Cardiac magnetic resonance indices reflecting pulmonary regurgitation burden after tetralogy of Fallot repair.
Clinical Radiology 2017 October
AIM: To investigate cardiac magnetic resonance (CMR)-derived parameters to determine a convenient index reflecting the degree of pulmonary regurgitation (PR) after Tetralogy of Fallot (TOF) repair.
MATERIALS AND METHODS: Sixty-three patients (age at CMR study, 23.6 [10.2-34.7] years, 55.6% male) underwent CMR after TOF repair. PR was quantified using ventricular stroke volume difference and phase-contrast mapping of the main pulmonary artery flow. In both approaches, the PRV index (PRVI) and the PR fraction (PRF) were calculated and correlated to the right ventricle end-diastolic volume index (RVEDVI) and the right ventricle end-systolic volume index (RVESVI).
RESULTS: No statistically significant difference was observed between the PR volumes and the PRF measured by the stroke volume difference or the phase-contrast method. The PRVI was better correlated to RVEDVI and RVESVI than the PRF.
CONCLUSION: The PRVI exhibits more correlation to the RVEDVI than PRF. Thus, it could be a preferable parameter to reflect the PR burden.
