Keywords: Myocardium, Heart
Motivation: Patients with repaired Tetralogy of Fallot (rTOF) have varied cardiac structures, yet there's a current lack of analysis on their cardiac kinetic energy.
Goal(s): We aim to assess myocardial kinetic energy (KE) differences between patients and normal groups.
Approach: We utilized tissue phase mapping images combined with MATLAB programs to calculate myocardial kinetic energy.
Results: The results revealed differences in myocardial kinetic energy values between patients and normal groups. Besides, significant variations were observed in the proportional values across three directions, along with notable differences in the KE systolic-to-diastolic ratio of the right ventricle.
Impact: Differential myocardial kinetic energy serves as a novel indicator for evaluating cardiac function in rTOF patients. It aids in early detection of cardiac abnormalities, potentially identifying the optimal timing for pulmonary valve replacement surgery.
