Patent Ductus Arteriosus Patent Ductus Arteriosus persistence communication Definition : PDA represent postpartum persistence of the embryological communication between distal area of Aortic Isthmus and left Pulmonary Artery. Simptoms:  vary with the size of the defect and whether the baby is full-term or premature.  fatigue  fatigue while eating  malnutrition  growth deficiency  tachypnea  tachycardia  Sweating  Sweating during crying or eating Complications : congestive heart failure bronchopulmonary dysplasia necrotizing enterocolitis intracranial hemorrhage renal insuficiency

RISK FACTORS/TREATMENT

OBJECTIVES T he aim of my study is to evaluate by a descriptive survey the PDA records of Cardiovascular Diseases and Transplant Institute-Tg.Mures and to state some conclusions related to clinical and therapeutic approach of this pathology. Points of interest:  Mean age of the patients at the surgical intervention time  Gender distribution  Prevalence association of PDA with other Congenital Heart Defects  Prevalence association of PDA with other Congenital Heart Defects depending on gender  Mean weight /height at the time of surgery time  Association between Down Sindrom and PDA+other malformations;  The frequency of different Congenital Heart Defects that require maintaining Patency of the ductus.

DISCUSSION

CONCLUSIONS 1.Gender equality regarding the incidence of PDA; 2. The association between PDA+FT,PDA+Aortic Coarctation and PDA+TGA have a higher frequency in males than in females 3. Isolated PDA is more frequent in females than in male; 4. The most frequent CHD associated with PDA are :PDA+ASD,PDA+VSD,PDA+TGAand PDA+AoCo.; 5.Some of the CHD that are less associated with PDA are:Hypoplasia of Aortic Arch,Tricuspid Insufficiency,Tricuspid/Mitral Stenosis; 6.Down Sindrome has a statistical singnificance for association with PDA+Pulmonary Hipertension and PDA+ Atrioventricular comun ductus; 7.The association between Ductal Dependent Circulation and: Fallot Tetralogy,Aortic Coarctation and Pulmonary Valve/Branch Atresia has an important statistical significance 1.Gender equality regarding the incidence of PDA; 2.
