Coarctation of the aorta (CoA) [1] [2] is a congenital condition whereby the aorta is narrow, usually in the area where the ductus arteriosus (ligamentum arteriosum after regression) inserts. The word coarctation means "pressing or drawing together; narrowing". Coarctations are most common in the aortic arch. The arch may be small in babies ...
Coarctation’s a fancy way of saying “narrowing”, so a coarctation of the aorta means a narrowing of the aorta. If we look at the heart, we’ve got the right and left atria, the right and left ventricles, the pulmonary artery leaving the right ventricle to the lungs, and the aorta leaving the left ventricle and going to to the body.
Persistent truncus arteriosus (PTA), [1] often referred to simply as truncus arteriosus, [2] is a rare form of congenital heart disease that presents at birth. In this condition, the embryological structure known as the truncus arteriosus fails to properly divide into the pulmonary trunk and aorta.
In a sense it is the complete form of a coarctation of the aorta. Almost all patients also have other cardiac anomalies, including a ventricular septal defect (VSD), aorto-pulmonary window, and truncus arteriosus. There are three types of interrupted aortic arch, with type B being the most common.
An aortic coarctation is a narrowing of the aorta, which is split into infant and adult forms. In the infant form, it's often accompanied by patent ductus arteriosus, and mixing of deoxygenated and oxygenated blood, whereas in the adult form, the ductus arteriosus has closed off.
Total surgical repair of TOF is a curative surgery. Different techniques can be used in performing TOF repair. One method to permit pulmonary blood flow post-birth is the stenting of the ductus arterious (DA) through the inducement of a systemic-to-pulmonary shunt. This surgical approach has an 83% success rate.
An occupational hazard is a hazard experienced in the workplace. This encompasses many types of hazards, including chemical hazards, biological hazards (biohazards), psychosocial hazards, and physical hazards.
The term coarctation is another synonym, [5] but is commonly used only in the context of aortic coarctation. [ 6 ] [ 7 ] Restenosis is the recurrence of stenosis after a procedure.
