Echocardiographic assessment of transposition of the great arteries and congenitally corrected transposition of the great arteries

Abstract

Echocardiographic assessment of patients with transposition of the great arteries and congenitally corrected transposition requires awareness of the morphology and commonly associated lesions. The pre-operative echocardiography should include a full segmental and sequential analysis. Post-operative assessment is not possible without awareness of the type of surgical procedure performed and consists of assessing surgical connections and residual lesions.

Congenitally corrected transposition of great arteries: a case series of five unoperated African children

“…Pulmonary stenosis occurs in 53% of cases [1,11]. Obstruction may be at sub-valvular, valvular or supravalvular level [11].…”

“…Pulmonary stenosis occurs in 53% of cases [1,11]. Obstruction may be at sub-valvular, valvular or supravalvular level [11]. Sub-valvular pulmonary obstruction is due to the origin of the pulmonary outflow between the gap created by atrial and ventricular septal malalignment.…”

“…Transposition of the great vessels is a group of congenital heart defects involving an abnormal spatial arrangement of any of the great vessels[ 139 ]. Congenital heart diseases involving only the primary arteries (pulmonary artery and aorta) belong to a sub-group called TGA: the aorta aligns with the RV and the pulmonary artery aligns with the LV[ 140 ]. It is the fourth most common type of major cardiac defect[ 141 ] and the second most common cyanotic lesion after ToF[ 140 ]; if not treated, it is the leading cause of SCD in neonates and infants[ 142 ].…”

Important echocardiographic assessments in case of TGA are position of the great arteries in PLAX or subcostal views, presence of ASD and VSD, presence of LVOT obstruction, eventual anomalies of coronary arteries[ 140 ].…”
