BACKGROUND: @entity943 are a frequent late complication of Fontan procedures. Conversion to an extracardiac conduit combined with reducing right atrial size should improve hemodynamics and reduce the development of @entity591 . More effective control may be achieved by interrupting @entity943 and atrial pacing. METHODS: Between May 1997 and October 2001, 6 @entity1 underwent a revision of their intracardiac Fontan @entity254 . The conversion included an extracardiac conduit insertion, limited right atrial maze procedure, and pacemaker placement. Ages ranged from 14 to 34 years (mean, 22.8 years) at an average of 14.6 +/- 4.4 years after their original Fontan procedure. All of the @entity1 had medically uncontrollable @entity4710 with markedly reduced exercise tolerance. RESULTS: All of the @entity1 survived with an average hospital stay of 16.7 days. Exercise tolerance has improved in all 6 @entity1 , and @entity591 have either decreased (n = 2) or disappeared (n = 4). Two @entity1 are taking antiarrhythmic medications other than digoxin. Follow-up is a mean of 28.5 months. CONCLUSIONS: Limited right atrial maze procedure, @entity955 , and pacemaker implantations are worthwhile additions to simple conversion to an extracardiac conduit in the failing Fontan.
