What is Dextro transposition of the great arteries?

Dextro-Transposition (pronounced DECKS-tro trans-poh-ZI-shun) of the Great Arteries or d-TGA is a birth defect of the heart in which the two main arteries carrying blood out of the heart – the main pulmonary artery and the aorta – are switched in position, or “transposed.”

What is the difference between D-TGA and L-TGA?

The two common forms of transposition include D-TGA, which presents with cyanosis early in life, and L-TGA, which on the other hand, may permit survival to adulthood without being diagnosed in childhood.

What are the types of TGA?

There are three types of thermogravimetric analyzers: suspension system, top-loading system and horizontal system.

What is the difference between TGA and CCTGA?

Congenitally corrected transposition of the great arteries (CCTGA) is a rare heart defect in which the heart’s lower half is reversed. It is also called L-TGA. It is different from and much less common than “regular” transposition of the great arteries (TGA or D-TGA).

How is L-TGA diagnosed?

L-TGA can be present in infants, children and adults. In most cases, there is no known cause for L-TGA and there are no specific genetic syndromes seen with L-TGA. This heart condition is usually diagnosed with an echocardiogram — an ultrasound of the heart — or by a fetal echocardiogram before birth.

What other defects can most commonly occur with TGA?

Complications of untreated TGA include:

  • Heart valve problems.
  • Heart muscle problems or problems with the arteries that supply blood to the heart muscle.
  • Abnormal heart rhythm.
  • Heart failure.
  • Lung problems.
  • Death.
