We describe a rare case of inappropriate implantable cardioverter defibrillator (ICD) therapy due to false sensing of electromechanical interference from diathermy as 'ventricular fibrillation (VF)'. This occurred during surgical removal of sternal wires under general anaesthesia. Postsurgical interrogation of ICD revealed the intracardiac electrogram showing the mechanical interference sensed as 'VF' by ICD and subsequent shock delivery.

Background: Current outcomes from catheter ablation for scar-dependent ventricular tachycardia (VT) are limited by high recurrence rates and long procedure durations. Personalized heart digital twin technology presents a noninvasive method of predicting critical substrate in VT, and its integration into clinical VT ablation offers a promising solution. The accuracy of the predictions of digital twins to detect invasive substrate abnormalities is unknown.

Premature ventricular contractions (PVCs) are a common finding in patients with surgically repaired congenital heart defects including transposition of the great arteries (D-TGA). While often asymptomatic, PVCs can sometimes lead to palpitations, dyspnea, and hemodynamic compromise, requiring therapeutic intervention. The arterial switch operation is the preferred treatment for D-TGA, but these patients have a 2% incidence of ventricular arrhythmias and 1% incidence of sudden cardiac death post-operatively.

This State of the Future Review describes and discusses the potential transformative power of digital twins in cardiac electrophysiology. In this 'big picture' approach, we explore the evolution of mechanistic modelling based digital twins, their current and immediate clinical applications, and envision a future where continuous updates, advanced calibration, and seamless data integration redefine clinical practice of cardiac electrophysiology. Our aim is to inspire researchers and clinicians to embrace the extraordinary possibilities that digital twins offer in the pursuit of precision medicine.

Aims: In repaired tetralogy of Fallot (rTOF), the septal anatomical isthmuses (AI), AI 3, between the ventricular septal defect (VSD) and pulmonary annulus, and AI 4, between the VSD and tricuspid annulus, are important ventricular tachycardia (VT) substrates when slow conducting. Our aim was to assess the influence of VSD characteristics, specifically the presence of muscular or fibrous tissue at its border, on the presence or absence of septal AIs, potentially related to VT.
Methods And Results: All consecutive rTOF patients who underwent electroanatomical mapping between January 2005 and March 2023 with an available surgical report providing VSD details (n = 91) were included.
