Catheter ablation with remote magnetic navigation (RMN) can offer some advantages compared to manual techniques. However, the relevant clinical evidence for how RMN-guided ablation affects electrical storm (ES) due to ventricular tachycardia (VT) in patients with severe ischemic heart failure (SIHF) is still limited. ⋯ Acute catheter ablation with RMN is safe and effective to suppress ES in SIHF patients. RMN-guided catheter ablation can prevent VT recurrence and significantly reduce ICD shocks, suggesting that this strategy can be used as an alternative therapy for VT storm in SIHF patients with ICDs.

To evaluate diagnostic strategies in a rapid access chest pain clinic (RACPC) in the United Kingdom and to predict the economical and clinical impacts of incorporating fractional flow reserve by coronary computed tomographic angiography (FFRCT) into future pathways. ⋯ The DF algorithm overestimates the PTL of CAD supporting an extended role for coronary CTA. Strategies incorporating FFRCT may confer benefits in evaluating patients with stable chest pain.
