Abstract Ablation of persistent and long-standing persistent atrial fibrillation (AF) is a potentially complex procedure that carries a lower success rate than ablation for paroxysmal AF. Predictors of recurrence include…
Abstract Cryoballoon ablation is a safe and predictable toolset to generate a reliable large-area pulmonary vein antral modification for the treatment atrial fibrillation. Its reproducibility amongst a wide range of…
Abstract This chapter discusses the fundamentals of intracardiac mapping as it relates to the mapping and ablation of cardiac arrhythmias. The initial sections are dedicated to the basis and methodology…
Abstract Three-dimensional (3-D) mapping systems have been developed and used for more than 20 years to map more complex arrhythmias that cannot easily be treated with traditional electrophysiological approaches. These…
Abstract Atypical atrial flutters refer to a spectrum of arrhythmias that vary in location and circuit dimensions. These arrhythmias are often recognized after catheter ablation or surgical treatment of atrial…
Abstract Remote catheter navigation to perform cardiac ablation can offer improved and stable catheter movement, as well as reaching locations that might be difficult to reach manually. Remote navigation systems…
Abstract In animal experiments, cooled ablation overcomes the limitations of standard radiofrequency (RF) delivery by cooling the catheter tip and preventing an impedance rise, thus allowing higher power delivery and…
Abstract Focal atrial tachycardia (AT) is the least common form of supraventricular tachycardia (SVT). It accounts for approximately 5% to 15% of SVT cases undergoing catheter ablation. Focal AT is…
Abstract Cardiac imaging studies play an essential role in contemporary invasive electrophysiologic mapping and ablation procedures. From guiding appropriate patient selection, to preprocedure definition of the substrate, to intraprocedural demonstration…
Abstract Cryoablation is a safe and efficient energy for treating a variety of arrhythmic substrates at risk of atrioventricular (AV) block during ablation, including AV nodal reentrant tachycardia and septal…
