Key result
In patients after TOF repair, residual RVOTO was associated with significantly higher RV circumferential (P=0.02) and radial strain (P=0.02) and less interventricular dyssynchrony (P=0.03).
Why the study?
Does residual right ventricular outflow tract obstruction affect biventricular strain and synchrony in patients after repair of tetralogy of Fallot?
Observational (n=54)
Does residual right ventricular outflow tract obstruction affect biventricular strain and synchrony in patients after repair of tetralogy of Fallot?
p-value: p=0.02 for RV-CS and RV-RS
Residual RVOTO after TOF repair is associated with preserved RV strain and less interventricular dyssynchrony, suggesting a potential early protective effect on RV remodeling, despite a negative impact on LV strain.

Residual RVOTO after TOF repair may preserve early RV strain; hypothesis-generating for remodeling effects and needs prospective validation.
Latus et al. (2014) conducted an observational in Tetralogy of Fallot (TOF) (n=54). Residual right ventricular outflow tract obstruction (RVOTO) vs. No residual RVOTO was evaluated on Myocardial strain and dyssynchrony parameters (p=0.02 for RV-CS and RV-RS). In patients after TOF repair, residual RVOTO was associated with significantly higher RV circumferential (P=0.02) and radial strain (P=0.02) and less interventricular dyssynchrony (P=0.03).
