What are the types of TGA?
What are the types of TGA?
Dextro-TGA is often simply called “TGA.” However, “TGA” is a broader term that includes both dextro-TGA (d-TGA) and levo-TGA (l-TGA), or congenitally corrected TGA, which is not discussed here.
What is the difference between L-TGA and D-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 is the difference between simple and complex D-TGA?
Simple and complex d-TGA Stenosis of valves or vessels may also be present. When no other heart defects are present it is called ‘simple’ d-TGA; when other defects are present it is called ‘complex’ d-TGA.
Which vessels are switched in patients with transposition of great arteries?
Transposition of the great arteries (TGA) is a heart defect that occurs from birth (congenital). The two major arteries that carry blood away from the heart — the aorta and the pulmonary artery — are switched (transposed).
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.
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).
What is the difference between TGA and ccTGA?
What is Levo transposition of great arteries?
What is complex transposition of the great arteries?
Transposition of the great arteries (TGA) is a serious, rare heart problem in which the two main arteries leaving the heart are reversed (transposed). The condition is present at birth (congenital heart defect).
Is TGA and TGV the same?
Transposition of the great vessels (TGV), also referred to as transposition of the great arteries (TGA), is a relatively rare congenital heart defect and the second-most common type of defect that causes babies to turn blue.
What is Fontan heart surgery?
The Fontan procedure refers to any surgical procedure that leads to systemic flow of venous blood to the lungs without passing through a ventricle. In 1971, Fontan and Baudet (1) described a surgical procedure for repair of tricuspid atresia that built on experimental and clinical research from the 1940s.
What is Ventriculoarterial 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 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.
What does Levocardia mean?
Strictly speaking, levocardia means that the cardiac apex is left sided. Isolated levocardias are those hearts that are left sided when situs inversus is present. This anomaly occurs in less than 1% of all patients with congenital cardiac malformation compared with a 2% incidence of dextrocardia in patients with CHD.
What are the causes of transposition of the great arteries?
Overview. In transposition of the great arteries,the origins of the main arteries leading away from the heart — the aorta and the pulmonary artery — are switched (transposed).
What is the treatment for transposition of the great arteries?
Before surgery. Your baby’s doctor may recommend several options to help manage the condition before corrective surgery.
What are the symptoms of transposition of the great arteries?
Lack Of Appetite And Poor Weight Gain. Infants affected by TGA often exhibit a lack of appetite and poor weight gain as a manifestation of their heart defect.
How is transposition of the great arteries diagnosed?
How is transposition of the great arteries diagnosed? If, during pregnancy, a routine prenatal ultrasound or other signs raise suspicion of a congenital heart defect in the fetus, a cardiac ultrasound of the baby in uterowill usually be the next step. The cardiac ultrasound can usually detect transposition of the great arteries (TGA).
