What LGE burden is significant in HCM?

LGE >=15% of LV mass doubles SCD risk and is now considered a major risk modifier supporting ICD consideration in HCM patients with intermediate 5-year risk by ESC model.

Where does LGE occur in HCM?

LGE in HCM typically occurs at RV insertion points (most common, low risk), within hypertrophied segments (patchy mid-wall), and at the apex (apical HCM variant).

Does LGE extent predict atrial fibrillation in HCM?

Yes. Extensive LGE correlates with LA fibrosis and AF burden in HCM. LA LGE quantification can predict AF recurrence after ablation in HCM patients.
