Patent ductus arteriosus (PDA) is a persistent opening between two major blood vessels leading from the heart. The opening, called the ductus arteriosus, is a normal part of a baby’s circulatory system before birth that usually closes shortly after birth. If it remains open, however, it’s called a patent ductus arteriosus. A small patent ductus arteriosus often doesn’t cause problems and might never need treatment. However, a large patent ductus arteriosus left untreated can allow poorly oxygenated blood to flow in the wrong direction, weakening the heart muscle and causing heart failure and other complications. Treatment options include monitoring, medications and closure by cardiac catheterization or surgery.
What is patent ductus arteriosus? The ductus arteriosus is a blood vessel that attaches the aorta to the pulmonary artery during fetal development, and usually closes after birth. If it stays open, however, it’s known as patent ductus arteriosus. Subscribe – https://goo.gl/w5aaaV. More videos – https://goo.gl/UhOKiM. Support us on Patreon – https://goo.gl/ZGHEk4.
