In patients with Tetralogy of Fallot, episodes of cardiac arrest or sustained ventricular tachycardia represent a high-risk presentation requiring prompt secondary prevention. This subset of patients carries a significant risk of sudden cardiac death and warrants a specific, guideline-directed management approach distinct from routine TOF follow-up.
This protocol applies to patients with a confirmed diagnosis of Tetralogy of Fallot who have experienced cardiac arrest or sustained ventricular tachycardia — a history that identifies them as candidates for secondary prevention of sudden cardiac death.
Management in this setting centres on implantable device-based therapy for secondary prevention. The complete indications, patient selection criteria, and management algorithm — including all procedural and follow-up considerations — are detailed in the full structured protocol.

An ICD should be implanted for secondary prevention of SCD (patients with cardiac arrest or sustained VT) (IC recommendation).
