| Factor | Absolute RV strain |
| Description | Absolute RV (Right ventricular) strain was significantly smaller for patients with ASD (−8 ± 5%) than for patients with repaired TOF (−14 ± 5%; P < .001) |
| Biomarker | NA |
| Classification | A3 (clinical factor - disease & symptom) |

| Application | diagnosis and prognosis |
| Objective | investigate the relationship between interventricular dyssynchrony (IVD) using cine-tagged magnetic resonance imaging (MRI) and RV dysfunction in ACHD patients. |
| p Value | <0.001 |
| Conclusion | Quantification of IVD was possible using RV and LV strains derived from tagging MRI. IVD, represented as the time difference between LV and RV contractions, correlates with RV dysfunction. IVD may thus offer an indicator for RV failure in ACHD. |
