Article Synopsis
- - Patients with repaired tetralogy of Fallot are prone to ventricular tachycardia and sudden cardiac death, with most arrhythmias linked to specific slow-conducting areas in the heart known as SCAIs.
- - The study compared a "prophylactic" approach, which involved ablating SCAIs regardless of whether VT was induced, to a "historical" approach that used VT induction to guide treatment, focusing on reducing complications and the need for implantable cardioverter-defibrillators (ICDs).
- - Results showed that patients who underwent prophylactic ablation had no major arrhythmic events over a median follow-up of 21 months, whereas 29% of the historical group

Article Synopsis
- A study explored how adjusting conduction velocity (ϴ) in computational models of persistent atrial fibrillation (AF) can enhance the accuracy of simulations compared to actual patient outcomes post-ablation.
- Researchers analyzed data from 37 patients who underwent ablation, finding that adjusting ϴ improved the model's agreement with clinical results, increasing accuracy from 46% to 65%.
- The results suggest that personalized adjustments of ϴ, especially in patients with significant left atrial fibrosis and higher BMI, could make simulations more relevant for predicting arrhythmia recurrence after treatment.
