What is Pentalogy Of Cantrell

Pentalogy of Cantrell is a rare, life-threatening congenital disorder characterized by a specific combination of five structural defects involving the chest and abdomen. Because Pentalogy of Cantrell severely affects the development of the heart, diaphragm, and abdominal wall, it typically requires complex, multi-stage surgical intervention shortly after birth.

What are the five core features of Pentalogy of Cantrell?

The diagnosis of Pentalogy of Cantrell is based on the presence of five classic developmental abnormalities. While not every patient presents with all five, the condition is defined by the following:

• Ectopia cordis: The heart is positioned partially or entirely outside the thoracic cavity.


• Omphalocele: A defect in the abdominal wall that allows abdominal organs to protrude into the base of the umbilical cord.


• Diaphragmatic defects: A hole or lack of development in the diaphragm.


• Pericardial defects: A defect in the membrane (pericardium) that surrounds the heart.


• Sternal defects: A cleft or absence of the lower portion of the breastbone (sternum).

How rare is Pentalogy of Cantrell and who is affected?

Pentalogy of Cantrell is an extremely rare condition with an estimated incidence of approximately 1 in 65,000 to 1 in 200,000 live births. It is a sporadic condition, meaning it typically occurs randomly without a family history. There is no known geographic predilection, and while some literature suggests a slight male predominance, it affects infants of all backgrounds.

What causes Pentalogy of Cantrell?

The exact cause of Pentalogy of Cantrell remains largely unknown, though it is believed to result from a failure of the lateral plate mesoderm (the tissue that forms the chest and abdominal walls) to develop correctly during the first few weeks of embryonic life. Because Pentalogy of Cantrell involves such complex structural malformations, it is often identified via prenatal ultrasound.

How does this condition differ from other abdominal wall defects?

Unlike isolated omphalocele or gastroschisis, Pentalogy of Cantrell is distinguished by the specific involvement of the heart and the chest wall. The presence of ectopia cordis is the hallmark feature that differentiates Pentalogy of Cantrell from other congenital ventral wall defects.

Next steps

• Consult with a pediatric cardiothoracic surgeon and a neonatologist at a tertiary care center.


• Connect with the DiseaseMaps.org community to share experiences with other families navigating rare congenital heart and abdominal conditions.


• Request a referral to a clinical geneticist to rule out associated chromosomal anomalies.
