Article: Maternal transmission of congenital heart diseases: new recurrence risk figures and the questions of cytoplasmic inheritance and vulnerability to teratogens.
[show abstract] [hide abstract]
ABSTRACT: A review of 8 studies involving 3,996 offspring of parents who have congenital heart disease revealed that the risk for all defects was substantially higher if the affected parent was the mother rather than the father. The risk ratio ranged from a high of 6.39 for aortic stenosis to a low of 1.48 for patent ductus arteriosus, and the ratio was statistically significant in aortic stenosis (p = 0.025) and ventricular septal defect (p less than 0.001). Despite the relatively large number of cases, there were still too few patients to reveal statistical significance for a malformation such as atrioventricular canal, in which there were 5 affected offspring among 36 children of mothers who had atrioventricular canal and no affected children among 16 offspring of affected fathers (p = 0.12). The possible reasons for the preponderance of affected offspring of mothers with a congenital heart disease was studied in the context of various modes of inheritance and maternal physiology. The preliminary conclusion is that although many familial cases of congenital heart disease are compatible with multifactorial inheritance and vulnerability to teratogens, an important subset of cases, particularly in some high-risk families, may be better explained by cytoplasmic inheritance than by multifactorial or mendelian modes. Current genetic counseling should take into account the differences in risk to offspring of affected mothers while confirmation and further investigation proceeds.The American Journal of Cardiology 03/1987; 59(5):459-63. · 3.37 Impact Factor -
Article: A second-generation study of 427 probands with congenital heart defects and their 837 children

ABSTRACT: Objectives. This study attempted to answer the question, Do mothers with congenital cardiovascular defects have more affected children than fathers with cardiac anomalies?Background. In the 1950s to 1960s, concern was expressed about the safety of pregnancy in women with cardiac anomalies and the possibility of inheritance.Methods. In a prospective study over 25 years, 236 women with cardiac defects were followed through pregnancy, and their 418 offspring were examined during their 1st 3 years. A high incidence of congenital cardiac malformations was noted. Then, a retrospective study of 191 men from the same clinic group and their total family (419 children) was performed to compare the incidence of affected children between the maternal study and this subsequent paternal study.Results. Of 837 live children of these 427 probands, 14.1% (118) had a congenital heart defect (13.4% in the maternal study, 14.8% in the paternal study). There was no correlation with the surgical status of the proband. Concordance was somewhat greater among the children of affected mothers compared with those of affected fathers. Included in these studies were 31 high risk probands, 10 with genetic syndromes and 21 who had an affected sibling. Respectively, 53% and 41% of their children had cardiac anomalies, with a concordance > 50%; three fourths of these children had moderate to severe anomalies.Conclusions. The incidence of congenital heart defects in the children was not statistically different between the maternal and paternal studies. With removal of the high risk probands from the total study group, the risk of one affected parent having a child with a cardiac anomaly was 10.7%. Of the entire 837 children, only 7.5% had moderate or severe defects.Journal of the American College of Cardiology 06/1994; · 14.16 Impact Factor
