CLINICAL APPLICATION OF THE SECOND GENERATION OF AMPLATZER PATENT DUCTUS ARTERIOSUS OCCLUDER IN THE INTERVENTIONAL CLOSURE OF CONGENITAL HEART DISEASE AND CASE SERIES

Background: Some patients with structural heart disease are typically treated or improved by minimally invasive surgeries. Aim: To summarize the efficacy and experience in treatment of congenital (CHD) using second generation Amplatzer patent ductus arteriosus (ADO- II) occluder. Methods: A total 37 who were admitted to cardiac surgery department our hospital from June 2014 April 2019 included. After preoperative echocardiography clinical screening, intraoperative transthoracic echocardiography, cardiovascular angiography, postoperative was carried out evaluate incidence residual shunt location morphology ADO-II occluder, as well complications. Results: All successfully There 27 (73%) cases (PDA), 5 (13.5%) ventricular septal defect (VSD), 1 case (2.7%) VSD combined PDA, aortopulmonary collateral arteries right coronary artery-right atrial fistula, 2 (5.4%) recanalized after ligation main pulmonary artery. had no obvious abnormality ECG reexamination one month surgery; The x-ray showed displacement shedding, long-term significant found echocardiography. No death reported. Conclusions: occluder is relatively simple operate, a high success rate few complications, it can be applied not only PDA occlusion but also other CHDs, making worthy further promotion under premise grasping indicators interventional therapy.
