Catheter Ablation of Haemodynamically Not-tolerated Electrical Storm in Structural Heart Disease

Emergency catheter ablation is defined as ablation performed within 48 hours of hospital admission

Patients randomized to the stepped-care strategy arm will receive treatment through a systematic, stepwise protocol beginning with anti-arrhythmic drugs, followed by sedation and anesthesia, and progressing to haemodynamic mechanical support devices if earlier treatments prove ineffective. Catheter ablation will be reserved as the final rescue intervention.
