Dextro-transposition of the great arteries (D-TGA) is the second most common cyanotic congenital heart disease with variable coronary artery anatomy. Outcomes have improved significantly with the advent of the arterial switch procedure for this defect, with coronary artery anatomy being a very important parameter for both short and long term outcomes following surgical repair. Assessment of coronary artery anatomy is usually undertaken in the postnatal period by transthoracic echocardiography. Prenatal delineation will help with surgical planning, parental counseling and tertiary care referral as needed due to the critical importance of this variable in successful outcome. We describe our experience with prenatal coronary artery assessment in a cohort of patients with fetal diagnosis of D-TGA and highlight the importance of its assessment with both 2-dimensional (2D) and Color Doppler imaging, especially after 25 weeks gestation.
