A patent foramen ovale (PFO) is a hole in the heart that didn't close the way it should after birth. The hole is a small flaplike opening between the upper heart chambers. The upper chambers of the heart are called the atria.
PFO itself usually does not cause any symptoms. PFO can occasionally result in complications. The most serious of these is stroke. Most people will not need treatment for a PFO.
The word "patent" means open. The ductus arteriosus is a blood vessel that allows blood to go around the baby's lungs before birth. Soon after the infant is born and the lungs fill with air, the ductus arteriosus is no longer needed.
Procedures to close a patent foramen ovale include: Device closure. In this procedure, the provider inserts a thin, flexible tube called a catheter into a blood vessel in the groin area. The catheter tip has a device to plug the PFO . Surgical closure. In this heart surgery, the surgeon uses stitches to close the PFO .
A small patent ductus arteriosus often doesn't cause problems and might never need treatment. However, a large, untreated patent ductus arteriosus can let oxygen-poor blood move the wrong way. This can weaken the heart muscle, causing heart failure and other complications.
Patent ductus arteriosus, or PDA, is a heart defect that can develop soon after birth. It affects the way blood flows through a baby's lungs. Mild PDA might not need treatment, but some children with the defect may require catheterization or surgery.
2) The foramen magnum is the opening in the bottom of the skull through which the spinal cord exits. "Widely patent" means that is is of normal size. 3) This term means there is a bit of extra bone growth around the openings in the spinal column through which the nerve roots from the spinal cord emerge.
Patent foramen ovale (PFO) is a hole between the left and right atria (upper chambers) of the heart. This hole exists in everyone before birth, but most often closes shortly after being born. PFO is what the hole is called when it fails to close naturally after a baby is born.
