A BSTRACT
Ectopia cordis is a rare congenital condition. It is defned as the abnormal position of the heart outside the thoracic cavity, associated with
defects in the parietal pericardium, diaphragm, sternum, and, in most cases, cardiac malformations. Ectopia cordis was frst proposed by Abott
in 1998, although cases of patients with similar defects have been reported in the past. Ectopia cordis is produced by segmental defects in
the mesodermal development in the third week of intrauterine life, and/or amniotic band syndrome that causes simultaneous cerebral and
thoracoabdominal malformations. The existence of ectopia cordis with severe congenital heart disease may be confrmed in the prenatal
period by vaginal echocardiography at 10–12 weeks of gestation or by abdominal echocardiography at 20–22 weeks. For such defects surgical
correction is the only hope of survival, although the overall success rate is very poor. In recent years, surgery has been attempted in one or
two phases with variable results that depend mainly on the type of associated heart disease. A 37 years old woman with gestational age of
29.5 weeks was referred for third trimester ultrasound to detect fetal anomaly. The fetal heart was seen outside lower the chest wall which was
later confrmed by elective cesarean section. The heart was not covered with a membrane (pericardium). The rest of the anterior abdominal
wall was intact. The abdomen was distended due to ascites.

I NTRODUCTION
Ectopia cordis is a condition in which there is partial or complete
displacement of the heart outside of the thoracic cavity. It can
occur either as a solitary malformation or can be associated with
other abnormalities that afect the abdomen, thorax, or both.
1
It
is categorized into four types based on the location of the heart:
cervical, in which the heart is located higher into the area of
neck (3% of cases); thoracic, in which the heart bulges anteriorly
through a sternal defect (60% of cases); thoracoabdominal, in
which the heart is located outside of the chest (7% of cases);
and abdominal, in which the heart is located inferiorly into the
abdomen (30% of cases).
2
The etiology of ectopic cordis has not
been fully elaborated; however, there are various theories about
this.
3
The estimated prevalence of Ectopia cordis is 5.5–7.9 per
million live births and its frequency is 0.1% among all congenital
heart diseases.
4,5
With the help of ultrasonography, early detection
of fetal anomalies is becoming more common. Ectopic cordis
diagnosed by ultrasound through the frst trimester scan ofers
options of termination at earlier gestational ages which can reduce
the psychological and physical trauma on some patients.
6
The
prenatal sonographic evaluation of ectopia cordis is comparatively
easy with two-dimensional real-time ultrasonography and it
depends on the presentation of a pulsating heart outside the chest
of the fetus. The prenatal diagnosis in the frst trimester has been
recorded; however, the diagnosis before 9 weeks of gestation
has not been documented.
7
The ultrasound performed within
the frst trimester or by the start of the second trimester allows
sufcient time to elaborate associated abnormalities. However,
sometimes the diagnosis through ultrasonography can be difcult
especially in the minor form of ectopia cordis, in such cases, it
is superior to use three-dimensional scanning to demonstrate
fetal bones because of greater contrast diference as compared
to contiguous organs.

C ASE P RESENTATION
A 37 years old G5P5A0 (Gravida5, para5, abortion0) woman
with a gestational age of 29.5 weeks was referred for the third
trimester ultrasound scan because the fundal height was greater
than dates (LMP), to detect multiple pregnancy or fetal anomaly.
The antenatal ultrasound scan showed a single, live, intrauterine
gestation corresponding to a gestational age of 29 weeks and
5 days, on ultrasound scan, the fetal heart was visualized outside
the chest wall through a defect in the lower sternum in association
with anterior diaphragmatic and ventral abdominal wall defects
suggestive of thoracoabdominal variety of complete ectopia
cordis. There was a breach in the normal outline of the lower
sternum indicating a sternal defciency. The fetal pericardium was
absent, free fuid was present in the abdominal cavity therefor
abdominal circumference (AC) measurement was considered
unreliable. The placenta was anterior and normal with the normal
amniotic fluid. Clubfeet and hands were present. The patient
