Why the study?
Myocardial kinetic energy and its association with pulmonary regurgitation had not yet been investigated in patients with repaired tetralogy of Fallot.
Does MR tissue phase mapping reveal differential adaptation of biventricular myocardial kinetic energy in patients with repaired tetralogy of Fallot compared to normal controls?
Population
49 rTOF patients and 47 normal controls
Comparison
rTOF patients vs normal controls
Design
Prospective study
Key result
Patients with repaired tetralogy of Fallot exhibited disrupted biventricular kinetic energy balance, including significantly decreased diastolic LV %KEz (62% vs 72%) compared to normal controls.

Altered KE patterns may signal ventricular adaptation issues in rTOF; leaves open prognostic utility pending outcome validation.

Does MR tissue phase mapping reveal differential adaptation of biventricular myocardial kinetic energy in patients with repaired tetralogy of Fallot compared to normal controls?
MR tissue phase mapping reveals disrupted biventricular myocardial kinetic energy proportions in repaired tetralogy of Fallot, which correlate with pulmonary regurgitation.
Ke et al. (2022) conducted an observational in Repaired tetralogy of Fallot (n=96). Repaired tetralogy of Fallot vs. Normal controls was evaluated on Left and right ventricle myocardial kinetic energy (KE) in radial, circumferential, and longitudinal directions. Patients with repaired tetralogy of Fallot exhibited disrupted biventricular kinetic energy balance, including significantly decreased diastolic LV %KEz (62% vs 72%) compared to normal controls.
