Key result
Post-Mustard superior tunnel narrowing is common on angiography but rarely produces significant pressure gradients.
Why the study?
Anatomical details of the altered atrial anatomy following the Mustard procedure in surgically corrected transposition were not well delineated angiographically.
Design
Observational angiographic study

Angiographic tunnel narrowing rarely produces gradients in corrected transposition; leaves open its clinical relevance in larger cohorts.
Observational (n=10)
Angiography following the Mustard procedure reveals invariable narrowing of the superior limb of the V-shaped tunnel, though this rarely causes a significant pressure gradient.
Rizk et al. (1973) conducted an observational in Surgically corrected transposition (n=10). Mustard procedure was evaluated on Anatomical details of the altered atrial anatomy and pressure differences. Angiographic evaluation following the Mustard procedure showed invariable narrowing at the superior limb of the V-shaped tunnel, but a significant pressure difference was present in only 1 patient.
