Zero-Fluoroscopy Cardiac Ablation: Technology Is Moving Forward in Complex Procedures-A Novel Workflow for Atrial Fibrillation.

ABSTRACT: A fluoroscopy-based approach to an electrophysiological procedure is widely validated and has been recognized as the gold standard for a long time. The use of fluoroscopy exposes both the healthcare staff and the patient to a non-negligible dose of radiation. To minimize the risks associated with the use of fluoroscopy, it would be reasonable to perform ablation procedures with zero fluoroscopy. This approach is widely used in simple ablation procedures, but not in complex procedures. In atrial fibrillation (AF) ablation procedures, fluoroscopy remains the main technology used, in particular to guide the transseptal puncture. Main results and Implications. We present a workflow to perform a complete zero-fluoroscopy ablation for AF ablation procedures using a 3D electro-anatomical mapping system, intracardiac echocardiography and a novel steerable guiding sheath that can be visualized on the mapping system. We present two cases, one with paroxysmal AF and the other one with persistent AF during which we applied this novel workflow achieving a successful pulmonary vein isolation without complications and complete zero-fluoroscopy exposure.

Project description:Introduction Catheter ablation for atrial fibrillation (AF) is the most frequently performed cardiac ablation procedure worldwide. The majority of ablations can now be performed safely with minimal radiation exposure or even without the use of fluoroscopy, thanks to advances in 3-dimensional electroanatomical mapping systems and/or intracardiac echocardiography. The aim of this study was to conduct a meta-analysis to compare the effectiveness of zero fluoroscopy (ZF) versus non-zero fluoroscopy (NZF) strategies for AF ablation procedures. Methods Electronic databases were searched and systematically reviewed for studies comparing procedural parameters and outcomes of ZF vs. NZF approaches in patients undergoing catheter ablation for AF. We used a random-effects model to derive the mean difference (MD) and risk ratios (RR) with a 95% confidence interval (CI). Results Our meta-analysis included seven studies comprising 1,593 patients. The ZF approach was found to be feasible in 95.1% of patients. Compared to the NZF approach, the ZF approach significantly reduced procedure time [mean difference (MD): −9.11 min (95% CI: −12.93 to −5.30 min; p < 0.01)], fluoroscopy time [MD: −5.21 min (95% CI: −5.51 to −4.91 min; p < 0.01)], and fluoroscopy dose [MD: −3.96 mGy (95% CI: −4.27 to −3.64; p < 0.01)]. However, there was no significant difference between the two groups in terms of total ablation time [MD: −104.26 s (95% CI: −183.37 to −25.14; p = 0.12)]. Furthermore, there was no significant difference in the acute [risk ratio (RR): 1.01, 95% CI: 1.00–1.02; p = 0.72] and long-term success rates (RR: 0.96, 95% CI: 0.90–1.03; p = 0.56) between the ZF and NZF methods. The complication rate was 2.76% in the entire study population and did not differ between the groups (RR: 0.94, 95% CI: 0.41–2.15; p = 0.89). Conclusion The ZF approach is a feasible method for AF ablation procedures. It significantly reduces procedure time and radiation exposure without compromising the acute and long-term success rates or complication rates.
