This female predominance can be explained by the increased prevalence of ostium secundum
atrial septal defects and rheumatic heart disease in females.
Congenital heart diseases were seen in 7 neonates (28%), of which atrial septal defect (ostium secundum
) was the most common type (4/7 neonates).
interatrial septal defect, with inverted shunt right to left at color Doppler and with a shunt gradient situated at 48 mm Hg.
Echocardiography (figure 2) showed a 3 mm ostium secundum
atrial septal defect and a fenestrated atrial septal aneurysm with its excursion towards the left atrium (12 mm) with a right to left shunt.
* Any primary or secondary (up to 25 total) International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) discharge diagnosis codes 740-759, with the following exceptions: 1) when persistent fetal circulation (747.83) or balanced autosomal translocation in a normal person (758.4) were the only codes in this range recorded for the discharge; or 2) when patent ductus arteriosus (747.0) or ostium secundum
type atrial septal defect (745.5, which includes patent foramen ovale as well as actual atrial septal defects) were the only defects coded in a preterm infant or an infant aged <28 days.
Percutaneous device closure is an alternative to surgical closure only in patients with ostium secundum
ASDs with the appropriate anatomic characteristics.
(1,2) The 2 mm P waves in lead [V.sub.2] indicate right atrial enlargement, (3) helping to confirm right ventricular enlargement and to suggest a fossa-ovalis type (ostium secundum
) atrial septal defect.
The later was gradually occluded by the further enlargement of cushions but before complete closure, the number of perforations appeared within the septum which coalesced to form ostium secundum
. The septum secundum which appeared right to the septum primum completely divided the atria into right and left parts.
Los casos reportados en la literatura abarcan malformaciones de todo tipo, y dentro de los mas frecuentes se encuentran la coartacion aortica, los defectos en el tabique auricular de tipo seno venoso y otros, como los defectos del tabique interventricular de tipo muscular o interauricular de tipo ostium secundum
, arco aortico interrumpido y defectos completos en el tabique auriculoventricular, que son los de menor incidencia [11-13].
Further investigations revealed absence of secondary sexual characters, primary amennorhea, widely spaced nipples, hypoplastic uterus, underdeveloped ovary, cardiac examination including the echocardiography revealed atrial septal defect of ostium secundum
type, but no webbed neck.
