Noncontact mapping for radiofrequency ablation of complex cardiac arrhythmias.
Radiofrequency (RF) catheter ablation is the current treatment of choice for several cardiac arrhythmias. The conventional approach utilizing intracardiac electrograms during sinus rhythm and during tachycardia has inherent limitations, including limited two-dimensional fluoroscopic imaging and limited ability to evaluate several potential sites for ablation then go precisely to the most suitable site. Recently, a noncontact mapping system has been developed that can be used to perform single beat high resolution mapping of cardiac arrhythmias. In this report, we describe the advantage of utilizing the system in facilitating a successful outcome in 5 patients with different complex arrhythmias.
