Multi-center, Observational, Retrospective Comparison of the Feasibility, Safety, and Efficacy of Real Zero Fluoroscopy Versus Conventional Fluoroscopic Catheter Ablation With and Without 3D System Support: Propensity Matched Study

Catheter ablation is a well-established treatment to treat patients with a wide scope of heart arrhythmias.

The study is an investigator-initiated, retrospective analysis of prospectively collected data. The study population consists of patients with right-sided arrhythmias who underwent zero-fluoroscopy catheter ablation between the years 2016 and 2018 in 3 centers and a propensity score matched patients group of patients who:

• underwent conventional fluoroscopy guided catheter ablation without 3D system (Ensite/Carto) support
• underwent conventional fluoroscopy guided catheter ablation with 3D system (Ensite/Carto) support

Covariates for matching will be:

• arrhythmia type
• age of a patient
• number of diagnostic catheters used during a procedure
• type of a diagnostic catheter used during a procedure]
