  Coarctation of the aorta (CoA) is a congenital heart defect that affects the aorta, the main artery that carries blood from the heart to the body. It occurs when a part of the aorta is narrowed or constricted, which can cause decreased blood flow to the body and increased pressure in the heart. CoA can range from mild to severe and can be detected at birth or later in life. Causes of CoA According to Dr Ramji Mehrotra , who is one of the best cardiac surgeons in India, the exact cause of CoA is unknown, but it is thought to be caused by abnormal development of the aorta during foetal development. It can also be associated with other congenital heart defects or genetic disorders, such as Turner syndrome. Symptoms Symptoms of CoA can vary depending on the severity of the narrowing and the age at which it is detected. Infants with severe CoA may present with symptoms such as difficulty breathing, poor feeding, or a weak pulse in the legs. Older children and adults may experien

A stent is a tiny, expandable metal mesh tube that is used to prop open narrow or blocked arteries in the heart. Stents are commonly used in the treatment of coronary artery disease, a condition in which the arteries that supply blood to the heart become narrowed or blocked due to the build-up of plaque. When plaque builds up inside the arteries, it can restrict blood flow to the heart, leading to chest pain or other symptoms. In some cases, the blockage can be so severe that it can cause a heart attack. A stent can be used to help restore blood flow and prevent these complications. During a stenting procedure, a small incision is made in the groin or arm, and a thin, flexible tube called a catheter is inserted into the artery. The catheter is then guided to the blocked artery in the heart using imaging technology. Once the catheter reaches the blockage, a small balloon is inflated to widen the artery and improve blood flow. The stent is then placed over the balloon and expanded,
