Brugada syndrome (BrS) is a genetic heart disease that predisposes individuals to ventricular arrhythmias and suddencardiacdeath. In this setting, epicardial substrate ablation has emerged as a promising alternative for symptomatic patients.
An international consensus statement on how to treat atrial fibrillation with catheter or surgical ablation has been published in EP Europace, a journal of the European Society of Cardiology (ESC), and was recently presented at EHRA 2024, a scientific congress held April 7-9 in Berlin, Germany.

Implantable cardioverter defibrillator (ICD) prevents suddencardiacdeath (SCD) in patients with ischemic cardiomyopathy (ICM). Catheter ablation has been shown to effectively reduce ventricular tachycardia (VT) recurrence, yet its efficacy in patients without an ICD implantation remains uncertain.
Recent advancements in catheter ablation for structural ventricular tachycardia (VT), such as high-density mapping and cardiac imaging-based detection of target areas, have significantly improved the efficacy of ablation procedures.
Patients with repaired tetralogy of Fallot are at risk of ventricular tachycardia (VT) and suddencardiacdeath. Historically, risk stratification electrophysiologic studies involved programmed ventricular stimulation with VT induction guiding implantable cardioverter-defibrillator (ICD) implantation or VT ablation.
Ventricular tachycardia (VT) is a common consequence of both ischemic and non-ischemic heart diseases, often leading to suddencardiacdeath. Enhanced sympathetic nerve activity has been implicated in the initiation of VT.
Suddencardiacdeath remains the main killer of adults in industrialized countries and reentrant ventricular arrhythmia (VA) is its main underlying mechanism1.
Cardiovascular mortality, driven by suddencardiacdeath, is the main reason for dying while waiting for heart transplantation (HTx). Ablation will be performed with the use of a substrate-based approach in which the myocardial scar is mapped and ablated while the heart remains predominantly in sinus rhythm.
Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a disease characterised by fibrofatty replacement of the ventricular myocardium due to specific mutations, leading to ventricular arrhythmias and suddencardiacdeath. Emerging evidence suggests that combining flecainide and bisoprolol may be efficacious.
All study participants never received alcohol septal ablation or surgical myectomy during follow-up. LV-GLS were derived from cine cardiac MRI by using feature tracking method. Circulation, Volume 150, Issue Suppl_1 , Page A4142952-A4142952, November 12, 2024. The primary endpoint was SCD or SCD-equivalent events.
HCM is estimated to occur in ~1 in 500 young adults , making it among the most common inherited cardiac disorders. It is the most common underlying cause of suddencardiacdeath ( SCD ) in asymptomatic young individuals — which raises the question of whether to screen those involved in regular ( high performance ) athletic activity?
Furthermore, it includes the latest recommendations which specifically address AF and thromboembolic risk assessment, anticoagulation, left atrial appendage occlusion, AF catheter or surgical ablation, and risk factor modification and AF prevention. As such, the Class of Recommendation for catheter ablation has been upgraded.
(Please note, this doesn’t work and should not be attempted in early ischemic VT, though few case reports of RF ablations during VT storm li- Juan Qu et al AMJS 2924 ) Final message The relationship between Ischemia and VT is poorly understood, (rather than to say complex.)
