full title of the research:
Closure of congenital heart defect using A fully biodegradable polydioxanone and poly L Lactic Acid occluder and scaffold for (atrioventricular (AV) defect closure , patent ductus arteriosus (PDA) occluders , left atrial appendage (LAA) occluders and patent foramen ovale (PFO) occluders.
***objectives :
Closure of some congenital heart defects using biodegradable poly L Lactic acid and polydioxanone
With catheterization or transthoracic instead of open heart surgery .
***another Special Objective:
Closure of some hearts defects using ( polydioxanone ,poly L lactic acid- copolymer (.
( PDO/PLLA co-polymer ).
***for LR, use 10 references ( if possible), you can use the 2 paper attached in addition to the link at the end of this description ,this refs shoud be on subject related to PLLA , PDO, PLLA/PGA , PDO/PLLA CO-polymer, and applied on congenital heart defects (for (atrioventricular (AV) defect closure , patent ductus arteriosus (PDA) occluders , left atrial appendage (LAA) occluders and patent foramen ovale (PFO) occluders )
