Anatomic subtype and survival after reconstructive operation for XXXX .

@entity1 @entity1699 @entity4794 @entity1146 @entity472 @entity2333
We conducted a retrospective study of 78 @entity1 who underwent palliative reconstructive operation for @entity1699 representing an entire consecutive experience between 1983 and 1991 to identify predictors of mortality that might enable more appropriate triage of @entity1 to either reconstruction or transplantation. Twenty-nine @entity1 had @entity2333 , mitral @entity1146 ; 18 had @entity472 , @entity4794 ; 20 had @entity2333 and @entity4794 ; and 11 had miscellaneous forms of @entity1699 . There were 29 hospital deaths (37%). A worst preoperative pH (p = 0.01) and immediate preoperative pH (p = 0.03) less than the median were predictors of hospital mortality. The anatomic subgroup @entity2333 , @entity4794 (p = 0.06) had a possible increased hospital mortality. One @entity1 was lost to follow-up. The Kaplan-Meier survival estimate among hospital survivors was 34% at 3 years and 25% at 5 years. The anatomic subgroup @entity2333 , mitral @entity1146 (p = 0.02) had a worse late outcome (11% 3-year survival) whereas the subgroup @entity472 , @entity4794 (p = 0.04; 76% 3-year survival) had a better late outcome. There were no other significant predictors of late survival other than immediate prerepair pH (p = 0.05). Interpretation of this experience is complicated by the large number of different surgical techniques used for both first-stage neonatal reconstruction and the Fontan procedure plus introduction of the bidirectional Glenn shunt as an intermediate step midway through the experience. Nevertheless in this time frame and with the variety of techniques used, this experience demonstrates that @entity1 with @entity2333 , mitral @entity1146 , particularly those who have been very acidotic in the neonatal period, are least likely to do well with the reconstructive approach to @entity1699 and are the most appropriate subgroup to be directed to transplantation. @entity1 with @entity472 , @entity4794 have an excellent late outcome with the reconstructive approach.
