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

How are anomalous pulmonary venous return & transposition of great vessels different?

How are anomalous pulmonary venous return & transposition of great vessels different?

Both cause cyanosis: Both are congenital heart defects that cause cyanosis (less oxygen than normal in the arterial blood.) however that is the only similarity. In transposition of the great arteries, the primary problem is that the aorta arises from the right ventricle instead of the left ventricle. In t(total)apvr, the primary problem is that the pulmonary veins do not connect directly with the left atrium. ...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

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

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

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 is the long term prognosis for transposition of the great vessel/ arterial switch done in 1997?

What is the long term prognosis for transposition of the great vessel/ arterial switch done in 1997?

Long term outlook: for Arterial Switch Operation (ASO) is excellent. Long-term outcomes after ASO of greater than 95 percent survival at 20 and 25 years following discharge have been reported from a number of centers. Thanks for trusting HealthTap! ...Read more

What exactly is the difference between anomalous pulmonary venous return & transposition of great vessels?

What exactly is the difference between anomalous pulmonary venous return & transposition of great vessels?

See below: Anomalous pulmonary venous return means taht 1 or more of the pulmonary veins returns blood from the lung to the right atrium instead of the left atrium. Transposition is a defect where the aorta origninate from the right ventricle and the pulmonary artery comes from the left ventricle which is backwards. ...Read more

How to differentiate between anomalous pulmonary venous return & transposition of great vessels as the underlying disease?

How to differentiate between anomalous pulmonary venous return & transposition of great vessels as the underlying disease?

Ultrasound: Pediatric cardiologist use ultrasound (an echocardiogram) to identify the type of congenital heart defect. In anomalous pulmonary venous return, the pulmonary veins do not connect to the left atrium in a normal manner. In transposition of the great arteries, the aorta is connected to the right ventricle and the pulmonary artery is connected to the left ventricle (backwards). ...Read more

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

What does "transposition of the great arteries" mean?

TGA: Tga refers to a type of congenital heart disease in which the aorta is connected to the right ventricle (instead of the left ventricle) and the pulmonary artery is connected to the left ventricle (instead of the right ventricle). This heart defect usually requires surgical repair within the first several days to weeks of life. ...Read more

What is the life expectancy of adult who had a transposition of the great arteries surgery?

What is the life expectancy of adult who had a transposition of the great arteries surgery?

Generally good: An adult likely underwent a senning or mustard procedure (atrial switch operation) for tga. The 20 year survival is reported to be about 90%, but many patients have abnormal heart rhythms and some have abnormal heart function. This group of patients has a reduced life expectancy, estimated by some to be 45-50 years (63 years after an arterial switch operation). ...Read more

How does one differentiate between anomalous pulmonary venous return & transposition of great vessels?

How does one differentiate between anomalous pulmonary venous return & transposition of great vessels?

TAPVR vs. TGA: The diagnosis of anomalous venous return (TAPVR) vs. transposition of the great vessels (TGA) is made in the newborn period. Simply put, the TAPVR baby usual presents 'pink' (no blueness) while the TGA baby will appear 'blue'. There are several variations of both TAPVR and TGA. The diagnosis can be accurately diagnosed by transthoracic ECHO and all are surgically operable with excellent results. ...Read more

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
