UNASSIGNED: A non-contractile transannular patch (TAP) in the right ventricular outflow tract (RVOT) contributes to @entity67 after @entity215 ( @entity215 ) repair. We compared regional right ventricular (RV) strain in repaired @entity215 with @entity849 ( @entity849 ) after balloon valvuloplasty to investigate the effects of TAP. Retrospective review of 26 cardiac magnetic resonance studies of @entity215 (n   =   13) and @entity849 (n   =   13) subjects matched by degree and duration of @entity338 ( @entity338 ). Feature tracking strain analysis was performed. Student's t tests, Pearson correlation, and linear regression were applied. RV ejection fraction (EF) was normal and similar between @entity215 and @entity849 (60 and 65%, respectively, p   =   0.8). RV 4-chamber Lagrangian longitudinal strain (RV 4ch @entity8433 ) was worse in both groups compared to normals but comparable to each other: -18.2 (95% CI -3.6 to -33) for @entity215 and -20.2 (95% CI -12.4 to -28) for @entity849 , p   =   0.5. RVOT @entity8433 was worse than RV 4ch @entity8433 in @entity215 , p   =   0.05, but not in @entity849 , p   =   0.19. There were no significant differences in RVOT strain between groups, p   =   0.18. RVOT strain and RV 4ch @entity8433 correlated positively with RV EF in @entity849 (r   =   0.72, p   =   0.003 and r   =   0.55, p   =   0.04). @entity338 degree correlated negatively with RVOT @entity8433 for @entity215 and @entity849 . @entity6475 is diminished in @entity849 and @entity215 subjects with preserved RV EF. TAP could explain worse RVOT strain in @entity215 . Longitudinal studies are needed to ascertain if @entity4266 predicts worsening of RV EF.
