| Factor | right ventricular systolic dysfunction |
| Description | Total scar extension, expressed as % of total endocardial area, was significantly higher in patients with left and right ventricular systolic dysfunction [4.5% (±3.2) vs 2.8% (±2.3), p = 0.016 and 3.5% (±3.0) vs 2.6% (±1.9), p = 0.03, respectively]. |

| p Value | 0.03 |
| Conclusion | Patients with rCHD involving the right ventricle show electrical scars with variable distribution, not necessarily matching with sites of surgical lesions. Scar extension correlates with some of the risk factors for lifethreatening arrhythmias in CHD, such as prolonged QRS. Thus EVM could be considered an additional tool in the assessment of risk stratification in this particular population. |
