Esophageal Temperature Monitoring
Real-time temperature surveillance during posterior left atrial ablation to prevent thermal injury to the adjacent esophagus.
Full Definition
Esophageal temperature monitoring involves the placement of temperature sensors in the esophagus during left atrial ablation procedures to prevent thermal injury from radiofrequency energy delivery. The esophagus lies in close proximity to the posterior left atrial wall, and excessive heating can result in serious complications including esophageal perforation or atrioesophageal fistula. Temperature probes with multiple sensors are positioned to monitor the esophageal wall temperature during posterior wall ablation, with energy delivery typically limited when temperatures exceed 38-40°C.
Usage
Usage note: Critical safety measure for posterior left atrial procedures. Temperature thresholds vary by institution.
