| Variables | rTOF patients (n=25) | Healthy volunteers (n=10) | P value |
|---|---|---|---|
| Age at CMR (years) | 8.44±4.52 | 8.2±1.22 | 0.45 |
| Sex (male/female) | 15/10 (60%) | 7/3 (70%) | |
| Follow-up times after surgery (years) | 7.24±4.25 | – | |
| Heart rate (beat/min) | 82±14 | 91.2±17 | 0.13 |
| Body surface area (m2) | 0.98±0.34 | 1.09±0.16 | 0.09 |
| RVEDV index (mL/m2) | 127.8±36.13 | 83.11±6.18 | <0.001* |
| RVESV index (mL/m2) | 65.14±27.02 | 36.13±5.95 | <0.001* |
| EF (%) | 49.97±6.39 | 56.71±4.56 | 0.006* |
Data are expressed as mean ± standard deviation or n (%). *, represents a statistically significant difference. rTOF, repaired tetralogy of Fallot; EF, ejection fraction; RVEDV, right ventricular end-diastole volume; RVESV, right ventricular end-systolic volume.
