Differences in Collagen Deposition Based on Dichotomous Evaluation of Risk Factors
| Risk Factor (n) | Percentage Collagen Deposition | P Value |
|---|---|---|
| Time from Fontan >18 years (50) | 28.2±9.5 | 0.03 |
| Time from Fontan ≤18 years (17) | 22.3±9.1 | |
| Right ventricular morphology (37) | 22.6±9.3 | 0.27 |
| Left or mixed ventricular morphology (30) | 25.2±9.7 | |
| Mild or less AVVR (41) | 24.0±9.5 | 0.86 |
| More than mild AVVR (25) | 23.6±9.7 | |
| Normal ventricular function (50) | 24.1±9.7 | 0.84 |
| Mild ventricular dysfunction or worse (15) | 23.5±9.4 | |
| No diagnosis of PLE or PB (50) | 23.7±9.6 | 0.91 |
| Diagnosis of PLE or PB (17) | 24.0±9.2 | |
| BNP ≤100 pg/mL (56) | 23.8±8.8 | 0.39 |
| BNP >100 pg/mL (5) | 20.3±3.6 | |
| IVC pressure <15 mm Hg (46) | 24.1±9.7 | 0.73 |
| IVC pressure ≥15 mm Hg (21) | 23.2±9.2 |
AVVR indicates atrioventricular valve regurgitation; BNP, B‐type natriuretic peptide; IVC, inferior vena cava; PB, plastic bronchitis; PLE, protein‐losing enteropathy.
