Coronary Sinus for Ablation of Ventricular Tachyarrhythmia and Supraventricular

Abstract

The advent of catheter ablation using radiofrequency current has provided electrophysiologists with the means to cure patients suffering from several tachyarrhythmia. The epicardial radiofrequency ablation has been developed for treatment both atrial and ventricular arrhythmia which is originating from epicardial regions. Although the epicardial ablation usually requires the direct approach to epicardial space with the subxyphoidal puncture, coronary sinus (CS) is special sites of epicardial ablation without epicardial puncture. In addition, recording of local activation from electrode catheters advanced into the CS often provides crucial information for diagnosis and localization of the arrhythmogenic substrate during ablation procedure. The CS ablation may be considered as one of the options to eliminate those arrhythmias in patients with arrhythmia who are resistant to standard endocardial catheter ablation. In this chapter, the catheter ablations from the CS targeting Wolf-Parkinson-White syndrome, atrial fibrillation, and ventricular arrhythmia are described.
