Figure 15: A -Superior view of a heart with TGA after a Mustard operation. The aorta is folded anteriorly showing the sinus node artery (SN) close to the superior vena cava pathway (SVC) as the artery courses from the proximal RCA toward the crista terminalis. Stent placement in the SVC pathway could compress the sinus node artery. B – A stent (*) has been placed in the SVC pathway because of obstruction after a Mustard operation. The stent is very close to the LCx (arrow), which arises from the RCA, but does not compress it. (Reproduced from Marcora et al. [45] with permission). RCS- right coronary sinus, LCS- left coronary sinus, RAA- right atrium appendix. PV- pulmonary valve.
