Title (EN) SYSTEM AND METHOD USING CARDIAC-ESOPHAGEAL IMPEDANCE MAPPING TO PREDICT AND DETECT ESOPHAGEAL INJURY DURING CARDIAC ABLATION PROCEDURES
(FR) SYSTÈME ET PROCÉDÉ UTILISANT UN MAPPAGE D'IMPÉDANCE CARDIO-ŒSOPHAGIEN POUR PRÉDIRE ET DÉTECTER UNE LÉSION ŒSOPHAGIENNE PENDANT DES PROCÉDURES D'ABLATION CARDIAQUE
Abstract:
(EN) Exemplified methods and apparatus use assess electrical coupling between an ablative catheter and the esophagus using measurements of electrical impedance to beneficially predict esophageal damage prior to ablation and to detect on-going esophageal damage during ablation. The technology facilitates the determination of regional variations of electrical coupling between the esophagus and the ablation catheter to infer the risk of the esophagus and its nearby structures.
(FR) Des procédés et un appareil illustratifs utilisent l'évaluation de couplage électrique entre un cathéter ablatif et l’œsophage à l'aide de mesures d'impédance électrique pour prédire de manière avantageuse un dommage œsophagien avant l'ablation et pour détecter un dommage œsophagien en cours pendant l'ablation. La technologie facilite la détermination de variations régionales du couplage électrique entre l’œsophage et le cathéter d'ablation pour déduire le risque de l’œsophage et de ses structures proches.
