Key result
TOF repair links to early RV strain decline that improves by 3 months.

How does right ventricular longitudinal peak systolic strain change over time following complete intracardiac repair for Tetralogy of Fallot?
Speckle tracking echocardiography is a feasible tool for evaluating right ventricular function after Tetralogy of Fallot repair, demonstrating an initial decline followed by significant improvement in RV strain at 3 months.

STE may aid early RV assessment post-TOF repair; leaves open whether it alters management versus standard echo.
Mandal et al. (2016) conducted a cohort in Tetralogy of Fallot (n=59). Complete intracardiac repair for Tetralogy of Fallot vs. Preoperative baseline was evaluated on Right ventricular longitudinal peak systolic strain (RV LPSS). Tetralogy of Fallot repair was associated with an early decrease in right ventricular strain that significantly improved at 3 months, with an overall procedural mortality rate of 3.4%.
