Tetralogy of Fallot is a congenital heart defect characterized by four abnormalities: pulmonary stenosis, ventricular septal defect, overriding aorta, and right ventricular hypertrophy. It results in inadequate blood flow to the lungs, causing cyanosis. Clinical features include cyanosis, clubbing of fingers and toes, and episodes where cyanosis worsens called "Fallot's spells." Diagnosis is made through echocardiogram, EKG, chest x-ray and cardiac catheterization. Treatment involves palliative shunt surgery in infants and total surgical correction later in childhood, with the goal of separating the pulmonary and systemic circulations and allowing adequate blood flow to the lungs. Prognosis after total correction is generally good,
A cyanotic heart defect is a group-type of congenital heart defects (CHDs). The patient appears blue (cyanotic), due to deoxygenated blood bypassing the lungs and entering the systemic circulation. This can be caused by right-to-left or bidirectional shunting, or malposition of the great arteries.
Cyanotic heart defects, which account for approximately 25% of all CHDs, include:
Tetralogy of Fallot (ToF)
Total anomalous pulmonary venous connection
Hypoplastic left heart syndrome (HLHS)
Transposition of the great arteries (d-TGA)
Truncus arteriosus (Persistent)
Tricuspid atresia
Interrupted aortic arch
Pulmonary atresia (PA)
Pulmonary stenosis (critical)
Eisenmenger syndrome(Reversal of Shunt due to Pulmonary Hypertension) .
Patent ductus arteriosus may cause cyanosis in late stage.

commonly used for medical students, and helpful to use this ppt to study for them, and also a common man can understand very easily what is coarctation of aorta.
Some babies with tricuspid atresia have other conditions, such as pulmonary stenosis or transposition of the great arteries, that also affect blood flow through their heart. These conditions require treatment, too.
A congenital heart defect is a problem with the structure of the heart. It is present at birth. Congenital heart defects are the most common type of birth defect. The defects can involve the walls of the heart, the valves of the heart, and the arteries and veins near the heart. They can disrupt the normal flow of blood through the heart. The blood flow can slow down, go in the wrong direction or to the wrong place, or be blocked completely.
Doctors use a physical exam and special heart tests to diagnose congenital heart defects. They often find severe defects during pregnancy or soon after birth. Signs and symptoms of severe defects in newborns include
Rapid breathing
Cyanosis - a bluish tint to the skin, lips, and fingernails
Fatigue
Poor blood circulation
Many congenital heart defects cause few or no signs and symptoms. They are often not diagnosed until children are older.
Many children with congenital heart defects don't need treatment, but others do. Treatment can include medicines, catheter procedures, surgery, and heart transplants. The treatment depends on the type of the defect, how severe it is, and a child's age, size, and general health.

Patent ductus arteriosus (PDA) is a congenital disorder in the heart wherein a neonate's ductus arteriosus fails to close after birth. Early symptoms are uncommon, but in the first year of life include increased work of breathing and poor weight gain. With age, the PDA may lead to congestive heart failure if left uncorrected. The ductus arteriosus is a normal fetal blood vessel that closes soon after birth. In a patent ductus arteriosus (PDA) the vessel does not close and remains "patent" (open) resulting in irregular transmission of blood between two of the most important arteries close to the heart, the aorta and the pulmonary artery. PDA is common in neonates with persistent respiratory problems such as hypoxia, and has a high occurrence in premature children. In hypoxic newborns, too little oxygen reaches the lungs to produce sufficient levels of bradykinin and subsequent closing of the DA. Premature children are more likely to be hypoxic and thus have PDA because of their underdeveloped heart and lungs.
A patent ductus arteriosus allows a portion of the oxygenated blood from the left heart to flow back to the lungs by flowing from the aorta (which has higher pressure) to the pulmonary artery. If this shunt is substantial, the neonate becomes short of breath: the additional fluid returning to the lungs increases lung pressure to the point that the neonate has greater difficulty inflating the lungs. This uses more calories than normal and often interferes with feeding in infancy. This condition, as a constellation of findings, is called congestive heart failure.
In some cases, such as in transposition of the great vessels (the pulmonary artery and the aorta), a PDA may need to remain open. In this cardiovascular condition, the PDA is the only way that oxygenated blood can mix with deoxygenated blood. In these cases, prostaglandins are used to keep the patent ductus arteriosus open

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.
Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

2. Introduction
▪ Tetralogy of Fallot (TOF) is one of the most common congenital
heart disorders (CHDs).
▪ This condition is classified as a cyanotic heart disorder, because
tetralogy of Fallot results in an inadequate flow of blood to the
lungs for oxygenation (right-to-left shunt)
▪ Patients with tetralogy of Fallot initially present with cyanosis
shortly after birth, thereby attracting early medical attention.
▪ Louis Arthur Fallot, after whom the name tetralogy of Fallot is
derived
5. Haemodynamics
▪ Acyanotic Fallot :
- Obstruction to pulmonary flow is minimal
- Pink Fallot
▪ Cyanotic Fallot :
- Pulmonary resistance is high
- Increased shunting right-to-left side aggravating the central cyanosis
6. Aetiology
▪ The embryological causes is abnormal development of bulbar septum
that separates the ascending aorta from the pulmonary artery
▪ It normally aligns and fuses with the outflow part of intraventricular
septum
▪ Prenatal factors associated with a higher incidence of tetralogy of Fallot
(TOF) include maternal rubella (or other viral illnesses) during pregnancy,
poor prenatal nutrition, maternal alcohol use, maternal age older than 40
years, maternal phenylketonuria (PKU) birth defects, and diabetes.
Children with Down syndrome also have a higher incidence of tetralogy of
Fallot, as do infants with fetal hydantoin syndrome or fetal
carbamazepine syndrome.
▪ The defect occurs in about 1 in 2000 births
7. Clinical features
▪ Most infants with tetralogy of Fallot have difficulty with feeding,
and failure to thrive (FTT) is commonly observed
▪ At birth, some infants with tetralogy of Fallot do not show signs of
cyanosis, but they may later develop episodes of bluish pale skin
during crying or feeding and may become apnoeic and
unconscious – Fallot’s spells
▪ In older children, Fallot’s spells are uncommon but cyanosis
becomes increasingly apparent, stunting of growth, digital
clubbing ,polycythemia, chest pain ,headache and tachyponea
▪ Some children characteristically obtain relief by squatting after
exertion, which increases the afterload of left heart and reduces
the right-to-left shunt - Fallot’s sign
8. ▪ On examination :
▪ Combination of cyanosis with a loud ejection systolic murmur in
the pulmonary area
▪ However, cyanosis may be absent in the newborn or in patients
with only mild right ventricular flow obstruction
9. Differential diagnosis
▪ TGA with pulmonary stenosis
▪ VSD with pulmonary stenosis
▪ TGA with VSD with pulmonary stenosis
▪ VSD with pulmonary atresia
▪ Tricuspid atresia
▪ Eisenmenger’s syndrome
17. ▪ Total correction
• Brock’s procedure : The infundibulum is resected and patch
closure of VSD is done.
• Rastelli’s operation : In cases with severe hypoplasia or atresia of
right ventricular outflow
usually done after 5 yrs . Pulmonary artery is divided from
left ventricle and cardiac end is overseen. An intracardiac tunnel is
placed between large VSD and aorta.
The right ventricle is connected to divided pulmonary artery
by an aortic homograft.
19. ▪ The prognosis after total correction is good, especially if the operation
performed in childhood
▪ Follow up is needed to identify residual shunting, recurrent pulmonary
stenosis and arrhythmias
▪ An implantable defibrillator is sometimes recommended in adulthood
