Usefulness of banding of the pulmonary trunk with single ventricle physiology at risk for subaortic obstruction.

摘要: This study addresses the effects of early banding pulmonary trunk and subsequent management subaortic obstruction on attainment acceptable pre-Fontan hemodynamics in patients with a single left ventricle aorta arising from an outflow chamber. We report our experience 26 seen at institution between January 1984 December 1994 diagnosis double-inlet or tricuspid atresia transposed great arteries, who were initially managed artery first 6 months life. Pulmonary band placement was performed age 2.1 +/- 1.8 (mean SD). Associated aortic arch abnormalities present 8 (31%). There 19 (73%) underwent treatment Damus-Kaye-Stansel procedure ventricular septal defect (VSD) enlargement for significant gradient morphologically small VSD, alone conjunction Glenn Fontan procedure. Eighteen (69%) cardiac catheterization to assess their candidacy operation. Of this group, 16 classified as low moderate risk 2 high-risk candidates, based hemodynamic criteria. The cumulative mortality entire cohort 19%. Our results suggest that group can undergo effective initial palliative step, intervention ob- struction when it is documented highly suspected, parameters be achieved.
