Preferred Label : Congenital heart defects, multiple types, 6;
Symbol : CHTD6;
CISMeF acronym : CHTD6; DTGA3;
Type : Phenotype, molecular basis known;
Alternative titles and symbols : Transposition of the great arteries, dextro-looped 3; DTGA3;
Description : The more common form of transposition of the great arteries, dextro-looped TGA, consists
of complete inversion of the great vessels, so that the aorta incorrectly arises from
the right ventricle and the pulmonary artery incorrectly arises from the left ventricle.
(In the less common type of TGA, levo-looped TGA, the ventricles are inverted instead)
(Goldmuntz et al., 2002). This creates completely separate pulmonary and systemic
circulatory systems, an arrangement that is incompatible with life. Patients with
TGA often have atrial and/or ventricular septal defects or other types of shunting
that allow some mixing between the circulations in order to support life minimally,
but surgical intervention is always required. For a discussion of genetic heterogeneity
of dextro-looped transposition of the great arteries, see 608808.;
