Speckle tracking may aid dyssynchrony detection in repaired TOF; leaves open whether it informs resynchronization or outcomes.
Does 2D speckle tracking identify interventricular and right-intraventricular dyssynchrony and its associated factors in patients with surgically repaired tetralogy of Fallot compared to healthy controls?
Two-dimensional speckle tracking can effectively detect interventricular and right-intraventricular dyssynchrony in patients after TOF repair, which is primarily driven by reduced RV myocardial deformation and QRS prolongation.
