13. Unknown syndrome: abnormal facies, congenital heart defects, hypothyroidism, and severe retardation.
We present a female infant with (1) abnormal facies: microcephaly, blepharophimosis, small, low set, posteriorly rotated ears, bulbous nose, carp shaped mouth, micrognathia; (2) congenital heart abnormalities: large atrial and ventricular septal defects; (3) congenital hypothyroidism; (4) severe global retardation.

14. Genetics and congenital heart disease1
In isolated congenital heart disease genetic factors have been shown from family studies, individual pedigree analyses, the frequency of consanguinity, examination of data from twins, and possibly from cytogenetics. In defects of the atrial septum, where data are most complete, genetic factors appear to be important, particularly in secundum atrial septal de

15. Unknown syndrome: holoprosencephaly, congenital heart defects, and polydactyly.
We present a stillborn male infant with premaxillary agenesis, bilateral microphthalmos, alobar holoprosencephaly, hydrocephalus, ventricular and atrial septal defects, small penis, bilateral cryptorchidism, and bilateral upper limb postaxial polydactyly.

16. Type and frequency of cardiac defects in embryofetal alcohol syndrome. Report of 16 cases.
Within a period of 3 years, 56 infants and children with embryofetal alcohol syndrome have been detected and examined for heart defects. All children were from mothers who had been addicted to alcohol even during pregnancy and they showed a typical pattern of malformations, as described by Lemoine et al. (1968) and Jones et al. (1973). In 16 cases cardiovasc

17. Comparison of interventricular septal motion studied by ventriculography and echocardiography in patients with atrial septal defect.
Abnormal systolic interventricular septal motion is an echocardiographic manifestation of right ventricular volume overload. In order to determine the anatomical basis for this echocardiographic finding, septal motion recorded by left lateral or left anterior oblique ventriculograms was compared with echocardiography ventricular septal motion. Thirteen patie

18. Detection of ostium secundum atrial septal defects by transoesophageal cross-sectional echocardiography.
Transoesophageal cross-sectional echocardiography has special advantages when investigating the interatrial septum which is imaged perpendicularly without echo dropouts from an oesophageal transducer position. The technique was successfully used in 19 out of 20 patients (95%) with an ostium secundum atrial septal defect and in 30 control subjects. In all of

19. Echocardiographic Evaluation of Left Ventricular Function, Mass and Wall Stress in Children with Isolated Ventricular Septal Defect
M-Mode echocardiography was performed in 22 normal children and 22 children with ventricular septal defects. Left ventricular and left atrial chamber dimensions and wall thicknesses were measured in all patients. Utilizing these data, indices of left ventricular function were derived: shortening fraction, velocity of fiber shortening, peak diastolic fiber le

20. Atrioventricular septal defect in prenatal life.
In a series of more than 3500 pregnancies referred for fetal echocardiography, 29 cases of atrioventricular septal defect were detected in the fetus. There was a chromosomal anomaly in 14 of these cases, left atrial isomerism in 12, and right atrial isomerism in two. Complete heart block was found in 11 of the cases with left atrial isomerism. Many associate

21. Mitral valve in secundum atrial septal defects.
The mitral valve in 15 of 16 adult hearts with unclosed secundum atrial septal defects showed a consistent abnormality consisting of thickening of the medial half of the anterior cusp and some fusion of adjacent chordae. Histologically the lesion is a surface fibrosis without vascularisation or myxomatous change to suggest a rheumatic or floppy valve. The hi

22. Fetal complete heart block.
In a series of over 6000 patients referred for fetal echocardiography during an eight year period, 37 fetuses were found to have complete heart block. There were 16 cases of isolated heart block and 21 cases associated with structural heart disease. All mothers of fetuses with isolated complete heart block had evidence of circulating syndrome Sjögren A anti

23. Conduction disturbances after surgical correction of ventricular septal defect by the atrial approach.
Conduction disturbances have been documented after correction of ventricular septal defects by the ventricular route. Recently, repair of the ventricular septal defect has been through the right atrium to overcome damage to the conduction system and a right ventriculotomy. Thirty-nine children with ventricular septal defects under the age of 5 years were ope

24. Identification of congenital cardiac malformations by echocardiography in midtrimester fetus.
Fetal echocardiograms were performed in 21 pregnancies before midtrimester termination. All fetal heart specimens were collected and studied morphologically. Eighteen had been diagnosed as normal echocardiographically and this was confirmed anatomically. Deficiency of the atrial septum was suspected in one, and primum and secundum atrial septal defects were
