Suspected Coarctation of the aorta
Suspected Trisomy 21
Narrowing of the aorta
Constricted segment of the
aorta that comprises localized
medial thickening.
5-8% of all congenital heart
defects
May also occur with bicuspid
aortic valve and VSD
(Cates, 2009)
Increased afterload on the left ventricle
Increased wall stress resulting in ventricular
hypertrophy
As the PDA closes (may cause rapid CHF and shock)
Causes increased left ventricular pressures, increased left
atrial pressure, and opening of the foramen ovale
Resulting in left-to-right shunting and dilation of the right
atrium and right ventricle
When the foramen ovale doesn’t open the pulmonary
venous and artery pressures increase
Resulting in right ventricular dilation
(Gholampour, et al., 2006)
Clinical findings
Systolic ejection murmur that radiates to the apex and is often loudest
in the back
Xray finidngs
Generalized cardiomegaly with normal pulmonary vascular density
(Pre-ductal Coarctation)
Enlarges left ventricle and left atrium and dilated ascending aorta
(Post-ductal Coarctation)
Pre-ductal and post-ductal SpO2 saturation discrepancy
Upper and lower extremity BP discrepancy
Absent or decreased lower extremity pulses
Tachypnea
Lethargy
Poor feeding
Shock
(Gomella, 2013)
Cyanotic lower extremities
(Syamasundar, 2012)
Medical Treatment
Prostaglandin E
0.05-0.15 mcg/kg/min
Ventilatory assistance
To support increased work of breathing
Inotropic drugs
Dopamine, Dobutamine, Epinepherine
Diuretics
Used for infants with CHF
Foley Catheter
Strict monitoring of urine output and renal perfusion
UAC
ABGs
(Cates, 2009)
Surgical Treatment
Goal is to bypass the narrowed section of the aorta
Left subclavian aortoplasty
Resection and end-to-end anastomosis
Angioplasty with Dacron patch
Stenting
Balloon angioplasty
(Gholampour, et al, 2004).
Down Syndrome
Presence of an extra 21st chromosome
Most common of all multiple congenital anomaly
(MCA) syndromes
Occurs in ~ 1 in 650 births
Neonatal mortality is related to severe cardiac
anomalies
Maternal nondisjunction
Occurring in the first meiotic division accounts for ~65% of cases
Occurring in the second meiotic division accounts for ~23% of
cases
(Blackburn, 2007)
(Gomella, 2013)
1st trimester screening
Ultrasound between 10 4/7 and 13 4/7 weeks gestation
Measurement of the nuchal translucency (increased in Trisomy 21)
Detects 70% of Trisomy 21
2nd trimester screening
Serum screening between 15 and 20 6/7 weeks gestation
Alpha fetoprotein (AFP), hCG, and unconjugated estriol (Triple
Screen)
Alpha fetoprotein (AFP), hCG, unconjugated estriol, and inhibin-A
(Quad screen) results in 80% detection
Decreased AFP, increased hCG, decreased PAPP-A, and increased
Inhibin A
(Bajaj & Gross, 2011)
Physical findings
Hypotonia, poor or absent moro reflex, flat
facial profile, protruding tongue, up slanting
palperbral fissures, Brushfield spots, anomalous
auricles, joint hyperextensibility, excess nuchal
skin, fifth-digit brachydactyly/clinodactyly, and
single transverse palmar crease.
Associated Anomalies
Congenital heart defects in 40% of infants (most
common ASD or VSD), PDA, endocardial cushion
defect, aberrant subclavian artery.
Hirschsprung disease, duodenal or esphageal
atresia, imperforate anus, hearing loss (66%),
mental deficiency, and renal and urinary tract
(Gomella, 2013)
anomalies.
(Jones, 2006)
Treatment
There is no cure for Down’s
syndrome
Supportive care
Early intervention is essential to assist
in the progression of developmental
milestones.

DOL 0 @ 1 hour of life ECHO obtained
Study limited by technical limitations. Atrial level shunt, quantitatively normal
biventricular size and systolic function. Ventricular level shunting cannot be
excluded. Greater than ½ systemic right ventricular systolic pressures. Tapering of
the transverse aorta without evidence of discrete narrowing or stenosis; coarctation
cannot be excluded in the presence of a ductus.

Cardiovascular continued
DOL 2 repeat ECHO
Small superior atrial level communication with left-to-right flow. Mild to moderate
right heart enlargement as well as right ventricular hypertrophy with normal right
ventricular systolic function. Structurally normal-appearing mitral valve with mild
mitral regurgitation. Normal left ventricular size and systolic function in the
presence of flattened interventricular septal wall motion. Moderate sized patent
ductus arteriosus with bidirectional flow. This is a left arch with a common
brachiocephalic trunk as the first arch vessel. The transverse aortic arch is diffusely
narrowed measuring approximately 3.5mmfor a Z-score of negative 2.5. There is
mildly turbulent color low through the transverse aortic arch and there is a peak
gradient of 8mmHg in the descending aorta. There does not appear to be a further
discrete narrowing of the aortic isthmus. However, cannot completely rule out
coarctation in the presence of a PDA. Normal left coronary artery origin. Right
coronary artery origin not well visualized. Systemic to supersystemic RV pressure by
septal position, TR jet, and PDA flow.

COARCTATION OF THE AORTA
Until surgery can be performed PGE is needed.
Surgical correction has the lowest risk of restenosis then any
other treatment.
Although surgical correction reduces the morbidity and
mortality rate. These infant’s still have a decreased life
expectancy related to poor blood pressure control.
Outcome is worse when there is also a hypoplastic arch present.
If the ECHO is performed by someone whom is not experienced
in neonates and small children a CT or cardiac MRI should be
performed to officially adequately assess the aortic arch.
Surgical intervention is the preferred method of treatment
because those whom have a balloon dilation will almost always
need a repeat dilation and/or surgery.
(Shah, 2014)
(Panzer & Dewolf, 2014)
TRISOMY 21
Currently there is no cure for Down’s syndrome.
Genetic studies are focuses on finding therapies to improve
learning and potential therapies.
Early intervention programs, physical therapy, occupational
therapy, and speech therapy can improve outcomes.
At greater risk for hearing, vision, and learning deficits.
Leukemia is more common with Trisomy 21 patients then those
without.
(Heyn & Perlstein, 2014)
Mother and father were concerned immediately
after birth, questions answered and plan of care
explained. Infant skin to skin with mother prior
to transfer to NICU for further evaluation.
Father accompanied infant to NICU and further
questions answered. After recovery mother
visited infant in the NICU, asked appropriate
questions regarding suspected Coarctation and
Trisomy 21.

Coarctation is a constricted segment of the aorta
that comprises localized medial thickening and
can be life threatening if not diagnosed and
treated.
A prenatal diagnosis of Coarctation of the aorta
can assist the medical professionals in the
preparation for treatment.
Trisomy 21 is a genetic defect that may have
multiple associated anomalies.
Confirmation of a prenatal diagnosis is important
to assist the family in the acceptance of a child
with a chronic disorder and/or a genetic
disorder.
Although it is common for a Trisomy 21 infant to
have an associated heat defect it is not
commonly associated with coarctation of the
aorta.
