How common is CCTGA?

How common is CCTGA?

How common is CCTGA? About 0.5%–1% of all babies born with heart defects have CCTGA. This means there are about 5,000–10,000 people in the United States with CCTGA.

What is corrected transposition?

Corrected transposition of the great arteries is a very rare heart defect in which the heart’s lower two chambers, the ventricles, are reversed in their positions. It affects about 1 in 25,000 births and occurs equally in boys and girls.

What is L transposition of great arteries?

Levo- or L-looped transposition of the great arteries (L-TGA) is a rare form of congenital heart disease characterized by atrioventricular (AV) and ventriculoarterial discordance (figure 1). It is also commonly referred to as congenitally corrected TGA, double discordance, or ventricular inversion.

How common is Mesocardia?

Furthermore, approximately 25% of patients are manifested as dextrocardia or mesocardia. 2 On the other hand, mesocardia is extremely rare with reported incidence of 0.2 per 10 000 deliveries.

What does congenitally corrected transposition of the great arteries?

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).

Is Mesocardia normal?

Thus, from the stand-point of position of chambers, the type of hearts found in mesocardia resembled those found in dextrocardia and levocardia. If the spleen was normal, then the atrial situs in all cases agreed with that of the viscera and the venous return was normal.

Is transposition of the great arteries rare?

Transposition of the great arteries is a serious but rare heart defect present at birth (congenital), in which the two main arteries leaving the heart are reversed (transposed). The condition is also called dextro-transposition of the great arteries.
