A thorough understanding of supravalvar anatomy and the use of multimodality imaging are essential for safe and effective ablation of supravalvar arrhythmias.
Supports supravalvar anatomy mastery and multimodality imaging in ablation; leaves open prospective validation of protocols.
Supravalvar ablation has now been well documented to be the ideal mode for ablating specific forms of ventricular tachycardia, atrial tachycardia, and accessory pathways. A studied appreciation of the anatomy of the supravalvar region is a prerequisite for electrophysiologists to safely and effectively approach these arrhythmias. In addition, the consistent ability to correlate the recorded electrograms with fluoroscopic anatomy and intracardiac ultrasound images enhances the chance of successful elimination of supravalvar arrhythmias.
