Is tetralogy of fallot hereditary?

Is tetralogy of fallot hereditary?

Depends on variables: Most cases of complex congenital heart disease happen in a sporadic manner. The general risk of a parent with a chd having a child in these sporadic forms is about 6%.This is not specific to the same defect but includes all defects.When it is part of an autosomal disorder or chromosome deletion syndrome, the risks are higher. ...Read more

Tetralogy Of Fallot (Definition)

A heart defect that features four problems: a hole between the lower chambers of the heart; an obstruction between the heart and the lungs; when the aorta (blood vessel) covers the hole in the lower chambers of the heart; and when the muscle surrounding the lower right chamber ...Read more

Tetrology of fallot with pulmonary artery?

Tetrology of fallot with pulmonary artery?

Congenital defect: Tetralogy of fallot is a congenital defect of the heart in which the there is a hole in the ventricular septum ( wall that separate the two ventricles) of the heart, overriding of the septal defect by the aorta and atresia of the pulmonary artery, it causes mixing of arterial blood with venous blood , therefore hypoxemia ( low level of oxygen) to the general circulation, pulmonary HTN may occur. ...Read more

Will PDA (patent ductus arteriosus) help with TOF (tetralogy of fallot)?

Sometimes: In Tetralogy of Falot, blood flow to the lungs may be restricted. As there are various degrees of restriction, there may be a need for more blood flow to the lungs. This situation may be helped by maintaining an open PDA. However if the pulmonary valve restriction is not severe, then an open PDA is not necessary. The cardiologist can draw this out for you. ...Read more

What is tetralogy of fallot?

TOF: Tetrology of Fallot is a congenital heart defect consisting of defect in the wall between the ventricles, stenosis of the pulmonary artery, enlargement of the right ventricle, and an abnormally placed aorta. It occurs in about 5 out of every 10,000 babies. The defect affects boys and girls equally. It is corrected with open heart surgeries. ...Read more

Could tetralogy of fallot be genetic?

Could tetralogy of fallot be genetic?

Yes: Definitely, some cases of tetralogy of fallot have a genetic component. For instance, in 22q deletion syndromes (digeorge syndrome) one of the common heart diseases is tetralogy of fallot and variants of tetralogy of fallot. ...Read more

What happens with ?Tetralogy of fallot?

What happens with ?Tetralogy of fallot?

Heart surgery: This is a congenital heart defect knows at "tetralogy" because the initial description discussed four findings: 1) ventricular septal defect, 2) overriding aorta, 3) pulmonary stenosis, 4) right ventricular hypertrophy. The cause is abnormal conotruncal septation, giving too much to the outflow to the aorta and not enough to the outflow to the lungs. This defect always requires surgical repair. ...Read more

What is meaning of a congenital heart defect in baby, especially the atrial septal defect?

What is meaning of a congenital heart defect in baby, especially the atrial septal defect?

Unfinished formation: The heart develops originally from a long tube that folds on itself in the embryo & forms the main chambers & features. The walls between the chambers are outgrowths that come together. If the walls did not completely form a gap will exist.In the upper chamber if a gap is left the atrial septal defect is "unfinished formation". ...Read more

Is getting a tetralogy of fallot hereditary?

Sometimes: Microdeletion of chromosome 22q11 (digeorge syndrome) is a genetic abnormality that has been linked to tof and other forms of congenital heart defects. It also can occur with down syndrome (trisomy 21), and in patients with no identified genetic abnormality. Heart defects occur in 0.8% of babies, but in 3-5% of those with 1st degree relatives with heart defects. There is a genetic predisposition. ...Read more

What is the pathophysiology of tetralogy of fallot?

Tetralogy of fallot: Is a congenital malformation. Uneven septation of the embryological troncus: small PA, larger Aorta with overriding the VSD , RV hypertrophy, presence of a VSD, Obstruction of the RV outflow, diminished blood flow to the lungs, usually requires an arterial shunt to the PA to increase blood flow in to the lungs, the surgery is done as neonatal. Total repair by the age of 4-5 years. ...Read more

Is tetralogy of fallot a hereditary problem?

Is tetralogy of fallot a hereditary problem?

Not typically.: Most cases are isolated and sporadic. It accounts for 5-10% of all congenital heart defects. 15% of tof cases are part of known genetic syndromes (down, digeorge, alagille, phenylketonuria) or associations (charge/vacterl) and some are linked to poorly controlled preconceptional maternal diabetes mellitus. Recurrence risk: 2.5% with one prior affected child, 8% with two. Folic acid may prevent it! ...Read more

What does aortic overriding mean with tetralogy of fallot?

What does aortic overriding mean with tetralogy of fallot?

Over a VSD: The aorta is normally attached to the left ventricle and carries oxygenated blood to the body. In tetralogy of fallot, the aorta arises over a ventricular septal defect (vsd, a hole between the left and right ventricles of the heart). This means that unoxygenated blood from the right ventricle also flows into the aorta. ...Read more

Tetralogy of fallot diagnosed in fetus? How accurate is scan?

Fairly accurate: In experienced centers, a fetal diagnosis of tetralogy of fallot should be reasonably accurate, although some of the specific anatomic details that may have an impact on the timing and type of surgical approach may not be readily apparent until after birth. ...Read more

Is a PDA (patent ductus arteriosus) considered a chd (congenital heart defect)..?

Yes: Yes - if it persists then it would qualify as chd and if it is audible in a child past infancy then it would ordinarily be closed in the cathetization laboratory. ...Read more

What is the survival rate for tetralogy of fallot?

Depends: Tetralogy of fallot is a complex type of congenital heart disease. Milder subtypes have a better long term survival than the more severe subtypes. Studies have demonstrated overall actuarial 10-, 20-, 30- and 36-year survival rates of 97%, 94%, 89% and 85%, respectively. ...Read more

Can malnutrition worsen 13 year olds congenital heart defect-tetralogy of Fallot, valve regurgitation, and various holes throughout the heart?

Can malnutrition worsen 13 year olds congenital heart defect-tetralogy of Fallot, valve regurgitation, and various holes throughout the heart?

Yes, because...: Malnutrition worsens everything related to a one's health, both mentally and physically. In the U.S., with it's economic wealth and ample food supply, there is little malnutrition, except for people who have very little variety in their diets, who refuse to eat, who cannot eat due to medical problems, or who cannot absorb nutrients from their food. Heart is muscle, and muscles need good nutrition. ...Read more

What are the causes fetal heart defects?

What are the causes fetal heart defects?

Multifactorial.: Genetic, metabolic, infectious and environmental causes can lead to cardiac birth defects. Taking Folic Acid 1-5 mg daily for your reproductive life (18-50) can prevent 75% of those defects. ...Read more
