What is concordant ventriculoarterial connection?

What is concordant ventriculoarterial connection?

The ventriculoarterial connections were concordant, with parallel arterial trunks, but with the aorta posterior and to the right relative to the pulmonary trunk. The aortic valvar leaflets were in fibrous continuity with both atrioventricular valves, but the pulmonary valve was supported by a muscular infundibulum.

What is AV and VA concordance?

Abstract. Atrioventricular (AV) discordance with ventriculoarterial (VA) concordance is a rare form of congenital heart disease that consists of 5 different anatomic types.

What is Ventriculoarterial discordance?

We favor use of the term “ventriculoarterial” discordance to refer to a defect that involves incongruence of ventricular and arterial morphologies, as predicated on the loop rule.

What is AV discordance?

Atrioventricular and ventriculoarterial discordance, also known as congenitally corrected transposition of the great arteries (CCTGA), is a complex type of heart lesion that accounts for less than 1% of infants with congenital heart disease.

How do you calculate concordant value?

The concordance rate is the number of subjects that are concordant over the total number of subjects assessed. As can be seen in Figure 1, the concordance rate is calculated by adding the diagonal counts and dividing by the total number of subjects assessed.

What is DORV?

Double outlet right ventricle (DORV) is a congenital heart defect. There is a malformation of the fetus heart in the womb leading to the right ventricle that has the two major arteries, namely the aorta and pulmonary artery arising from it.

What is 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).
