Patent Foramen Ovale in Fetal Life, Infancy and Childhood

Area of Science:

• Pediatric Cardiology
• Congenital Heart Disease
• Echocardiography

Background:

• Patent foramen ovale (PFO) is a frequent echocardiographic finding in healthy children.
• The association between PFO and various childhood clinical conditions remains controversial.
• Conditions linked to PFO include cryptogenic stroke, platypnea-orthodeoxia syndrome, decompression sickness, and migraine.

Purpose of the Study:

• To review the embryology and anatomy of PFO in relation to postnatal development.
• To discuss diagnostic modalities for PFO in specific clinical contexts.
• To examine the role of PFO in pediatric congenital heart disease and critical care settings.

Main Methods:

• Literature review focusing on PFO embryology, anatomy, and clinical associations.
• Analysis of diagnostic techniques for PFO in children.
• Examination of PFO's role in complex pediatric cardiac conditions and life support.

Main Results:

• PFO is a common finding with debated clinical significance in pediatric populations.
• Contradictory data exists regarding PFO's role in stroke, platypnea-orthodeoxia, and other syndromes.
• PFO's involvement in congenital heart disease and its impact on children requiring mechanical support is explored.

Conclusions:

• The clinical relevance of PFO in asymptomatic children requires further investigation.
• Diagnostic strategies and management should be tailored to individual clinical circumstances.
• Understanding PFO's role is crucial for pediatric patients with complex cardiac conditions and those on life support.
