[Table/Fig-14b]:

L-TGA.

L-TGA (Levo-TGA)= aorta anterior and to the left of pulmonary artery AV and VA discordance (Aorta arising from right sided LV and PA arising from left sided RV)
Incidence [13]	1 in 13,000 live births. M>F.
Association	VSD, pulmonary stenosis (valvular or subvalvular), abnormalities of systemic AV (tricuspid) valve and conduction system anomalies
Syndromes	Laurence-Moon-Biedl syndrome
Imaging features Plain	Cardiomegaly with straight left upper heart border	Pulmonary Plethora (in TGA + VSD)	LA enlargement and pulmonary venous congestion (TGA + severe left AV valve regurgitation)
Imaging features specific	Echo Direct demonstration MRI and CT for demonstration of cardiac/extracardiac anomalies
Management [12]	Palliative: Modified BT shunt (in pts with severe PS) Pulmonary artery banding for uncontrollable CHF in infancy Definitive repair: Classic repair: leaves the anatomical RV as systemic ventricle Anatomic repair: makes the anatomical LV as systemic ventricle; less risk of post-op TR and RV failure
