what is fallot's tetralogy??

Answer 1

It is actaully called Tetralogy of Fallot. It is a congenital heart disease and ALWAYS requires open-heart surgery. It is four "defects"
1. Pulmonary stenosis - narrowing of the pulmonary artery or it can be pulmonary valveular stenosis where the narrowing is on the valve.
2. A VSD - hole between the 2 bottom chambers of the heart, the ventricles
3. An overriding Aorta - displaced above the VSD instead of going to the left ventricle (where it is supposed to
4. Right Ventricular Hypertrophy - enlargement of the right ventricle due to the VSD and Pulmonary stenosis.

It is an EXTREMELY serious CHD, I know because my son has it. He was diagnosed at 8 days old and had his first open-heart surgery at 3 weeks old - a BT Shunt, which was done to allow more blood flow to his lungs until he was big enough to have his "full repair" which he had done at 9 months old. They patched the VSD and removed his pulmonary valve - ( he had valveular stenosis). He is now 16 months old and is doing great! His Right Ventricual hypertrophy is getting pretty bad though because of the constant regurgitation from his pulmonary artery from not having a valve. if you want to know anymore about it please e-mail me =)

Answer 2

Fallot's tetralogy

Also known as:
Fallot’s syndrome
Fallot’s tetrad
Steno-Fallot tetralogy

Associated persons:
Etienne-Louis Arthur Fallot
Niels Stensen

Description:
A congenital condition characterized by:

1. Stenosis of the pulmonal artery.
2. Defect in the interventricular septum.
3. Dextroposition of the aorta.
4. Hypertrophy of the right ventricle.

It forms about 10 % of congenital heart disease. Both sexes affected; slight male prevalence. Detected weeks or months after birth. Clinical features are cyanosis from birth or developing in the first year of life caused by the lung's inability to oxygenate sufficient blood for the system, difficulty in feeding, failure to gain weight, retarded growth and physical development, dyspnoea on exertion, clubbing of the fingers and toes, and polycythaemia. Many cases can be operated successfully. There may be permanent cyanosis. Also found in cattle and dog.

Some writers prefer the term «Fallot’s syndrome», saying that that the term «Fallot’s tetralogy» is a misnomer inasmuch as hypertrophy of the right ventricle, which comprises the fourth characteristic of the tetralogy, is simply the functional consequence of the triad of congenital malformations.

The Blalock-Taussig operation corrects this condition surgically.

The deformation of the heart known as the tetralogy of Fallot was first described in 1671 by the Danish physician, natural scientist, bishop – and later Saint –Niels Stensen (Nicolaus Stenonius). At least some forty case descriptions precluded that of Fallot. His delineation from 1888 was based on details of the pathological features of two persons with the condition, together with a survey of some 50 previous observations.

Fallot considered the deformity as an entity and as such the most common cause of cardiac cyanosis. By his contemporaries Fallot's observations were considered to be solely of theoretical or curious interest. Congenital heart malformations attracted little attention, as there was still no therapy available. Fallot's work first received serious attention when Paul Dudley White (1886-1973) in 1931 discussed the malformation and translated Fallot's works.

Answer 3

Tetralogy of Fallot is a combination of 4 heart defects at birth. They are:
1. Ventricular Septal Defect (Hole between the ventricles (pumping chambers) of the heart)
2. Rt. Ventricular Hypertrophy (Small, undeveloped rt ventricle)
3. Pulmonary Stenosis (Narrowing at or below the valve between the rt ventricle and the pulmonary artery)
4. Overriding Aorta (Aorta covers the outflow of both the right and left ventricles)

PDA (Patent Ductus Arterosis) or Atrial Septal Defect may or may not be present, but is not considered part of Tetralogy of Fallot. With most congenital heart defects, there is rarely only one syndrome present.

Answer 4

Its basically a heart defect and the common cause for Blue Baby Syndrome and is the most common cyanotic heart defect Fallots is made up of four malfunctions.
A hole between the two bottom ventricles (chambers) of the heart
Right ventricle outflow blockage
The heart valve is not solely connected to the left ventricle but instead can be attached to the right or even the left and right.
The right ventricle is more advanced and powerful than the others. other effect can be:
stenosis of the left pulmonary artery, in 40% of patients
a bicuspid pulmonary valve, in 40% of patients
right-sided aortic arch, in 25% of patients
coronary artery anomalies, in 10% of patients
an atrial septal defect, in which case the syndrome is sometimes called a pentalogy of Fallot
an atrioventricular septal defect
partially or totally anomalous pulmonary venous return
forked ribs and scoliosis

I know its sounds complicated but its our heart!! here's a link that may help a bit.

Answer 5

Actually, the condition is called Tetrology of Fallot. It is a heart defect that affects the chambers of the heart and also the ventricles. Sometimes the arteries can be narrow, making the heart work harder than it should. The other part of the defect is that there is an opening or hole between the chambers. This is serious because it allows the oxygenated blood and the deoxygenated blood to "flow" between the two chambers. It causes fatigue and malaise.
Tetrology of Fallot is categorized in two ways: Pink or Blue Tets. A Pink tet is more desirable because it means that the heart condition is not depriving your body of so much oxygen that you suffocate. This is what my son was before he had heart surgery. A blue tet is when your skin turns blue from lack of oxygen. Hope this helps.

Answer 6

Briefly answering :

Fallot's tetralogy - a congenital heart defect producing cyanosis; characterized by four symptoms: pulmonary stenosis and ventricular septal defect and malposition of the aorta over both ventricles and hypertrophy of the right ventricle.

Answer 7

Wow, I wish you would e-mail me I know alot about it. I was born with tet and at 8 moths. had open heart surgery. I am now fine but i do have a long scar and three little holes on my chest. Honestly, the doctors told my mom it was rare and not hereditary. I have always been afraid if i had kids they would have the same problem, but I have been assured by a few doctors, the chance of me being a tet baby and having a tet baby are highly unlikely, they said the chances would be astronomical. If he really worries, ask your doctor. Anyway, good luck to the two of you and I hope everything works out. Your husband will be in my prayers, if you have anymore questions, go a head e-mail me. Anything I don't know about tet- I'm know my mom does, she studied it for a very long time while she was worried about me.

Answer 8

1.Patent ductus arteriosis, 2, Septal defect, 3, overriding aorta, 4. Stenosis of pulmonary artery. The patent ductus is an integral part of the syndrome left out by the first answerer.
