Coarctation Of The Aorta Research Paper

Improved Essays
Coarctation of the Aorta Coarctation of the aorta is a congenital defect that can occur in infants. A congenital defect is present at birth and may or may not be discovered before delivery. Once discovered, management of the condition and treatment must begin immediately.
Etiology
Coarctation of the aorta presents as a narrowing of the aorta near the heart. Specifically, near where the ductus arteriosus joins the heart. Because this narrowing occurs distal to the vessels that supply blood to the head and upper extremities, those locations receive higher blood pressure. The areas that are supplied with blood from the aorta distal to this area receive less blood and have lower blood pressure. These areas include the abdomen and lower extremities. It is thought a variety of factors including environment and genetics converge in utero and cause this defect. (Hockenberry & Wilson, 2015)
Pathophysiology
The result of this congenital defect is increased arterial pressure proximal to the obstruction at the vessels that supply the head, neck, and upper extremities, and lower arterial pressure distal to the obstruction to the abdominal aorta and its branches. Coarctation of the aorta makes up 5–9% of all congenital conditions of the heart. ( Kaya, Deniz, Paydas, & Aksun, 2012)

Digoxin may be used in cases of heart failure, so the nurse will need to monitor for signs of digoxin toxicity, including vomiting, diarrhea, dysrhythmias, decreased urine output, and reduced level of consciousness. After surgical repair of the defect, the nurse will need to assess for hypertension and administer medications such as nitroprusside, esmolol, or milrinone, and ACE inhibitors or beta-blockers to reduce the workload of the heart.

    Another anatomical abnormality is patent ductus arteriosus—this condition is when two major arteries, the aorta and pulmonary, are connected and have abnormal blood flow and usually happens following birth. Before birth, the aorta and pulmonary arteries are connected by the ductus arteriosus for fetal blood circulation. However, immediately after birth up to a few days, the duct closes on its own as part of the normal development process. However, the duct doesn’t always close, which leads to the patent ductus arteriosus condition. It puts a strain on the heart and increases blood pressure in the pulmonary system.…

    (CNN)Mia Gonzalez spent the first 3½ years of her life missing out. She had to skip day care and dance classes because she constantly had colds and pneumonia. When Mia could go out and play, she was easily winded and took multiple asthma medications to try to help her breathing. After about 10 hospital stays, doctors realized that Mia had a malformation in her aorta, the vessel that pumps blood from the heart. The 4-year-old would need an operation to close off the part of her aorta that was putting pressure on her windpipe and making it hard to breathe, swallow and get rid of phlegm when she got a cold.…

    Atrial septal defects(ASD) is a highly prevalent congenital heart disease [1]. There are four major types of ASD: Ostium Secundum, ostium premium, sinus venous, and coronary sinus [2]. The ostium atrial septal defect is an abnormally large opening in the atrial septum. During the early embryo stages, the atria enlarge, and the septum primum develops with the progression of the embryo.…

    One year after I visited with Lady and the Leverings, I returned. I found that Lady had somewhat recovered from her surgery and still had vet visits due to the surgery complications. During Lady’s surgery Aronson cut in Lady’s aorta like a T-joint in a pipe. For the next ten minutes, she sutured the joint together. Then, just as she was putting in the final stitch, her needle caught the back wall of the artery.…

    Transposition of the Great Vessels Transposition of the great vessels is a heart condition that is present in infants at birth and often known as a congenital heart defect or the more common term is the transposition of the great arteries(TGA). TGA is when the two main arteries, the pulmonary artery and the aorta, are switched in position, or "transposed". As a normal heart, deoxygenated blood returning to the heart from the body is pumped from the right side of the heart through the pulmonary artery to the lungs and to the left side of the heart then back out to the rest of the body with oxygenated blood and the cycle repeats. In TGA, deoxygenated blood returning are not going to the lungs to be oxygenated, but is pumped back out to the body.…

    Atrial septal defect (ASD) is an abnormal communication between the atria (McCance, Huether, Brashers, & Rote, 2010, p. 1219). It is considered as the fourth most common congenital heart defect, comprising about 5% to 10% of all congenital cardiac defects. The causes of ASD remains unknown, but it was thought that genetics play a role. A person with no other heart defect, or a small defect (less than 5 millimeters) may remain asymptomatic, or manifest symptoms later in life ("MedlinePlus," 2014).…

    Discovered in 1913 by a man named Nikolai Anichkov, atherosclerosis is a disease where things like calcium and fat build up in the arteries and block blood flow. Arteries harden as a result of it, and it’ll cause problems transferring blood around the body. The plaque will form a barrier, and can cause serious problems in the body, like other diseases and disorders. The results are possibly deadly. There is a layer on the inside of every vein that keeps it smooth called endothelium.…

Every year about 1 million Americans die due to cardiovascular related problems, which is about 42% of total death per year. Cardiovascular disease is the disease of heart and vascular system of the human body that includes narrowing down or blocking of blood vessels (arteries, veins and capillaries) that can lead to range of diseases such as coronary artery disease, arrhythmia, congenital heart defects, angina (chest pain) and stroke. Even though cardiovascular disease is common only in adult population, it is very likely that each age group including children and adolescents have the disease risk factors. Most common…
