Key result
Zero-fluoroscopy right-sided SVT ablation achieves ~99% acute procedural success.
Why the study?
Fluoroscopy entails detrimental long-term radiation effects and orthopedic risks from lead aprons, prompting the need to describe and evaluate a step-by-step fluoroless catheter ablation approach for right-sided supraventricular tachycardia.
Observational (n=86)
Yes
A zero-fluoroscopy approach for right-sided SVT ablation using 3D electroanatomic mapping is highly feasible and acutely successful, eliminating radiation exposure for patients and staff.
Fluoroscopy has long been indispensable in electrophysiology procedures. However, the detrimental long-term effects of x-rays on both patients and healthcare workers are well documented. Moreover, the routine wearing of lead aprons is associated with orthopedic complications in the long term. The emergence of new technologies, such as electroanatomic mapping systems and intracardiac echocardiography, has significantly reduced the need for fluoroscopy, thereby alleviating these concerns. This article describes our step-by-step approach to fluoroless catheter ablation of right-sided supraventricular tachycardia and evaluates its implementation in clinical practice through a retrospective case series. Between May 2024 and April 2025, 86 consecutive patients underwent ablation using this strategy. The findings support existing evidence that zero-fluoroscopy interventions are feasible, efficient and safe.

Altmann et al. (2026) conducted an observational in Right-sided supraventricular tachycardia (n=86). Fluoroless catheter ablation was evaluated on Acute procedural success. A zero-fluoroscopy approach for right-sided supraventricular tachycardia ablation achieved an acute procedural success rate of 98.8% and was feasible without fluoroscopy conversion in 82.5% of cases.
