Characteristics of the Perinatal Outcome Groups at the Time of Prenatal Diagnosis (n=241)
| LTFU (n=11) | Termination (n=15) | Fetal Demise or Neonatal Death (n=97) | Neonatal Survival (n=118) | |
|---|---|---|---|---|

| GA at diagnosis, wk | 24.5±5.3 | 20.4±4.1 | 25.9±5.0 | 29.1±5.8 |
| CTA ratio | 0.40±0.12 | 0.38±0.12 | 0.47±0.12 | 0.40±0.11 |
| TV annulus diameter z-score | 4.7±3.3 | 6.0±3.1 | 6.8±3.0 | 4.3±2.7 |
| ≥ Moderate TR | 9 (82) | 13 (87) | 86 (89) | 84 (71) |
| TR jet velocity,* m/s (n=174) | 2.4±0.6 | 2.0±0.7 | 2.3±0.6 | 2.8±0.7 |
| No antegrade PV flow | 5 (45) | 9 (60) | 65 (67) | 46 (39) |
| Pulmonary regurgitation | 4 (36) | 3 (20) | 44 (45) | 24 (20) |
| Depressed RV function | 3 (27) | 5 (33) | 37 (38) | 31 (26) |
| Depressed LV function | 3 (27) | 1 (7) | 22 (23) | 11 (9) |
| Pericardial effusion | 3 (27) | 2 (13) | 33 (34) | 17 (14) |
| Hydrops | 0 (0) | 1 (7) | 10 (10) | 4 (4) |
Values are presented as mean±standard deviation or frequency (%). CTA indicates cardiothoracic area; GA, gestational age; LTFU, lost to follow-up; LV, left ventricle; PV, pulmonary valve; RV, right ventricle; TR, tricuspid regurgitation; and TV, tricuspid valve.
