Background: Patent ductus arteriosus (PDA) can be treated by transcatheter device closure . This study is our experience in Tanta and Benha University Hospitals
Aim: Initial experience with transcatheter closure of (PDA) using different types of devices .To evaluate the feasibility , efficacy and safety of transcatheter closure of PDA in pediatric age group patients on basis of short-term follow up
Patients & Methods: This prospective observational study included 26 children with PDA ; 21 female and 5 males with age 30.2 ± 27.6 months , weight 12.8 ± 6.6 Kg and body surface area 0.54 ± 0.2m2. Aortic angiogram was performed to evaluate the duct size and shape for appropriately choosing the occluder type and size. A second aortic angiogram was performed 10 min after device deployment. Every patient had echocardiographic assessment before and after ductus closure. Follow up was done 24 hour, 1 week and 3 months post-intervention. Evalution included immediate and remote complications, residual shunt, Left ventricle dimensions, left atrium / aorta ratio and pressure gradient along descending aorta and left pulmonary artery.
Results: No complications like thrombus formation, blood loss or infective endocarditis in any case were reported after successful ducts closure. Complete ductus closure was achieved in 77% of cases by 24 hours post- intevension, and in 96.15 % after three months. The left side dimensions had significantly decreased ; the left ventricular end diastolic diameter (LVEDd) decreased from 33.28±4.92 mm pre-intervention to 26.54±4.53 after 3 months (P |
