Background: The substrates for arrhythmias in myocarditis and ischemic heart disease (IHD) are different, but it is yet to be determined whether there is a difference in outcomes following catheter ablation (CA) for ventricular tachycardia (VT) associated with these two conditions. This study aimed to compare outcomes after CA of VT in patients with myocarditis versus those with IHD.
Methods: Patients undergoing CA for sustained VT confirmed by endomyocardial biopsy as myocarditis, and patients with IHD experiencing sustained VT undergoing CA were retrospectively enrolled from February 2017 to March 2023.

Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC) is a right ventricular disease caused by desmosomal gene mutations leading to fibro-fatty replacement of the myocardium causing ventricular arrhythmias such as ventricular tachycardia (VT). A 59-year-old female presented with new onset VT manifesting as shortness of breath and chest discomfort. Diagnostic workup revealed right ventricular dilation/dysfunction on echocardiogram, VT with left bundle branch block (LBBB) and diffuse T wave inversions (TWIs) on EKG.

Long QT Syndrome (LQTS) is a rare hereditary canalopathy, characterized by prolonged ventricular repolarization, which can lead to malignant tachyarrhythmias at a young age. Treatment typically involves healthy lifestyle changes and β-blocker therapy. In specific cases, the implantation of an implantable cardioverter defibrillator (ICD) can be an option.

Background: In cases of electrical storm, identifying the etiology is essential, as patients with reversible causes do not benefit from implantable cardioverter defibrillator (ICD). Given the diversity of pharmacologic and nonpharmacologic management tools available for hemodynamically unstable patients in electrical storm, all must be considered and tailored to each individual patient.
Case Description: This report describes a 36-year-old female without prior cardiac history who presented in ventricular fibrillation (VF) electrical storm.

Background: Fatal arrhythmic events (FAEs), such as sudden cardiac death (SCD) and fatal ventricular arrhythmias, are a devastating complication in patients with coronary artery disease (CAD). Therefore, in this study we aimed to assess the incidence of FAEs in more recent Japanese patients with CAD and to examine whether risk stratification of FAEs can still be feasible using the left ventricular ejection fraction (LVEF).
Methods And Results: In the CREDO Kyoto PCI/CABG registry cohorts-2 and -3, there were 25,843 patients with LVEF data who received a first coronary revascularization (LVEF ≤35% group: N=1,671, 35%
