Summary

The aim of the present work is to analyze the capacity of high resolution mapping systems to determine the precise location of the AV node and peri-nodal slow-conducting pathways, using standard recording parameters, but also off-line additional filter changes and additional techniques (conduction velocities, isochrones and dV/dt). The investigative team plan a prospective monocentric study.

Detailed high resolution mapping of the Koch triangle and neighboring areas will be collected through the RHYTHMIA HDx 3D electro-anatomical mapping system and the multipolar ORION catheter. This sample will consist of 2 groups of patients: the first will include patients referred for AVNRT ablation and the second will include control patients (without AVNRT), referred for another indication requiring similar mapping system. If visualized, position of the slow pathway and AV node will be compared with the ablation areas, which will be set conventionally under fluoroscopy.

Conditions

  • Atrioventricular Nodal Reentry Tachycardia
  • Supraventricular Tachycardia

Interventions

PROCEDURE

high resolution cartography

High-resolution electro-anatomical mapping will be performed in each group with the RHYTHMIA HDx system to obtain an activation and voltage map of the Koch triangle and surrounding areas.
