Transposition of the Great Arteries TGAnutchnoindexnutchnoindex. What is transposition of the great arteries Click Image to Enlarge. Transposition of the great arteries is a congenital present at birth heart defect. Due to abnormal development of the fetal heart during the first 8 weeks of pregnancy, the large vessels that carry blood from the heart to the lungs, and to the body are improperly connected. Essentially, the connections in the heart are swapped. Normally, oxygen poor blue blood returns to the right atrium from the body, travels to the right ventricle, then is pumped through the pulmonary artery into the lungs where it receives oxygen. Oxygen rich red blood returns to the left atrium from the lungs, passes into the left ventricle, and then is pumped through the aorta out to the body. Rapid heart rate can cause sudden cardiac arrest but is treatable. When atrial fibrillations irregular heart rate is not controlled, it can lead to stroke and heart.

Two separate circuits are formed one that circulates oxygen poor blue blood from the body back to the body, and another that recirculates oxygen rich red blood from the lungs back to the lungs. Other heart defects are often associated with TGA, and they actually may be necessary for an infant with transposition of the great arteries to live. An opening in the atrial or ventricular septum will allow blood from one side to mix with blood from another, creating purple blood with an oxygen level somewhere in between that of the oxygen poor blue and the oxygen rich red blood. Patent ductus arteriosus another type of congenital heart defect will also allow mixing of oxygen poor blue and oxygen rich red blood through the connection between the aorta and pulmonary artery. The purple blood that results from this mixing is beneficial, providing at least some oxygen to the body, if not a normal amount of oxygen. Because of the low amount of oxygen provided to the body, TGA is one of the heart problems called blue baby syndrome. Transposition of the great arteries is the second most common congenital heart defect that causes problems in early infancy. TGA occurs in about 3 of all congenital heart defects. What causes transposition of the great arteries The heart forms during the first 8 weeks of fetal development. The problem occurs in the middle of this time, allowing the aorta and pulmonary artery to become attached to the incorrect chamber. Some congenital heart defects may have a genetic link causing heart problems to occur more often in certain families. Most of the time this heart defect occurs by chance, with no clear reason for its development. Why is transposition of the great arteries a concern Babies with TGA have two separate blood flow circuits one that circulates oxygen poor blue blood from the body back to the body, and another that recirculates oxygen rich red blood from the lungs back to the lungs. Without an additional heart defect that allows mixing of oxygen poor blue and oxygen rich red blood, such as an atrial or ventricular septal defect or a patent ductus arteriosus, infants with TGA will  only have oxygen poor blue blood circulating through the bodya situation that is fatal. Even with an additional defect present that allows mixing, babies with transposition of the great arteries will not have enough oxygen in the bloodstream to meet the bodys demands for long. What are the symptoms of transposition of the great arteries The most common indication of TGA in a newborn is cyanosis blueish skin color in the first day of life. Cyanosis is noted in the first hours of life in about half of the infants with TGA, and within the first days of life in most of them. The degree of cyanosis is related to the presence of other defects that allow blood to mix, including an atrial septal defect a hole between the top chambers of the heart and a patent ductus arteriosusa fetal connection between the aorta and the pulmonary artery present in the newborn, which usually closes in the first few days after birth. The following are the other most common symptoms of TGA. However, each child may experience symptoms differently. Symptoms may include Rapid breathing. Fab 3000 V6 Keygen Torrent. Labored breathing.

The symptoms of TGA may resemble other medical conditions or heart problems. Always consult your childs doctor for a diagnosis. How is transposition of the great arteries diagnosed A pediatric cardiologist andor a neonatologist will be involved in your childs care. A pediatric cardiologist specializes in the diagnosis and medical management of congenital heart defects, as well as heart problems that may develop later in childhood. A neonatologist specializes in illnesses affecting newborns, both premature and full term. Cyanosis is the major indication that there is a problem with your newborn. Your childs doctor may have also heard a heart murmur during a physical examination.

Diagnostic testing for congenital heart disease varies by the childs age, clinical condition, and institutional preferences. Some tests that may be recommended include the following Chest X ray. A diagnostic test that uses invisible X ray beams to produce images of internal tissues, bones, and organs onto film. Electrocardiogram ECG. A test that records the electrical activity of the heart, shows abnormal rhythms arrhythmias, and detects heart muscle stress. Echocardiogram echo. A procedure that evaluates the structure and function of the heart by using sound waves recorded on an electronic sensor to produce a moving picture of the heart and heart valves. Cardiac catheterization. A cardiac catheterization is an invasive procedure that gives very detailed information about the structures inside the heart. Under sedation, a small, thin, flexible tube catheter is inserted into a blood vessel in the groin, and guided to the inside of the heart. Blood pressure and oxygen measurements are taken in the four chambers of the heart, as well as the pulmonary artery and aorta. Contrast dye is also injected to more clearly visualize the structures inside the heart. Treatment for transposition of the great arteries. Your child will most likely be admitted to the intensive care unit ICU or special care nursery once symptoms are noted. Initially, your child may be placed on oxygen, and possibly even on a ventilator, to assist his or her breathing. Intravenous IV medications may be given to help the heart and lungs function more efficiently. Other important aspects of initial treatment include the following A cardiac catheterization procedure can be used as a diagnostic procedure, as well as initial treatment procedure for some heart defects. A cardiac catheterization procedure will usually be done to evaluate the defects and the amount of blood that is mixing. Is ketosis dangerous You may have heard from your doctor that ketosis is a life threatening condition. If so, your doctor is confusing diabetic ketoacidosis DKA with nutritional ketosis, or keto adaptation. First, some semantics. Our body can produce, from fat and some amino acids, three ketone bodies a ketone refers the chemical structure where oxygen is double bonded to carbon sandwiched between at least 2 other carbons. These ketone bodies we produce are acetone, acetoacetone, and beta hydroxybutyrate B OHB. For anyone who is interested, they are the 3 most right structures on the figure, below. Why do we make ketones For starters, its a vital evolutionary advantage. Our brain can only function with glucose and ketones. Since we cant store more than about 2. Fortunately, our liver can take fat and select amino acids the building blocks of proteins and turn them into ketones, first and foremost to feed our brains. Hence, our bodys ability to produce ketones is required for basic survival. What is diabetic ketoacidosis When a diabetic usually a Type I diabetic, but sometimes this occurs in very late stage, insulin dependent, Type II diabetics fails to receive enough insulin, they go into an effective state of starvation. While they may have all the glucose in the world in their bloodstream, without insulin, they cant get any into their cells. Hence, they are effectively going into starvation. The body does what it would do in anyone it starts to make ketones out of fat and proteins. Heres the problem the diabetic patient in this case cant produce any insulin, so there is no feedback loop and they continue to produce more and more ketones without stopping. By the time ketone levels specifically, beta hydroxybutyrate approach 1. Furby Manual Game. M, the resulting p. H imbalance leads to profound metabolic derangement and the patient is critically ill. But this state of metabolic derangement is not actually possible in a person who can produce insulin, even in small amounts. The reason is that a feedback loop prevents the ketone level from getting high enough to cause the change in p. H that leads to the cascade of bad problems. A person who is said to be keto adapted, or in a state of nutritional ketosis, generally has beta hydroxybutyrate levels between about 0. M.   This is far less than the levels required to cause harm through acid base abnormalities. Keto adaption is a state, achieved through significant reduction of carbohydrate intake typically to less than 5. Specifically, the brain shifts from being primarily dependent on glucose, to being primarily dependent on beta hydroxybutyrate. This has nothing to do with what a diabetic patient is experiencing in DKA, but does illustrate how poorly informed and quick to react the medical community is. DKA and nutritional ketosis or keto adaptation have as much in common as a house fire and a fireplace.
