چکیده

Background: Assessment of cardiac performance parameters in patients with corrected tetralogy of Fallot with cardiac MRI short axis method compromises critical elements including papillary muscles, determination of end-diastolic and end-systolic cardiac phase, and furthermore, selection of the basal plane. Objectives: The study purpose was to evaluate the impact of basal plane selection on resulting cardiac performance parameters in cardiac MRI. Results: Variations of the basal plane caused significant changes (P < 0.005) of end-diastolic and end-systolic volumes. Differences were as large as 15.2% ± 5.8 regarding the left ventricle and up to 17.4% ± 6.1 for the right ventricle. Consequently, calculated stroke volume changed up to 19.2% ± 6.3 for the left and 22.7% ± 7.2 for the right ventricle. Ejection fractions of both ventricles varied significantly (P < 0.005). These differences were up to 19.1% ± 8.2. Conclusion: Variation of the basal plane by just one slice in cardiac MRI short axis method led to significant changes in the resulting cardiac performance parameters of both ventricles in patients with corrected tetralogy of Fallot.
