Question
- In the adult form of Coarctation of the Aorta, the constriction is seen:a.Distal to ductus arteriosusb.Proximal to ductus arteriosusc.Lateral to ductus arteriosusd.Medial to ductus arteriosus
Solution
The correct answer is a. Distal to ductus arteriosus.
Coarctation of the Aorta (CoA) is a congenital heart defect where a part of the aorta is narrower than usual. If the narrowing is in the adult form, it is typically located distal to the ductus arteriosus. The ductus arteriosus is a blood vessel in a fetus that bypasses pulmonary circulation by connecting the pulmonary artery directly to the ascending aorta. After birth, this vessel is supposed to close off; if it doesn't, it can lead to health problems. In the case of CoA, the narrowing occurs after (or distal to) this vessel.
