Why the study?
Does surgical pulmonary valve replacement improve ventricular strain and synchrony in patients with repaired tetralogy of Fallot?
Does surgical pulmonary valve replacement improve ventricular strain and synchrony in patients with repaired tetralogy of Fallot?
Surgical pulmonary valve replacement in patients with repaired tetralogy of Fallot improves left ventricular strain and synchrony but does not significantly alter right ventricular global strain.
No takes yet. Share an insight, caveat, or question.
PVR improves LV strain without altering RV strain in repaired TOF; leaves open whether these mechanics changes guide timing or predict outcomes.
Balasubramanian et al. (2018) studied this question.
