A novel approach for effective superior vena cava isolation using the CARTO electroanatomical mapping system.

ABSTRACT:

Background

Previous studies have demonstrated that some patients have spontaneous right atrium (RA)-superior vena cava (SVC) conduction block, which could be utilized to isolate the SVC effectively by using the Rhythmia mapping system (Boston Scientific). However, employing this approach for SVC isolation using the CARTO electroanatomical mapping system (Biosense Webster) has not yet been clarified. This study aimed to evaluate the safety and efficacy of SVC isolation using the extended early meets late (EEML) tool with the CARTO system.

Methods

The patients who underwent SVC isolation using the CARTO system were enrolled in this study. The RA-SVC conduction block was visualized with an EEML tool. We prospectively assessed the safety and efficacy of SVC isolation using this
