Patients underwent catheter ablation using PFA with the goal of ablating artificial intelligence (AI)-guided spatiotemporal dispersion. Biatrial mapping of spatiotemporal dispersion was obtained using the Volta AF-Xplorer™ (Volta Medical, Providence, RI, USA). Re-conducting PVs and extra-PV regions of interest exhibiting dispersion were ablated using the Farawave™ catheter (Boston Scientific, Marlborough, MA, USA). This catheter was used either in the basket or flower configuration sequentially centered at an estimated geometric center of AI-detected dispersion regions. The mean procedure and biatrial mapping times were 75 ± 12 and 14 ± 7 min, respectively, and no fluoroscopy was used. No complications occurred, and sinus rhythm conversion by ablation was obtained in 23 patients (92%). The rate of freedom from any atrial arrhythmia at 6 months was 88%.

Many patients, however, present without an ICD. The role of catheter ablation in this high-risk group is unclear, particularly for short-term in-hospital outcomes. We assessed associations between ablation and in-hospital outcomes among ICD-naive VT patients using a large national dataset. We conducted a retrospective study using the National Inpatient Sample (2016-2021), identifying adult hospitalizations with VT. Patients with prior ICDs or ICD implantation during the same admission were excluded. The cohort was divided into those who underwent catheter ablation versus those managed without ablation. Multivariable logistic regression and 1:1 propensity score matching (PSM) adjusted for demographic, clinical, and hospital factors. The primary outcome was in-hospital mortality; secondary outcomes included ST-elevation myocardial infarction (STEMI), sepsis, major adverse cardiac events (MACEs) (death, STEMI, or cardiogenic shock), cardiogenic shock, tamponade, mechanical circulatory support (MCS), acute heart failure, and prolonged hospitalization (≥7 days). Of 2,214,424 VT hospitalizations, 32,640 (1.5%) underwent catheter ablation.
