CONCLUSION
In patients with TGA previously treated with the Mustard procedure, the
high prevalence of long term complications due to transvenous pacing and
baffle stenosis leads to clinically challenging situations. This report
represents the outcomes of a unique, safe, and feasible strategy used in
dilation of baffle stenosis using a mechanical rotating dilator sheath,
followed by balloon-expandable stenting of the SVC baffle with a jailed
non-functioning LA lead. Further studies are needed to assess the
efficacy and safety of the mechanical rotating dilator sheath in other
settings of CHD.
