Catheter ablation is an established treatment strategy for ventricular arrhythmias. However, the presence of intramural substrate poses challenges with mapping and delivery of radiofrequency energy, limiting overall success of catheter ablation. Advances over the past decade have improved our understanding of intramural substrate and paved the way for innovative treatment approaches. Modifications in catheter ablation techniques and development of novel ablation technologies have led to improved clinical outcomes for patients with ventricular arrhythmias. In this review, we explore mapping techniques to identify intramural substrate and describe available radiofrequency energy delivery techniques that can improve overall success rates of catheter ablation.

Catheter Technology

Catheter ablation has emerged as an important and effective treatment option for many recurrent ventricular arrhythmias. The approach to ablation and the risks and outcomes are largely determined by the nature of the severity and type of underlying heart disease. In patients with structural heart disease, catheter ablation can effectively reduce ventricular tachycardia (VT) episodes and implantable cardioverter defibrillator (ICD) shocks. For VT and symptomatic premature ventricular beats that occur in the absence of structural heart disease, catheter ablation is often effective as the sole therapy. Advances in catheter technology, imaging and mapping techniques have improved success rates for ablation. This review discusses current approaches to mapping and ablation for ventricular arrhythmias.

Growing Body

Catheter ablation is a rapidly expanding and evolving field. The advent of interventional techniques and advances in technology have allowed catheter ablation to supplant antiarrhythmic surgery for ventricular arrhythmia treatment. However, issues related to access and energy delivery limit the use of catheter ablation in some cases. Hybrid catheter-based and surgical techniques represent a novel approach to overcome these limitations. The hybrid technique combines the strengths and minimises the limitations of either catheter or surgical ablation alone. There is a growing body of evidence in the literature supporting the safety and efficacy of the hybrid surgical technique. This review aims to provide an overview of hybrid surgical-catheter ablation for ventricular arrhythmia.
