Introduction
Patent foramen ovale in newborns generally refers to a condition where the foramen ovale—the opening between the left and right atria of the heart—fails to close. Normally, after birth, as the pressure in the left atrium increases, the foramen ovale closes during this period. When a newborn presents with patent foramen ovale, it typically means that the opening between the left and right atria of the heart has not closed properly.
Patent foramen ovale (PFO) in newborns generally refers to a condition where the foramen ovale—the opening between the left and right atria of the heart—fails to close properly. The specific analysis is as follows:
After birth, as pressure in the left atrium increases, the foramen ovale normally closes during this period. If a newborn has a patent foramen ovale, it means that the opening between the left and right atria remains unclosed. However, in most cases, this condition resolves spontaneously within one year after birth. If the opening persists beyond the age of three years, a diagnosis of patent foramen ovale can be considered. This may lead to reduced cardiac function and symptoms such as arrhythmia and chest pain. In such cases, prompt medical attention at a qualified healthcare facility is recommended, and treatment may involve a surgical procedure to permanently close the open foramen ovale.
It is advised that if any discomfort or abnormal symptoms are observed in a newborn, timely medical evaluation should be sought. Appropriate treatment based on individual circumstances should be initiated promptly to avoid delaying the condition and potentially affecting subsequent growth and development.
