Multidetector computed tomography guidance in complex cardiac ablations.

Abstract

Radiofrequency ablation of complex cardiac arrhythmias has undergone significant evolution in the past decade, with the development of technology enabling better anatomic and electrophysiologic mapping of abnormal cardiac tissue. In this paper, we will discuss the role of pre-procedural and post-procedural multidetector computed tomography, with specific focus on the anatomic assessment of pulmonary vein and left atrial anatomy in the ablation of atrial fibrillation. We will also consider how the integration of both multidetector computed tomography and electroanatomic computer-based imaging may contribute more broadly to the management of a variety of complex ablation procedures.
