Patient-Centric Innovation: Superior Vena Cava Approach in Zero-Fluoroscopy

Patients undergo zero-fluoroscopy RFCA for atrioventricular nodal reentrant tachycardia (AVNRT) using the superior vena cava (SVC) or inferior vena cava (IVC) approach. The procedure is performed under conscious sedation and local infiltration anesthesia. A large-tip electrode catheter is used for mapping and ablation, guided by the EnSite NavX system, with ablation parameters set at 40 W power and 50°C temperature.
