Study summary

Primary Objective: To observe, record, and analyze the workflow and guidance system efficiency of these two surgical procedures, including placement time, location, and the number of successful placements.

Secondary Objective: To compare the differences between the two procedures and observe and record the process of transitioning to intracardiac ultrasound guidance by experienced physicians performing both workflows. The primary focus is on the time spent on target steps and related complications, with the aim of reducing radiation exposure during the procedure with the new technology.

Read the detailed description

The aim of this study is to compare the safety and efficiency of two workflows (with or without FAM Dx) using CARTO® 3 System for PSVT ablation. The results will later be compared with another 3-dimentional mapping system (Ensite™) historically

What researchers measure

Primary outcomes

  1. The success of ablation

    defined by elimination of accessory pathway and slow nodal pathway or modification of the slow nodal pathway with which a PSVT upto 3 reentrants would not be induced

    Time frame: 1Year

Secondary outcomes

  1. The complication rates

    including the occurrence of AV block needing pacemaker, or pericardial effusion needing drainage, or use of fluoroscopy

    Time frame: 1Year
