A grade of patent without stenosis was given to any vessel displaying no or only minor disturbances in color-flow characteristics and no stenoses of ≥50%. A grade of patent with stenosis was assigned to any vessel displaying moderate or severe disturbances in color-flow characteristics and a stenosis of ≥50%.
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 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.
The definition of “patent” coronary arteries is “having no narrowing of the left main, left anterior descending, left circumflex, or right coronary arteries or their main branches.”.
A large PDA causes irregular blood flow in the heart and lungs. As a result, pressure rises in the pulmonary artery. Over time, the increased pressure damages the smaller blood vessels in the lungs. A life-threatening and permanent type of lung damage called Eisenmenger syndrome may occur.
Abstract. Patent ductus arteriosus (PDA) is a rare diagnosis in adults, since symptoms and signs usually occur in infancy and most cases are treated shortly after diagnosis.
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.
The ductus arteriosus should close on its own within a few days after birth. When the opening does not close, this connection between arteries is considered a patent, or open, ductus arteriosus. Small connections may not cause problems, but larger connections can cause a range of symptoms and require closure.
There are five requirements that must be met to obtain a patent: patentable subject matter, utility, novelty, nonobviousness and enablement. This post will provide a general overview of this topic, but as always, this post is for educational purposes only and does not contain legal advice.
The five primary requirements for patentability are: (1) patentable subject matter; (2) utility; (3) novelty; (4) non-obviousness; and (5) enablement. Like trademarks, patents are territorial, meaning they are enforceable in a specific geographic area.
