OBJECTIVE
To describe
the use of self expanding stents in treating long segment stenosis of
aortopulmonary shunts (APS) in adults.
DESIGN
Clinical
records, catheterisation data, cineangiograms, and operation notes of
four consecutive patients undergoing stent implantation since December
1994 were studied retrospectively.
SETTING
A tertiary
referral centre for cardiac disease.
SUBJECTS
Four patients
underwent cardiac catheterisation because of clinical deterioration.
Their age ranged between 23 and 32 years. The underlying diagnosis was
complex cyanotic heart disease in all. Three had a stenotic
interposition graft, and one had a classic Blalock shunt.
RESULTS
There was one
technical failure owing to migration of the stent distal to an ostial
stenosis. The ability index, resting oxygen saturation, and exercise
tolerance improved in the remainder. Their medium term results have
been excellent.
CONCLUSIONS
This
technique may further palliate adult patients with complex congenital
heart disease, though the long term patency of stents is unknown.
