Impact of respiration on electroanatomical mapping of the right atrium: implication for cavotricuspid isthmus ablation

Abstract

Electroanatomical mapping systems' accuracy may be strongly influenced by respiration movements. The current study showed that automatic respiratory gated acquisition resulted in a better visualization of CTI, and this determines a relevant reduction in fluoroscopy and RF times.

General Anesthesia is Not Superior to Local Anesthesia for Remote Magnetic Ablation of Atrial Fibrillation

“…Several factors may explain this difference, including the occurrence of unexpectedly large breathing movements, which is often challenging during manual RF ablation under conscious sedation. Some tools have been developed to overcome these difficulties: new technologies (cryoablation), and new software with respiration gating acquisition . The properties of the magnetic catheter tip with constant application on the tissue may also minimize the deleterious impact of the deep breaths.…”

Impact of respiration gating on image integration guided atrial fibrillation ablation

“…Previous work by Beinart et al [8] has confirmed that more accurate electroanatomical maps can be obtained by respiratory gating. The only study investigated the impact of respiratory gating on RF ablation was about cavotricuspid isthmus (CTI) ablation procedures [13]. In this study, respiratory gated acquisition resulted in a better visualization of CTI and a significant reduction in fluoroscopy and RF times.…”

Computational ECG mapping and respiratory gating to optimize stereotactic ablative radiotherapy workflow for refractory ventricular tachycardia

“…Respiratory motion compensation is commonly used by electroanatomic mapping systems during invasive catheter ablation procedures to minimize catheter movement artifacts, improving accuracy and contact force. 18 , 19 , 20 It is also used routinely for stereotactic body radiotherapy to treat intrathoracic tumors such as lung cancer and was shown to decrease PTV size and toxicity to normal tissue. 18 Presently, however, respiratory gating is uncommonly used in cardiac SAbR; abdominal binders or no mitigation of respiratory motion have been the most common approaches.…”
