Monomorphic ventricular arrhythmias (MMVA) are not uncommon in athletes,1,2 yet their presence appropriately raises concern among practitioners for possible increased risk of sudden cardiac death (SCD) during sports activity and competition. While all MMVA detected in athletes warrant further evaluation,1 a majority of MMVA in this population are likely to be benign. In some instances of so…

Sustained ventricular tachycardia (VT) and ventricular fibrillation (VF) are typically a manifestation of significant structural heart disease and often associated with a high risk of sudden cardiac death. Implantable cardioverter defibrillators (ICDs) remain the mainstay of therapy for prevention of sudden cardiac death associated with these arrhythmias.1 However, ICDs treat the arrhythmia after…

Idiopathic ventricular arrhythmias (IVAs) usually originate from the specific anatomical structures. For the past decade, major IVA origins from both endocardial and epicardial sites have been increasingly recognised (see Table 1).1–3 Catheter ablation of IVAs is usually safe and highly successful, but can sometimes be challenging because of the anatomical obstacles. Therefore, understanding the…

Prior to the widespread availability of left ventricular assist devices (LVADs), many end-stage heart failure patients were forced to fight over scarce transplant resources or face the reality of impending death. For those considered transplant-ineligible, due to medical or psychosocial factors, symptom palliation and end-of-life care were the only available options. This all changed dramatically…

Catheter-based ablation has been a well-established tool in the treatment of ventricular tachycardia (VT). However, the effectiveness of catheter ablation may be limited by its ability to access sites of arrhythmogenic tissue and achieve adequate lesion size in target areas without risking collateral damage. Antiarrhythmic surgery would be an effective alternative in such situations. Despite the…

Catheter-based Mapping to Characterise Ventricular Tachycardia
Catheter-based mapping of the left ventricle (LV) to characterise the substrate and origin of ventricular tachycardia (VT) was thought to involve a much greater level of risk and therefore not to be pursued. Mark proved the naysayers wrong with his careful and methodical approach to evaluating the LV endocardium.
What made these…

Ventricular tachycardia (VT) is a life-threatening sequela found in patients with cardiomyopathy. ICDs can terminate ventricular arrhythmias, but recurrent device shocks lead to reduced quality of life and are associated with higher mortality.1–5 Radiofrequency catheter ablation has emerged as an effective treatment for VT refractory to anti-arrhythmic therapy and has also been shown to reduce…
