrial septal defect , ventricular septal defect , patent ductus arteriosus , pulmonary valve stenosis is a safe and effective treatment , with less trauma, hospitalization a short time, fewer complications, high success rate, surgical scars , etc. ; (2 ) guided by transthoracic echocardiography in children with congenital heart disease interventional therapy is feasible and effective way to avoid the inconvenience of transesophageal echocardiography and increase the risk of the suffering of children .
