Tetralogy of Fallot
ICD-10 Q21.3ICD-11 LA88.2
Clinical Scenario

Tetralogy of Fallot with History of Sudden Cardiac Arrest or Sustained Ventricular Tachycardia

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.

Specific Situation

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.

Treatment Approach

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.

Full regimen, selection criteria, and clinical algorithm available via the link below.
