[Catheter ablation of ventricular tachycardia-Update 2023]

Area of Science:

• Cardiology
• Electrophysiology
• Cardiac Surgery

Context:

• Ventricular tachycardia (VT) management is challenging, particularly in patients with severe cardiomyopathy.
• Myocardial structural damage in cardiomyopathy is a key factor in VT occurrence and mechanisms.

Purpose:

• To outline the goal of catheter ablation in understanding and treating patient-specific VT mechanisms.
• To describe catheter ablation as a causal therapy for VT.

Summary:

• Catheter ablation involves first understanding the patient-specific VT mechanism.
• Second, the arrhythmogenic ventricular areas are ablated and electrically inactivated.
• This modifies the myocardium to prevent VT triggering, offering causal therapy.

Impact:

• Catheter ablation provides an effective treatment option for patients suffering from VT.
• It enables causal, rather than just symptomatic, management of this serious cardiac arrhythmia.
