Tetralogy of Fallot ( TOF) is a that is present at birth. Symptoms include episodes of. When affected babies cry or have a, they may develop a 'tet spell' where they turn very blue, have difficulty breathing, become limp, and occasionally. Other symptoms may include a, and easy tiring upon. The cause is typically not known. Risk factors include a mother who uses, has, is over the age of 40, or gets during pregnancy.
It may also be associated with. Classically there are four defects:. a, a hole between the two., narrowing of the exit from the right ventricle., enlargement of the right ventricle.
an, which allows blood from both ventricles to enter the TOF is typically treated by in the first year of life. Timing of surgery depends on the baby's symptoms and size. The procedure involves increasing the size of the and and repairing the ventricular septal defect. In babies who are too small a temporary surgery may be done with plans for a second surgery when the baby is bigger. Most people who are affected live to be adults.
Long-term problems may include an and. TOF occurs in about 1 in 2,000 newborns. Males and females are affected equally. It is the most common complex congenital heart defect. It was initially described in 1671.
A further description was published in 1888 by the French physician, after whom it is named. The first surgical repair was carried out in 1954. With nail beds in an adult with tetralogy of Fallot Tetralogy of Fallot results in low of blood due to the mixing of oxygenated and deoxygenated blood in the left ventricle via the (VSD) and preferential flow of the mixed blood from both ventricles through the aorta because of the obstruction to flow through the pulmonary valve. This is known as a.
The primary symptom is low blood oxygen saturation with or without from birth or developing in the first year of life. If the baby is not cyanotic then it is sometimes referred to as a 'pink tet'. Other symptoms include a which may range from almost imperceptible to very loud, difficulty in feeding, failure to gain weight, retarded growth and physical development, dyspnea on exertion, clubbing of the fingers and toes, and. The baby may turn blue with breast feeding or crying. Tet spells Children with tetralogy of Fallot may develop 'tet spells'. These are acute hypoxia spells, characterized by shortness of breath, cyanosis, agitation, and loss of consciousness. This may be initiated by any event leading to decreased oxygen saturation or that causes decreased systemic vascular resistance, which in turn leads to increased shunting through the ventricular septal defect.
Tet spells are characterized by a sudden, marked increase in cyanosis followed by, and may result in hypoxic brain injury and death. Older children will often during a tet spell. This increases and allows for a temporary reversal of the.
It increases pressure on the left side of the heart, decreasing the right to left shunt thus decreasing the amount of deoxygenated blood entering the systemic circulation. Cause Its cause is thought to be due to environmental or genetic factors or a combination. It is associated with chromosome 22 deletions and. Specific genetic associations include:. studies show that it is a result of anterior malalignment of the, resulting in the clinical combination of a VSD, pulmonary stenosis, and an overriding aorta.
Right ventricular hypertrophy develops progressively from resistance to blood flow through the right ventricular outflow tract. Pathophysiology Four malformations ' denotes four parts, here implying the syndrome's four. This is not to be confused with the similarly named, a field of medicine concerned with abnormal development and congenital malformations (including tetralogy of Fallot).
Below are the four malformations that present together in tetralogy of Fallot. Normal heart Condition Description A narrowing of the right ventricular outflow tract. It can occur at the (valvular stenosis) or just below the (infundibular stenosis). Infundibular pulmonic stenosis is mostly caused by overgrowth of the heart muscle wall (hypertrophy of the septoparietal trabeculae), however the events leading to the formation of the overriding aorta are also believed to be a cause. The pulmonic stenosis is the major cause of the malformations, with the other associated malformations acting as compensatory mechanisms to the pulmonic stenosis.
The degree of stenosis varies between individuals with TOF, and is the primary determinant of symptoms and severity. This malformation is infrequently described as sub-pulmonary stenosis or subpulmonary obstruction. An with biventricular connection, that is, it is situated above the ventricular septal defect and connected to both the right and the left ventricle. The degree to which the aorta is attached to the right ventricle is referred to as its degree of 'override.' The aortic root can be displaced toward the front (anteriorly) or directly above the septal defect, but it is always abnormally located to the right of the root of the pulmonary artery.
The degree of override is extremely variable, with 5-95% of the valve being connected to the right ventricle. (VSD) A hole between the two bottom chambers (ventricles) of the heart.
The defect is centered around the most superior aspect of the ventricular septum (the outlet septum), and in the majority of cases is single and large. In some cases thickening of the septum (septal hypertrophy) can narrow the margins of the defect. The is more muscular than normal, causing a characteristic boot-shaped (coeur-en-sabot) appearance as seen by chest X-ray. Due to the misarrangement of the external ventricular septum, the right ventricular wall increases in size to deal with the increased obstruction to the right outflow tract. This feature is now generally agreed to be a secondary anomaly, as the level of hypertrophy tends to increase with age. There is anatomic variation between the hearts of individuals with tetralogy of Fallot. Primarily, the degree of right ventricular outflow tract obstruction varies between patients and generally determines clinical symptoms and disease progression.
Presumably, this arises from an unequal growth of the. The aorta is too large, thus 'overriding,' and this 'steals' from the pulmonary artery, which is therefore stenosed. This then prevents ventricular wall closure, therefore VSD, and this increases the pressures on the right side, and so the R ventricle becomes bigger to handle the work. Additional anomalies In addition, tetralogy of Fallot may present with other anatomical anomalies, including:. stenosis of the, in 40%. a, in 60%., in 25%.
anomalies, in 10%. a patent or, in which case the syndrome is sometimes called a pentalogy of Fallot. an.
partially or totally. forked ribs and Tetralogy of Fallot with ( pseudotruncus arteriosus) is a severe variant in which there is complete obstruction (atresia) of the right ventricular outflow tract, causing an absence of the pulmonary trunk during embryonic development. In these individuals, blood shunts completely from the right ventricle to the left where it is pumped only through the aorta. The lungs are perfused via extensive collaterals from the systemic arteries, and sometimes also via the ductus arteriosus.
Diagnosis. A CXR (Chest X-Ray) of a child with tetralogy of Fallot Congenital heart defects are now diagnosed with, which is quick, involves no radiation, is very specific, and can be done prenatally. Before more sophisticated techniques became available, chest x-ray was the definitive method of diagnosis.
The abnormal ' (boot-like) appearance of a heart with tetralogy of Fallot is classically visible via chest x-ray, although most infants with tetralogy may not show this finding. Absence of interstitial lung markings secondary to pulmonary oligaemia are another classic finding in tetralogyas is the sign. Treatment Tet spells Tet spells may be treated with such as, but acute episodes require rapid intervention with or intranasal to reduce ventilatory drive, a vasopressor such as, or to increase systemic vascular resistance, and IV fluids for volume expansion.

Oxygen (100%) may be effective in treating spells because it is a potent pulmonary vasodilator and systemic vasoconstrictor. This allows more blood flow to the lungs by decreasing shunting of deoxygenated blood from the right to left ventricle through the VSD. There are also simple procedures such as and the knee chest position which increase systemic vascular resistance and decrease right-to-left shunting of deoxygenated blood into the systemic circulation. Palliative surgery The condition was initially thought untreatable until surgeon, cardiologist, and lab assistant at Johns Hopkins University developed a palliative surgical procedure, which involved forming a side to end between the and the. This first surgery was depicted in the film. It was actually Helen Taussig who convinced Alfred Blalock that the shunt was going to work.
This redirected a large portion of the partially oxygenated blood leaving the heart for the body into the lungs, increasing flow through the pulmonary circuit, and greatly relieving symptoms in patients. The first surgery was performed on 15-month-old on November 29, 1944 with dramatic results. The Potts shunt and the Waterston-Cooley shunt are other shunt procedures which were developed for the same purpose. These are no longer used. Currently, Blalock-Thomas-Taussig shunts are not normally performed on infants with TOF except for severe variants such as TOF with (pseudotruncus arteriosus). Total surgical repair The Blalock-Thomas-Taussig procedure, initially the only surgical treatment available for tetralogy of Fallot, was palliative but not curative.
The first total repair of tetralogy of Fallot was done by a team led by at the in 1954 on an 11-year-old boy. Total repair on infants has had success from 1981, with research indicating that it has a comparatively low mortality rate. Total repair of tetralogy of Fallot initially carried a high mortality risk, but this risk has gone down steadily over the years. Surgery is now often carried out in infants one year of age or younger with less than 5% perioperative mortality. The open-heart surgery is designed to relieve the right ventricular outflow tract stenosis by careful of muscle and to repair the VSD with a patch or a. Additional reparative or reconstructive surgery may be done on patients as required by their particular cardiac anatomy.
Epidemiology Tetralogy of Fallot occurs approximately 400 times per million live births and accounts for 7 to 10% of all congenital heart abnormalities. Prognosis Untreated, tetralogy of Fallot rapidly results in progressive right ventricular hypertrophy due to the increased resistance caused by narrowing of the pulmonary trunk.
This progresses to heart failure which begins in the right ventricle and often leads to left heart failure and dilated cardiomyopathy. Mortality rate depends on the severity of the tetralogy of Fallot. If left untreated, TOF carries a 35% mortality rate in the first year of life, and a 50% mortality rate in the first three years of life.
Untreated TOF also causes delayed growth and development, including delayed puberty. Patients who have undergone total surgical repair of tetralogy of Fallot have improved hemodynamics and often have good to excellent cardiac function after the operation with some to no exercise intolerance (New York Heart Association Class I-II). Surgical success and long-term outcome greatly depend on the particular anatomy of the patient and the surgeon's skill and experience with this type of repair. Ninety percent of people with total repair as babies develop a progressively leaky pulmonary valve later in life. It is recommended that they follow up at a specialized adult congenital heart disease center.
