Introduction

• The most common heart disease in children

are congenital heart disease and rheumatic

fever with its consequences.

• Congestive cardiac failure is a common

pediatric emergency, with its different

etiology than that of adults. 2R Dh@ker, Lecturer, PCNMS

• Congenital heart defects are problems with

the heart's structure that are present at birth.

These defects can involve:-

• The interior walls of the heart

• The valves inside the heart

• The arteries and veins that carry blood to

the heart or the body

R Dh@ker, Lecturer, PCNMS 3

• There are many types of congenital heart

defects. They range from simple defects with

no symptoms to complex defects with severe,

life-threatening symptoms.

• They affect 8 out of every 1,000 newborns

R Dh@ker, Lecturer, PCNMS 4

Cont…introduction

• Other heart disease which may found in

infants and children are cardiomyopathy,

myocarditis, pericardial disease etc.

Congenital Heart disease

• CHD is the structural malformation of the heart

or grater vessels, present at birth.

• It is the most common congenital malformation

• The exact number of prevalence is not known

13R Dh@ker, Lecturer, PCNMS

Etiology • The exact cause of CHD is unknown in about 90%

of case.

• Heredity and consanguineous marriage are

important etiology factors.

• Genetic disorder and chromosomal aberrations (

trisomy – 21, Turner's syndrome) are also known

to predispose congenital heart disease. 14R Dh@ker, Lecturer, PCNMS

Cont…

• Other associated factors responsible for CHD

include fetal and maternal infections, drug intake,

alcohol intake by mother, maternal IDDM, fetal

hypoxia, birth asphyxia etc.

15R Dh@ker, Lecturer, PCNMS

Classification of CHD

• CHD can be grouped into three categories-

• Acynotic CHD- there is increased pulmonary

blood flow due to left to right shunt. It includes:-

– Ventricular septal defect (VSD)

– Atrial septal defect (ASD)

– Patent ductus arteriosus (PDA)

– Atrio- Ventricular canal (AVC)

16R Dh@ker, Lecturer, PCNMS

Cont…Classification of CHD

• Cyanotic CHD- there is diminished pulmonary

blood flow due to Right to Left shunt. It

includes:-

– Tetralogy of fallot (TOF)

– Tricuspid Atresia (TA)

– Transposition of grater arteries (TGA)

– Hypoplastic left heart syndrome

17R Dh@ker, Lecturer, PCNMS

Cont…

• Obstructive lesions:-

–Coarctation of aorta

–Aortic Value stenosis

–Pulmonary value stenosis

–Congenital mitral stenosis

18R Dh@ker, Lecturer, PCNMS

R Dh@ker, Lecturer, PCNMS19

Ventricular septal Defect (VSD)

20R Dh@ker, Lecturer, PCNMS

• A ventricular septal defect is an opening in the

ventricular septum, or dividing wall between the

two lower chambers of the heart known as the

right and left ventricles.

• VSD is a congenital (present at birth) heart defect.

• As the fetus is growing, something occurs to affect

heart development during the first 8 weeks of

pregnancy, resulting in a VSD21R Dh@ker, Lecturer, PCNMS

• It is most common acyanotic congenital

heart disease.

• It is found approximately 25% of all CHD.

• The size of defect can be small & large.

22R Dh@ker, Lecturer, PCNMS

R Dh@ker, Lecturer, PCNMS 23

Etiology

• In most children, the cause isn't known

• In some cases, the tendency to develop a VSD may

have a genetic basis.

• Risk factors

– Ventricular septal defect appears to run in families

and sometimes occurs with other genetic problems,

such as Down syndrome

24R Dh@ker, Lecturer, PCNMS

Cont….etiology

• Having the following conditions during pregnancy

can increase risk of having a baby with a heart

defect.

–Rubella infection

– Poorly controlled diabetes

–Drug or alcohol use or exposure to certain

substances

25R Dh@ker, Lecturer, PCNMS

Types of VSD

• Membranous VSD

• Muscular VSD

• Atrioventricular canal type VSD

• Conal septal VSD

26R Dh@ker, Lecturer, PCNMS

Symptoms of VSD

• The size of the ventricular septal opening will

affect the type of symptoms noted, the severity of

symptoms, and the age at which they first occur.

• The following are the most common symptoms of

VSD.

– fatigue

– sweating

– rapid breathing

– heavy breathing

27R Dh@ker, Lecturer, PCNMS

Cont…Symptoms of VSD

– congested breathing

–disinterest in feeding, or tiring while feeding

–poor weight gain

28R Dh@ker, Lecturer, PCNMS

Diagnosis • complete exam and look for signs of VSD, which

may include heart murmurs.

• Tests may perform include:

• chest x-ray

• electrocardiogram (ECG)

• echocardiogram (echo)

• cardiac catheterization

• cardiac magnetic resonance

imaging (MRI)29R Dh@ker, Lecturer, PCNMS

R Dh@ker, Lecturer, PCNMS 30

Treatment for ventricular septal

Defect

31

Specific treatment for VSD will be determined by child's

physician based on:

•Child's age, overall health, and medical history extent of

the disease

•Child's tolerance for specific medications, procedures, or

therapies

•Expectations for the course of the disease

•Opinion or preference

R Dh@ker, Lecturer, PCNMS

Cont…

• Medical management

• adequate nutrition

• infection control

• surgical repair

• interventional cardiac catheterization

• Postoperative care

32R Dh@ker, Lecturer, PCNMS

Medical management• In small VSD usually no medical management is

required.

• Surgical repairer may be indicated in some cases.

• Prevention of complication is very essential

measure.

• Spontaneous closure of VSD occurs in 30 to 50%

cases with small defect.33R Dh@ker, Lecturer, PCNMS

Cont…

• In large VSD, initial management of associated

problem like CCF and endocarditis, should be

done with appropriate treatment.

• Surgical is done as one- stage or two-stage

operational.

• One stage operational with patch closure of VSD

by Open-heart method can be performed.

34R Dh@ker, Lecturer, PCNMS

Cont…

• Two stage approach is done with first stage, to

band the pulmonary artery to restrict pulmonary

blood flow by closed- heart methods.

• Second stage operation is done to patch close the

VSD and remove the PA band.

35R Dh@ker, Lecturer, PCNMS

Complication

• The common complication of VSD are CCF,

recurrent respiratory tract infection, infective

endocarditis, pulmonary stenosis, pulmonary

hypertension.

36R Dh@ker, Lecturer, PCNMS

R Dh@ker, Lecturer, PCNMS 37

Patent Ducts

Arteriosus

R Dh@ker, Lecturer, PCNMS 38

R Dh@ker, Lecturer, PCNMS 39

Patent Ducts Arteriosus

• It is persistent vascular connection between the

pulmonary artery and the aorta.

• Functionally the closure of ductus arteriosus occurs

soon after birth.

• When ductus arteriosus remains patent and open after

birth, the blood flow in the ductus from the aorta to

the pulmonary artery due to higher pressure in the

aorta.

40R Dh@ker, Lecturer, PCNMS

• PDA is common in preterm infants who weight

less than 1.5kg.

• It is the more common type in female baby and

occurs approximately 11% of all CHDs.

• A small PDA may cause no symptoms, but a large

one may cause poor eating, failure to thrive or

breathlessness.

41R Dh@ker, Lecturer, PCNMS

• During the first 60 hours of life, spontaneous

closure of the ductus occurs in 55% of full-term

newborn infants.

• By 2-6 months of age, closure occurs in more

than 95% of healthy infants.

R Dh@ker, Lecturer, PCNMS 42

Type

R Dh@ker, Lecturer, PCNMS 43

Clinical manifestations• Clinical presentation of PDA depend upon the size

of ductus and its patency.

• Symptomatic cases manifested with –

– Tachycardia

– Bounding pulse

– Dyspnea and frequency respiratory infection.

– Precordial pain,

– hoarseness voice

– Feeding difficulties

– Slow weight gain

– Growth failure 44R Dh@ker, Lecturer, PCNMS

Diagnosis evaluation • History of illness

• Chest X-ray

• ECG

• Two- dimensional echocardiogram

• Doppler study

45R Dh@ker, Lecturer, PCNMS

R Dh@ker, Lecturer, PCNMS 46

Management

• Surgical Management

47R Dh@ker, Lecturer, PCNMS

Medical Management

• In symptomatic patient with PDA,

– Indomethanic 0.1 to 0.25mg/kg/IV over 30 minutes

very slowly is administered every 12 to 24 hrs for 3

doses.

– Anti-prostaglandin agent

– Aspirin

• Supportive care is provided with rest, adequate

intake of calorie for weight gain and promotion of

growth and development.

48R Dh@ker, Lecturer, PCNMS

Surgical management

• Transaction or ligation of patent ductus arteriosus

is performed via lateral thoracotomy, a closed

heart intervention.

• It is done preferably between 3 and 10 years of age

in asymptomatic patients and in symptomatic

patients.

• The result of surgery is excellent.

• pre- operative and post- operative care for

thoracic surgery to be provided with all

precaution.49R Dh@ker, Lecturer, PCNMS

Complication • CCF

• Infective endocarditis

• Pulmonary hypertension

• Rarely

– Thromboembolism

R Dh@ker, Lecturer, PCNMS 51

R Dh@ker, Lecturer, PCNMS 52

Atrial Septal Defect

R Dh@ker, Lecturer, PCNMS 53

Introduction

• A "hole" in the wall that separates the top two

chambers of the heart.

• This defect allows oxygen-rich blood to leak into

the oxygen-poor blood chambers in the heart.

• ASD is a defect in the septum between the heart's

two upper chambers (atria). The septum is a wall

that separates the heart's left and right sides.

R Dh@ker, Lecturer, PCNMS 54

R Dh@ker, Lecturer, PCNMS55

• Atrial Septal defects occur in 6 percent to 8

percent of all children born with congenital heart

disease.

• For unknown reasons, girls have Atrial Septal

defects twice as often as boys.

R Dh@ker, Lecturer, PCNMS 56

Etiology

• The causes of heart defects such as atrial septal defect

among most babies are unknown.

• Some babies have heart defects because of changes in their

genes or chromosomes.

• Very small defects of (less than 5 millimeters or ¼ inch) are

less likely to cause problems. Smaller defects are often

discovered much later in life than larger ones.

R Dh@ker, Lecturer, PCNMS 57

• Risk factors- during pregnancy may increase risk

of having a baby with a heart defect, including:-

– Rubella infection

– Drug, tobacco or alcohol use, or exposure to certain

substances

– Diabetes

– Obesity

– Phenylketonuria (PKU)

R Dh@ker, Lecturer, PCNMS 58

Epidemiology

• The 3 major types of atrial septal defect (ASD)

account for 10% of all congenital heart disease

and as much as 20-40% of congenital heart

disease presenting in adulthood.

• The most common types of ASD include the

following:-

R Dh@ker, Lecturer, PCNMS 59

Cont… Epidemiology

– Ostium secundum: The most common type of ASD

accounting for 75% of all ASD cases, representing

approximately 7% of all congenital cardiac defects and 30-

40% of all congenital heart disease in patients older than 40

years.

– Ostium primum: The second most common type of ASD

accounts for 15-20% of all ASDs.

– Sinus venosus: The least common of the three, sinus

venosus (SV) ASD is seen in 5-10% of all ASDs.

R Dh@ker, Lecturer, PCNMS 60

Type

• Ostium secundum atrial septal defect

• Ostium primum atrial septal defect

• Sinus venosus atrial septal defect.

• Coronary sinus atrial septal defect.

R Dh@ker, Lecturer, PCNMS 61

R Dh@ker, Lecturer, PCNMS 62

Clinical Manifestation

• Many babies born with atrial septal defects don't

have associated signs or symptoms.

• The size of an ASD and its location in the heart

will determine what kinds of symptoms a child

experiences.

R Dh@ker, Lecturer, PCNMS 65

Cont… clinical Manifestation

• Shortness of breath, especially when exercising

• Fatigue

• Swelling of legs, feet or abdomen

• Heart palpitations or skipped beats

• Frequent lung infections

• Stroke

• Heart murmur

R Dh@ker, Lecturer, PCNMS 66

Diagnostic Evaluation

• History of illness

• physical examination

• Chest X-ray

• Electrocardiogram (ECG)

• Echocardiogram (or “echo”)

• Cardiac catheterization

R Dh@ker, Lecturer, PCNMS 67

Management • A physician decides the best course of treatment

for ASD based on:

– A child's age, overall health and medical history

– Severity of the disease

– A child's tolerance for specific medications, procedures

or therapies

– Expectations for the course of the disease

– Parents’ opinions or preferences

R Dh@ker, Lecturer, PCNMS 68

Medical Management

• Many children have no symptoms and require no

medications.

• Digoxin

• Diuretics

R Dh@ker, Lecturer, PCNMS 69

Surgical Management

• A health care provider may recommend surgery

for a child with a large atrial septal defect, even if

there are few symptoms, to prevent problems

later in life.

• Surgery may also be recommended for an adult

who has many or severe symptoms.

R Dh@ker, Lecturer, PCNMS 70

• Surgery involves fixing the hole and may be done

through cardiac catheterization or open-heart

surgery.

• Repair of the defect is done by suture closure or

pericardial patch repair by suture closure or

pericardial patch repair by Open Hearth Surgery.

R Dh@ker, Lecturer, PCNMS 71

R Dh@ker, Lecturer, PCNMS 72

Complication

• Right-sided heart failure

• Heart rhythm abnormalities (arrhythmias)

• Increased risk of a stroke

• Infective endocarditis

• Less common serious

– Pulmonary hypertension

R Dh@ker, Lecturer, PCNMS 73

R Dh@ker, Lecturer, PCNMS 74

R Dh@ker, Lecturer, PCNMS 75

Tetralogy

of

fallot

76R Dh@ker, Lecturer, PCNMS

77R Dh@ker, Lecturer, PCNMS

• Tetralogy of Fallot (TOF) is a congenital heart

defect which is classically understood to involve

four anatomical abnormalities of the heart

• It is the most common cyanotic heart defect, and

the most common cause of blue baby syndrome.

• TOF is usually a right-to-left shunt, in which

higher resistance to right ventricular outflow

results in more severe cyanosis symptoms.78R Dh@ker, Lecturer, PCNMS

• This condition is characterized by the combinations

of four defect.

– Pulmonary stenosis

– Ventricular defect

– Overriding of aorta

– Right ventricular hypertrophy

• Tetralogy of Fallot is a rare, complex heart defect

that occurs in about 5 out of every 10,000 babies.

• It affects boys and girls equally.79R Dh@ker, Lecturer, PCNMS

• Ventricular septal defect (VSD)

• Overriding aorta − the aortic valve is enlarged and appears to

arise from both the left and right ventricles instead of the left

ventricle as in normal hearts.

• Pulmonary stenosis − narrowing of the pulmonary valve and

outflow tract or area below the valve that creates an obstruction

(blockage) of blood flow from the right ventricle to the

pulmonary artery.

• Right ventricular hypertrophy − thickening of the muscular

walls of the right ventricle, which occurs because the right

ventricle is pumping at high pressure.

R Dh@ker, Lecturer, PCNMS 80

R Dh@ker, Lecturer, PCNMS 81

Causes Tetralogy of Fallot• Cause unknown

• Certain conditions or factors that occur during pregnancy may raise risk for having a child with tetralogy of Fallot. These conditions and factors include:

– German measles (rubella) and some other viral illnesses

– Poor nutrition

– Overuse of alcohol

– Age (being older than 40)

– Diabetes

• Heredity may play a role in causing tetralogy of Fallot.

82R Dh@ker, Lecturer, PCNMS

Clinical manifestation • Clinical feature of TOF depend upon size of VSD

and degree of right ventricular outflow

obstruction.

• Blue baby or cyanosis of lips and nailbeds with

Dyspnea is found initially with crying and

exertion in neonates especially when the ductus

arteriosus beings to close.

83R Dh@ker, Lecturer, PCNMS

• Hypercyanotic spells

• Irritability

• Dyspnea

• Cyanosis

• Tet spell

Transposition

of

Grater Arteries

95R Dh@ker, Lecturer, PCNMS

96R Dh@ker, Lecturer, PCNMS

• Transposition of the great arteries (TGA) is a heart

condition that is present at birth, and often is called

a congenital heart defect.

• TGA occurs when the two main arteries going out

of the heart—the pulmonary artery and the

aorta—are switched in position, or “transposed”.

• It accounting 5 to 10% of all CHDs.

• It occurs predominantly in males. 97R Dh@ker, Lecturer, PCNMS

Causes• The cause of TGA is unknown at this time.

• Scientific researchers have found that some diseases and behaviors might be associated with a higher risk for TGA. These include:-

– The mother having a viral illness during pregnancy

– The mother having poor nutrition during pregnancy

– The mother using an excessive amount of alcohol during pregnancy

– The mother being older than 40 years of age

– The mother having diabetes during pregnancy

– The baby having Down syndrome99R Dh@ker, Lecturer, PCNMS

Clinical Manifestation • Neonate with TGA is presented-

– Severe cyanosis

– Dyspnea

– Metabolic acidosis

Arterial switch procedure:

106R Dh@ker, Lecturer, PCNMS

Complications:

• Congestive heart failure

• Arrhythmia

• Eisenmenger syndrome (irreversible and

progressive pulmonary vascular obstructive

disease)

107R Dh@ker, Lecturer, PCNMS

Prognosis:• The overall survival rate following arterial switch

operation is 90%.

• The overall mortality rate following an atrial level

switch is low; however, long-term morbidity

associated with systemic (right) ventricular dilatation

and failure, systemic atrioventricular (tricuspid) valve

regurgitation, and atrial bradyarrhythmias and

tachyarrhythmias is significant.

108R Dh@ker, Lecturer, PCNMS

Congestive

Cardiac

Failure

110R Dh@ker, Lecturer, PCNMS

• Congestive cardiac failure (CCF) is a common

pediatric emergency.

• It is also termed as congestive heart failure.

• It indicates inadequate cardiac output.

• Heart failure (HF) results from structural or

functional cardiac disorders that impair the ability

of the ventricle(s) to fill with and/or eject blood.

111R Dh@ker, Lecturer, PCNMS

• Heart Failure (HF) is the clinical condition in

which the heart fails to meet the metabolic and

circulatory demands of the body.

• It presents as the final common pathway of a

combination of structural, functional and biologic

mechanisms.

• Pulmonary and/or systemic congestion may

develop as a consequence of heart failure,

resulting in Congestive Heart Failure (CHF)

R Dh@ker, Lecturer, PCNMS 112

Definition

• CCF can be defined as “inability of the heart to

maintain an output at rest or during stress,

necessary for the metabolic needs of the body and

inability to receive blood into the ventricular

cavities at low pressure during diastole”.

113R Dh@ker, Lecturer, PCNMS

Causes • Various forms of congenital heart disease such as

ventricular septal defect (VSD), patent ductus arteriosus (PDA) or common AV canal

• Heart valve disease caused by Rheumatic fever or other infections

• Infections of the heart valves and/or heart muscle (endocarditis)

• Cardiac arrhythmias (irregular heartbeats)

• Cardiomyopathy or another primary disease of the heart muscle

• Coronary artery disease

• Inflammation of heart muscle (myocarditis)

114R Dh@ker, Lecturer, PCNMS

Clinical Manifestation• Decrease cardiac output leads to inadequate supply of

oxygen and nutrition to the tissue.

• Failure to gain weight in infancy.

• Shortness of breath or labored breathing

• Fatigue

• Needing to take frequent rest breaks while playing with friends

• Falling asleep when feeding or becoming too tired to eat during infancy

• Cough and congestion in the lungs

• Sweating 115R Dh@ker, Lecturer, PCNMS

• Weak peripheral pulse

• Cool extremities

• Pallor

• Pulmonary congestion is manifested-

– Auscultation of heart sound. Rhythm

– Auscultation of lungs

• Chest X-ray

• CBC

• ECG

• ECHO

• Cardiac catheterization (cath)117R Dh@ker, Lecturer, PCNMS

Management • Management of CCF is aimed at correction of

inadequate cardiac output.

• This can be achieved by reducing cardiac work,

improving cardiac performance by reducing heart

size and correction the cause of heart failure.

118R Dh@ker, Lecturer, PCNMS

Cont…

• Sedative should be administered to managed

restlessness and to reduce anxiety.

• Diuretics – 0.5-1.5mg/kg.

• Digoxin

• Iron supplement

• Antibiotic

• Vasodilator

• ACE inhibitors

119R Dh@ker, Lecturer, PCNMS

Cont…

• Diet should be planned with low salt for sodium restriction and to given in small amount frequently.

• Supportive nursing care should be emphasize-

– Skin care

– Other hygiene measures

– Prevention of infection

– Fluid electrolyte balance

– Diet

– Administration of medication

– Continuous monitoring of child’s condition

– Maintenance of intake output and other record.

120R Dh@ker, Lecturer, PCNMS

Cont…

• Emotional support and health education with

necessary instruction should dietary and activity

restriction, drug intake, prevention of

complication, daily hygiene care and measures of

prevention of infection.

R Dh@ker, Lecturer, PCNMS 121

Prognosis • Prognosis in case of CCF depends upon the cause

and available of treatment.

• Early diagnosis and treatment promote better

prognosis.

• Long term suffering may lead to failure to thrive

and growth retardation.

R Dh@ker, Lecturer, PCNMS 122

Acute Rheumatic Fever

R Dh@ker, Lecturer, PCNMS 123

Introduction• Acute rheumatic fever is an autoimmune

collagen disease occurs as a hypersensitivity

reaction to group-A beta hemolytic

streptococcal infection.

• It is characterized by inflammatory lesion of

connective tissue and endothelial tissue.

R Dh@ker, Lecturer, PCNMS 124

• It affect-– Heart – Joint – Blood vessels – Other connective tissue. – Brian

• It is the most important acquired heart disease in

children and commonly found in 4 to 15 yr of age

with incidence rate 5.0/1000approximately.

• Rheumatic fever (RF), also known as acute

rheumatic fever (ARF)

R Dh@ker, Lecturer, PCNMS 125

Etiology • Predisposing factors of ARF are-

– genetic predisposition,

– temperate climate,

– winter season,

– unhygienic living condition,

– overcrowding in the family,

– poor dietary intake and

– increasing immunological response.

R Dh@ker, Lecturer, PCNMS 126

IN INDIA

• RHD is prevalent in range of 5-7/1000 in 5-15 age groups.

• About 1 million cases of RHD

• RHD constitutes 20-30% hospital admissions due to CVD.

• Streptococcal infections common in children living in under –privileged conditions and RF accounts for 1-

3% of the cases.

• Important cause of chronic disease and death in

developing world

• Underdiagnosed and undertreated

• Ages 5-15 yrs are most susceptible

• Rare <3 yrs

• Common in 3rd world countries

• Environmental factors-- over crowding, poor

sanitation, poverty, poor housing

• Incidence more during fall ,winter & early spring
