# Patent Foramen Ovale in Children: A Review of Epidemiological Characteristics, Natural Course, and Intervention Strategies

## TL;DR

Patent foramen ovale is common in children, especially in preterm infants and those with genetic syndromes, and often requires delayed or no intervention unless complications arise.

## Contribution

This paper reviews recent research on PFO in children, focusing on epidemiology, natural course, and intervention strategies to guide clinical decisions.

## Key findings

- PFO is highly prevalent in preterm infants and children with specific genetic syndromes.
- Most asymptomatic children with PFO do not require immediate intervention.
- Individualized risk stratification is essential for determining the need for intervention.

## Abstract

What are the main findings?
The incidence of patent foramen ovale in children is relatively high, particularly in preterm infants and children with specific genetic syndromes.Delayed intervention is recommended to avoid unnecessary procedural risks for asymptomatic children with patent foramen ovale.

The incidence of patent foramen ovale in children is relatively high, particularly in preterm infants and children with specific genetic syndromes.

Delayed intervention is recommended to avoid unnecessary procedural risks for asymptomatic children with patent foramen ovale.

What is the implication of the main finding?
The high incidence yet benign nature of patent foramen ovale requires increased awareness and screening to identify high-risk cases needing intervention.Intervention strategies require individualized risk stratification, favoring monitoring for most but intervening for complications like stroke.

Patent foramen ovale (PFO) is a common cardiac structural abnormality in children, which has garnered significant clinical attention due to its epidemiological characteristics and natural course. Although PFO is asymptomatic in many cases, its potential complications and impact on children’s health should not be underestimated. In recent years, there has been an increase in research on the epidemiological data of PFO in children under 16 years old. However, controversy remains regarding its natural course and clinical intervention strategies. This paper reviews the latest research progress on PFO in terms of epidemiological characteristics, natural course, current interventions, indications, timing of percutaneous PFO closure, risks, and complications, aiming to provide evidence-based guidance for clinical decision-making and improved management strategies for children with patent foramen ovale.
