Alert, awake
respiratory distress with alar flaring
– symmetrical chest expansion
– RR: 70 cpm (tachypneic);
– (+) subcostal retractions
– (+) crackles on both lung fields
• Ht: 49 cm ( z=-3 severely stunted; BMI: 19.58 ( z= above 2
overweight)
• (+) holosystolic murmur at the left parasternal area
• small defects: physical findings are primarily
cardiac manifestations
• moderate-to-large defects: growth may be affected
• Infants with small defects
– normal vital signs.
– Physiologic splitting of S2 is usually retained
– harsh, holosystolic murmur is loudest along the lower
left sternal border (LSB), and it is well localized.
• Small defects can produce a high-pitched or squeaky noise.
• Infants with moderate defects
– normal length and decreased weight
• Poor weight gain is a sensitive indicator of congestive heart
failure (CHF).
–

mild tachypnea, tachycardia, and an enlarged liver
The precordial activity is accentuated.
The murmur associated with thrill
A holosystolic harsh murmur is most prominent over the
lower LSB.
– The intensity of the pulmonary component is usually
normal or slightly increased.
– a diastolic rumble may be detected in the mitral area.
• This rumble suggests functional mitral stenosis secondary to a
large left-to-right shunt and indicates a surgical-level shunt
• Infants with large ventricular septal defects
– signs of CHF are present
• tachycardia, tachypnea, and hepatomegaly
• cardiomegaly
– The murmur is holosystolic but poorly
localized and is usually associated with a
diastolic rumble
ASD
• first heart sound may be normal or split
– best appreciated at the upper left sternal
border and may be transmitted to the lung
fields.
– second heart sound becomes widely split and
fixed
• fixed splitting of S2 is an important diagnostic
finding in atrial-level shunting
PDA
• history of premature birth, perinatal distress, or
perinatal hypoxia may be present
• If the left-to-right shunt is large, precordial activity
is increased
• The apical impulse is laterally displaced
• A thrill may be present in the suprasternal notch or
in the left infraclavicular region
• The first heart sound is typically normal. The
second heart sound (S2) is often obscured by the
murmur
• Continuous machinery murmur
AS
• may present as congestive heart failure in
the first week of life that mimic sepsis
• Often, neonates with aortic stenosis are
asymptomatic but present with a systolic
murmur
PS

Most are asymptomatic cardiac murmurs that are detected during routine examination.
moderate or severe pulmonary stenosis : exertional dyspnea.
severe or critical obstruction: signs of systemic venous congestion
Physical findings depend on the degree of obstruction.

healthy and are well developed.
trivial, mild, or moderate stenosis, and many with severe stenosis, are acyanotic
A thrill may be felt in the suprasternal notch and at the left upper sternal border (pulmonic area)
precordial thrill
first heart sound may be normal; second heart sound is widely split
A fourth heart sound may be heard at the left lower sternal border in patients with severe
obstruction
An ejection systolic click is heard along the left sternal border
An ejection systolic murmur of grade II-VI to V-VI is best heard at the left upper sternal border with
radiation into infraclavicular regions, axillae, or back.
Hepatosplenomegaly may develop in cases of CHF.
Peripheral pulmonary stenosis (commonly encountered in the neonate) is usually associated with a
grade II/VI systolic murmur that radiates into the posterior lung fields and axillae

Early presentation: poor feeding, tachypnea, and lethargy and progress to overt CHF and
shock.
Late presentation: Patients often present after the neonatal period with hypertension or a
murmur
Other presenting symptoms may include headaches, chest pain, fatigue, or even lifethreatening intracranial hemorrhage.
Many patients are asymptomatic except for the incidentally noted hypertension.
As with history, physical examination may conveniently separate patients into 2 groups:
those who present early with heart failure and those who present later with hypertension.
Early presentation
–
–
–
–
Neonates: tachypnea, tachycardia, and increased work of breathing and may even be moribund
with shock.
blood pressure discrepancies between the upper and lower extremities and reduced or absent
lower extremity pulses to palpation
In patients with low cardiac output and ventricular dysfunction, pulses may be diminished diffusely,
and BP gradients may seem minimal
The murmur associated with coarctation of the aorta may be nonspecific yet is usually a systolic
murmur in the left infraclavicular area and under the left scapula.

Clinical Impression

VENTRICULAR SEPTAL
DEFECT
Ventricular Septal Defect
• most common ACHD (25%)
• SYNONYMS
* Roger’s disease
* Interventricular septal defect
* Congenital cardiac anomaly
Ventricular Septal Defect
• Physical size of the VSD is a major determinant of the size of
the left-to-right shunt
• Restrictive VSD (usually <0.5 cm2) - right ventricular pressure
is normal
• Large nonrestrictive VSDs (usually >1.0 cm2)- right and left
ventricular pressure is equalized
Anatomical Classification
• Membranous/
perimembranousVSD
– Most common CHD
(males>females)
• • Muscular VSD
– “Swiss cheese” VSD
• Supracristal VSD
– Least common
ANCILLARY PROCEDURES
ECHOCARDIOGRAPHY
• Two-dimensional (2D) and Doppler colorflow mapping
• May be used to identify the type of defect
in the ventricular septum, size of the shunt
and the degree of pulmonary hypertension
ECHOCARDIOGRAPHY

Results
Small restrictive VSDs
Normal tracing
Medium-sized VSDs
Broad, notched P wave characteristic of
left atrial overload
• Signs of LV volume overload —
deep Q and tall R waves with tall T
waves in leads V5 and V6
• Signs of atrial fibrillation are often
present
Large VSDs
Right ventricular hypertrophy with rightaxis deviation.
With further progression, the ECG shows
biventricular hypertrophy; P waves may be
notched or peaked.

perihilar areas.
The heart is not enlarged.
Diaphragms are slightly flattened with intact
costophrenic sulci
Impression: Consider Pneumonia with mild
hyperaeration
TREATMENT
Initial medical treatment for infants
• Cardiac glycoside (digoxin 10-20mcg/kg per
day)
• Loop diuretics (furosemide 1–3 mg/kg per day)
• ACE inhibitors (captopril 0.5–2 mg/kg per day)
CARDIAC GLYCOSIDES
•
possess positive inotropic activity, which is mediated by
inhibition of sodium-potassium adenosine triphosphatase
(ATPase).
• also reduces conductivity in the heart, particularly
through the AV node; therefore, they have a negative
chronotropic effect
• used to slow the heart rate in supraventricular
arrhythmias, especially atrial fibrillation.
ACE INHIBITORS
• Used to treat CHF
• May be of use to treat systemic afterload
SURGICAL CLOSURE
• involved placing a restrictive band across the
main PA.
• proposed since pulmonary vascular disease as
a result of unimpeded flow to the lungs was
recognized as a dreaded complication of a
ventricular septal defect
• with low mortality and morbidity

Objectives
• To determine the effectiveness of a pulseoximetric screening performed on the first day of
life for the detection of congenital heart disease
in otherwise healthy newborns
• To determine if a pulse-oximetric screening
combined with clinical examination is superior in
the diagnosis of congenital heart disease to
clinical examination alone
Methods
• Study design: prospective multi-centre
study
• Zurich, Switzerland; May 2003 to May
2004
• Population: infants above 35 weeks of
gestation (n=3,262)

Conclusion
• Postductal pulse-oximetric screening in
the first few days of life is an effective
means for detecting cyanotic congenital
heart disease in otherwise healthy
newborns
