Assessment of right ventricular diastolic function in pediatric patients with repaired tetralogy of Fallot by cardiovascular magnetic resonance and echocardiography

ConclusionsCMR-derived parameters showed good agreement with TTE parameters in determining RV DD. CMR-derived E/e ′ was proved to be the most effective in identifying RV DD.Clinical relevance statementThis study demonstrated the feasibility and efficacy of CMR in assessing diastolic function in pediatric patients. RV DD was presented in over half of patients according to current TTE guidelines, highlighting the need for assessing RV diastolic function during follow-up.Key Points• Routinely acquired cine and phase-contrast cardiovascular magnetic resonance (CMR) images yielded right ventricular (RV) diastolic parameters which demonstrated good agreement with transthoracic echocardiography (TTE) measurements.• There was a high prevalence of RV diastolic function impairment in pediatric patients with repaired tetralogy of Fallot (rTOF).• CMR is a reliable complementary modality of TTE for RV diastolic function evaluation.
