How do they fix transposition of the great vessels?

How do they fix transposition of the great vessels?

Arterial vs atrial: When anatomy ideal, hypothermic cardiopulmonary bypass and cardioplegic arrest done, aorta transected, left main and right main coronary buttons made, pulmonary artery transected, lecompte maneuver done, coronary buttons translocated to neoaorta, aorta is anastomosed to left v-a trunk, pulnomary artery anastomosed to reconstructed pulmonary trunk. Atrial switch operation may be required otherwise. Asdcl. Read more

What are the tests for transposition of the great vessels?

What are the tests for transposition of the great vessels?

ECHO, CATH., MRI: Echocardiogram diagnostic, emergency cardiac cath for rashking procedure if needed, and to determine coronary anatomy, if a concomitant vsd present, intracavitary pressures and shunt may possibly be determined. Cardiac MRI may be needed for concomitant vascular anomalies and assistance in situs inversus. Read more

What are the symptoms associated with transposition of the great vessels?

What are the symptoms associated with transposition of the great vessels?

Cyanosis: This is one of the cyanotic heart defects that leads to a "blue baby". The cause is the poorly oxygenated blood that is circulated to the body. See this link for more info: http://www. Ncbi. Nlm. Nih. Gov/pubmedhealth/pmh0002535/. Read more

How long is the recovery for a baby with transposition of the great vessels?

How long is the recovery for a baby with transposition of the great vessels?

6 weeks: The most common type of transposition of the great vessels (also known as transposition of the great arteries) is d-transposition or d-tga. Infants with d-tga only are usually discharged from the hospital less than one week following surgery. The often require medication for a few weeks after surgery. The breast bone, which is divided to perform the surgery, fully heals in 6 weeks. Read more

What is the definition or description of: Transposition of the great vessels?

What is the definition or description of: Transposition of the great vessels?

Aorta and PA mixed: A fatal condition or the aorta normally going to the rest of the body actually go to the lungs and the pulmonary artery which comes on the right ventricle only going to the lungs and some going to the brain and rest of the body Read more

Why is transposition of the great vessels fatal?

Why is transposition of the great vessels fatal?

2 parallel circ.: It results in 2 parallel circuits. Obviously if baby barely alive some mixing is present. The only crossover connections are the patent ductus arteriosus and the patent foramen ovale or asd. If a vsd present that favors mixing. If the PDA closes and the pfo not big enough, death may ensue unless an emergency rashkind procedure (balloon atrial septostomy) done to allow arteriovenous mixing &oxygenati. Read more

Please explain reasons why transposition of the great vessels is deadly?

Please explain reasons why transposition of the great vessels is deadly?

Abnormal connections: In tga (transposition of the great arteries) the aorta arises from the right ventricle and the pulmonary artery arises from the left ventricle. In this arrangement, oxygenated blood cannot reach the body, so oxygen delivery to the body is severely impaired. While there are treatments that can stabilize the circulation for a few days, an operation to "switch" the arteries is required as a newborn. Read more

Why is transposition of the great vessels so deadly?

Why is transposition of the great vessels so deadly?

Tga: There are 2 types, one D TGA needs immediate surgery in first days of life. Then you have good life expectancy, not necessarily if it is fixed in time. Other is L-TGA or corrected TGA and that one may not ever need surgery, however sometimes needs surgery and sometimes things may go worse since aorta is supported by a weaker ventricle-RV. Read more

Why is transposition of the great vessels such a big concern for a fetus?

Why is transposition of the great vessels such a big concern for a fetus?

Blue newborn!: Tga is a very severe cardiovascular anomaly because it can cause very low oxygen concentration in the blood going to the coronaries and carotids and prove lethal if untreated promptly and expertly. If a ventricular septal defect is present, the newborn can be more stable and interventions can be more planned and less emergent. Fetal life is ok - trouble starts as soon as the cord is clamped.

What is the most successful surgery for transposition of the great vessels?

What is the most successful surgery for transposition of the great vessels?

Depends on anatomy: Goal if possible is to achieve, atrioventricular and ventriculoarterial concordance as best possible. Some transpositions of the great arteries are congenitally corrected if baby born with atrioventricular and ventriculoarterial discordance. Is it d or l tga, how many concomitant anomalies are present. If d-tga, no vsd, good valves, no coronary anomalies, good lv and rv, ASD closure and jatene best. Read more

Does transposition of the great vessels happen because of genetics?

Does transposition of the great vessels happen because of genetics?

Yes and no: There are many genetic syndromes in which a cardiac malformation occurs, including transposition. However, there are other causes as well, such as the fetal effects of maternal diabetes, exposure to substances which can cause birth defects, and reduced folic acid in pregnancy. There are unknown patterns of malformations which we do not understand--heart defects with renal, ear, and vertebral. Read more

Do you normally get transposition of the great vessels in premature babies?

Do you normally get transposition of the great vessels in premature babies?

No: Transposition is a birth defect that occurs in the fetus early as the heart is forming. Tgere is no increased risk because a baby is premature. I am also not aware that tga causes prematurity. Read more

Does anyone have info on the janene heart operation for transposition of the great vessels? How does it work?

Does anyone have info on the janene heart operation for transposition of the great vessels? How does it work?

Jatene operation: This procedure is named after the surgeon who pioneered the technique. It is more commonly known as the arterial switch operation, because the transposed great arteries are "switched" back to where they belong. Moving the great arteries is a relatively easy procedure. The more difficult part of the procedure is relocating the coronary arteries, which are very small. Read more

Any info on the janene or other heart operation for transposition of the great vessels?

Any info on the janene or other heart operation for transposition of the great vessels?

Dr. Jatene: Dr. Jatene's operation is used to correct d transposition whenever possible given the proper anatomy present. Coronary buttons are translocated to the neoaorta, the aorta is anastomosed to the left ventricular ventriculoarterial valve, the le compte maneuver is done, the main pulmonary artery is anastomosed to the right ventriculo arterial valve trunk. That's it, the arterial switch procedure. Read more

I was born with transposition of the great vessels. I've had 4 open. Heart. Surgeries. I take enalapril and carvedilol. Do you think I qualify for ssi?

I was born with transposition of the great vessels. I've had 4 open. Heart. Surgeries. I take enalapril and carvedilol. Do you think I qualify for ssi?

Thanks for asking!: It depends on the functional status of your heart. If you had a mustard or senning operation, your right ventricle is pumping to your systemic circulation. This un-natural stress on the right ventricle often leads to heart failure, fatigue, and poor exercise tolerance. If you have these issues you would likely qualify for ssi. Read more

A women that have a surgery on her first day of life of transposition of great vessels can deliver vaginaly?

A women that have a surgery on her first day of life of transposition of great vessels can deliver vaginaly?

Hard to say: If you or a specific friend are wondering about childbirth, you/they should first discuss it at length with their docs. The advisability of pregnancy varies with cardiac status & one answer cannot be right for all women. You might want to meet with a geneticist, because there is ~4% risk of CHD in your baby, 10% if dad also has any heart defect. Many with this defect go on to have families, good luck Read more
