چکیده

STUDY QUESTION Are the risks of hypoplastic left heart syndrome, transposition of great arteries, tetralogy of Fallot (TOF) and coarctation of the aorta increased in infants conceived by different assisted reproductive techniques (ARTs)? STUDY ANSWER ARTs, and particularly intracytoplasmic sperm injection (ICSI), are specifically associated with a higher risk of TOF. WHAT IS ALREADY KNOWN ARTs are associated with an increase in the overall risk of birth defects. The risk for congenital heart defects (CHDs) associated with ARTs has been evaluated as a whole but there is limited information on the risks for specific CHDs. STUDY DESIGN, MATERIAL AND METHODS: We conducted a case-control study using population-based data from the Paris registry of congenital malformations for the period 1987-2009 and a cohort study of CHD (EPICARD) on 1583 cases of CHDs and 4104 malformed controls with no known associations with ARTs. ARTs included ovulation induction only, IVF and ICSI. RESULTS Exposure to ARTs was significantly higher for TOF than controls (6.6 versus 3.5%, P = 0.002); this was not the case for the other three CHDs. ARTs (all methods combined) were associated with a 2.4-fold higher odds of TOF after adjustment for maternal characteristics, paternal age and year of birth [adjusted odds ratios (OR): 2.4, 95% confidence interval (CI): 1.5-3.7] with the highest risk associated with ICSI (adjusted OR: 3.0, 95% CI: 1.0-8.9). No statistically significant associations were found for the other CHDs. LIMITATIONS Our study cannot disentangle to what extent the observed associations between the risk of TOF and ARTs are due to causal effects of ARTs and/or the underlying infertility problems of couples who conceive following ART. IMPLICATIONS The developmental basis of the specific association between the risk of TOF and ARTs need to be further investigated.

O-26: Comparison of Congenital Malformation of Infants Conceived by Assisted Reproductive Techniques versus Infants with Natural Conception in Tehran

Background: In many countries, 1% to 3% of newborn infants are conceived by Assisted Reproductive Techniques (ART). Despite the success of ART, there is concern about the risk of congenital malformations among these infants. We report our experience to determine whether use of ART is associated with an increase in major congenital malformations or adverse pregnancy outcomes Materials and Method...

I-42: Do Birth Defects Increase with Assisted Reproductive Technologies

Assisted reproductive technologies (ART) like in vitro fertilization have enabled many infertile couples to achieve pregnancy. Although ART pregnancies have long been known to be characterized by increased rates for certain maternal complications, these complications are predictable based on the mother’s more advanced age - increased medical complications like hypertension or diabetes mellitus....

Assessing the role of multiple pregnancies in the association between tetralogy of Fallot and assisted reproductive techniques: a path-analysis approach

BACKGROUND Assisted reproductive techniques (ART) are associated with a higher risk of tetralogy of Fallot (TOF) and multiple pregnancies may be associated with a higher risk of congenital anomalies. We assessed the extent to which the association between ART and risk of TOF may be mediated by the higher risk of multiple pregnancies associated with ART. METHODS We conducted a case-control stu...
