Balloon pulmonary valvuloplasty for isolated XXXX .

@entity1 @entity849 @entity256 @entity15882
Fifteen balloon pulmonary valvuloplasties (BPVs) were performed on 13 @entity1 and @entity1 with isolated @entity849 ( @entity849 ). There were no complications. Two @entity1 required repeat @entity15882 , one for failure, the other for @entity256 . At the time of the 13 latest BPVs, age ranged from three days to 13.1 years (mean 5.7 +/- SD 4.8 years). Average Doppler pulmonary valve pressure gradient preceding BVP was 75 +/- 22 mm Hg. At follow-up it was 25 +/- 9 mm Hg (p < .0001). Follow-up interval was 0.61 to 4.70 years (2.29 +/- 1.18). @entity256 occurred in 1/13 (8%) of the @entity1 . The remaining 12/13 (92%) showed highly satisfactory sustained gradient reductions. Doppler gradients preceding @entity15882 by as much as 4 months correlated highly with catheter gradients at time of @entity15882 , confirming that Doppler echocardiography is a highly accurate indication of @entity849 severity. Catheterization for @entity849 should therefore not be used for diagnostic purposes alone. @entity15882 can be performed safely, economically and effectively and is recommended as the treatment of choice for @entity1 and @entity1 with moderate to severe isolated @entity849 . For very young @entity1 , follow-up Doppler surveillance should be done semi-annually; for all others, annually.
