Non Fluroscopic Mapping As a New Modality of Management For Supraventricular Tachyarrhythmia

Abstract

nterventional cardiac electrophysiologic mapping and ablation is now increasingly utilized as a main line of treatment for different cardiac tachyarrhythmias.

Conventional fluoroscopically guided mapping and ablation using multiple endocardial catheters allowed treatment of simple forms of tachyarrhythmias as AVNRT, AVRT, typical CTI dependant AFL, and idiopathic VT with the achievement of high success rates and low incidence of complications. However, mapping and ablation of more complex arrhythmias, including focal atrial tachycardias, many forms of macrorentrant atrial tachycardias, ischaemic VT, and AF still repsresent a challenge for electrophysiologists.

In the last few years, novel mapping technologies had evolved that revolutionized the mapping and treatment of complex cardiac arrhythmias, one of these technologies is the electroanatomic CARTO ® mapping system.

This study is an attempt to to evaluate the EA mapping system as a new modality of managment for different forms of SVT. To achieve this goal, we studied I 05 pts. with previously documented attacks of SVT admitted to the Cardiology Department (Nancy University Hospital - France) for electrophysiological mapping and ablation. Seventy eight were males (71.6%), 27 (28.4%) were females with a mean age of 55 ± 15.8 years.
