What heart defects are associated with DiGeorge syndrome?

The associated cardiac defects include: 1) right or cervical aortic arch with or without aberrant left subclavian artery; 2) hypoplasia or absence of the infundibular septum; 3) absence of the pulmonary valve; 4) discontinuity and diffuse hypoplasia of the pulmonary arteries.

What are Conotruncal heart defects?

Conotruncal heart defects are structural abnormalities of the cardiac outflow tract. This means that the pathway for the blood to leave the heart and circulate to the body or to the lungs is disrupted. Tetralogy of Fallot (TOF)

Does 22q11 affect life expectancy?

DiGeorge syndrome (22q11 deletion) is a rare primary immunodeficiency disease in children that causes low levels of a special type of white blood cell called a T cell that fights infections. In about 1-2% of cases, some children have a life expectancy of two or three years.

Is tetralogy of Fallot associated with DiGeorge syndrome?

Children with tetralogy of Fallot are more likely to have chromosome disorders, such as Down syndrome, Alagille syndrome, and DiGeorge syndrome (a condition that causes heart defects, low calcium levels, and poor immune function).

Is 22q a disability?

Many children with 22q11. 2 deletion syndrome have developmental delays, including delayed growth and speech development, and some have mild intellectual disability or learning disabilities. Older affected individuals have difficulty reading, performing tasks involving math, and problem solving.

What is the long term outlook for a child with DiGeorge syndrome?

Outlook for DiGeorge syndrome Most children survive into adulthood. As someone with DiGeorge syndrome gets older, some symptoms, such as heart and speech problems, tend to become less of an issue. However, behavioural, learning, and mental health problems can continue to affect their daily life.

What type of VSD is seen with Conotruncal defects?

An intramural ventricular septal defect (VSD) is a residual VSD that can be seen after surgical repair of conotruncal defects that involve patch closure of a VSD from the left ventricle to a great artery.

What is the Conotruncal septum?

Conotruncal septum:the septum that divides the conus cordis into the outflow tracts (infundibulum of the right. ventricle [conus arteriosus] and aortic vestibule) as well as the truncus arteriosus. Ductus arteriosus: shunts blood from the left pulmonary artery to the descending aorta, by-passing the lungs.

Is 22q11 a disability?

Many children with 22q11. 2 deletion syndrome have developmental delays, including delayed growth and speech development, and some have mild intellectual disability or learning disabilities.

What are the 4 defects found in tetralogy of Fallot?

Tetralogy of Fallot is a combination of four congenital heart defects. The four defects are a ventricular septal defect (VSD), pulmonary stenosis, a misplaced aorta and a thickened right ventricular wall (right ventricular hypertrophy).

What is the Conotruncal region?

The cardiac OFT, comprised of the conus or bulbus cordis and the truncus arteriosus (together called the conotruncal region), is a rapidly remodeling structure during embryogenesis at the arterial pole of the heart, as it connects the embryonic ventricles to the aortic sac [3].

Is VSD a serious heart condition?

In adults, VSDs can be rare, but serious, complication of heart attacks. These holes do not result from a birth defect.

How is aorticopulmonary septum formed?

The spiral orientation of the ridges results in a spiral aorticopulmonary septum when these ridges fuse. This septum divides the bulbus cordis and the truncus arteriosus into two channels, the aorta and the pulmonary trunk.

Can babies live with tetralogy of Fallot?

Most children who have had a tetralogy of Fallot surgical repair will live healthy lives. Activity levels, appetite and growth will eventually return to normal in most children. Your child’s cardiologist may recommend that antibiotics be given to prevent bacterial endocarditis after discharge from the hospital.

What is the difference between truncus arteriosus and conus arteriosus?

The caudal end of the bulbus cordis gives rise to the smooth parts (outflow tract) of the left and right ventricles (aortic vestibule & conus arteriosus respectively). The cranial end of the bulbus cordis (also known as the conus cordis) gives rise to the aorta and pulmonary trunk with the truncus arteriosus.
