What is atrioventricular and Ventriculoarterial discordance?

What is atrioventricular and Ventriculoarterial 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.

What is discordant Ventriculoarterial connection?

Definition. A rare congenital cardiovascular abnormality in which the aorta arises from the right ventricle and the pulmonary artery arises from the left ventricle. [ from NCI]

What is atrioventricular orifice?

The right atrioventricular orifice (right atrioventricular opening) is the large oval aperture of communication between the right atrium and ventricle in the heart. Situated at the base of the atrium, it measures about 3.8 to 4 cm.

What does concordance mean in heart?

Precordial concordance, also known as QRS concordance is when all precordial leads on an electrocardiogram are either positive (positive concordance) or negative (negative concordance).

What is concordant Arioventricular?

connections in which the atrial chambers connect to the morphologically appropriate ventricles.

What is VA discordance?

What lies in the atrioventricular groove?

The atrioventricular groove contains the coronary sinus, which is the largest vein of the heart and lies posteriorly opening into the right atrium. The interatrial groove is covered anteriorly by the ascending aorta and the main pulmonary artery.

What are the components of right atrioventricular orifice?

The right atrioventricular valve, located between the right atrium and right ventricle, is one of the most complex and variable structures within the human body. It has been conventional wisdom that this valve, commonly referred to as the tricuspid valve, has 3 leaflets: anterior, septal, and posterior 1, 2, 3.

What is discordance in ECG?

ST-elevation is “excessively discordant” when the ST-elevation (measured at the J-point) is > 0.25 or 25% the depth of the S-wave. ST-depression is “excessively discordant” when the ST-depression (measured at the J-point) is > 0.3 or 30% the height of the R-wave.

What is AV discordance?

What is Situs Solitus with Levocardia?

Situs solitus is the normal arrangement of abdominal organs with levocardia (Fig. 3) and is associated with a less than 1% incidence of congenital heart disease.
