Elective Sternotomy With Fluoroscopic Guidance for the Removal of a Residual Implantable Cardioverter Defibrillator Lead: A Case Report and Literature Review.

Infectious myocarditis (IM) and infective endocarditis (IE), sometimes associated with infection of the surrounding mediastinal tissue or embolic complications caused by residual implantable cardioverter defibrillator (ICD) lead material embedded in the ventricle, present a significant challenge for cardiac surgeons due to the difficulty of precisely locating the old intracardiac pacing lead remnants because of the heart's continuous movement. We present the case of successful two-stage elective sternotomy extraction of two residual defibrillator leads, one trapped in the left innominate vein, easily removed after veinotomy without cardiopulmonary bypass (CPB), and the other embedded intramyocardially in the inferior wall of the right ventricle, successfully removed under CPB after fluoroscopic guidance. The patient was discharged four weeks post-operation without complications.

We hypothesised that following first ICD therapy, combining different treatment strategies would be associated with a reduction in the risk of subsequent therapy compared to single strategies alone.
Methods: Data was collected from consecutive patients undergoing ICD implantation at King's College Hospital between January 2009 and December 2019.
Left bundle branch area pacing in patients with transthyretin cardiac amyloidosis: a case series.
Eur Heart J Case Rep
January 2025
Division of Cardiology, Internal Medicine III, Hamamatsu University School of Medicine, Hamamatsu, Shizuoka 431-3192, Japan.
Background: Transthyretin cardiac amyloidosis is associated with various arrhythmias, including atrioventricular block. Despite this correlation, established treatments for transthyretin cardiac amyloidosis-associated arrhythmias are lacking. Left bundle branch area pacing is a promising physiological pacing technique.

Visible-light-driven photocatalytic uranium extraction based covalent organic frameworks (COFs) are green and sustainable, but their performance is severely restricted by a strong exciton effect. Herein, inspired by the physiology of cardiac pacing, a novel fluorine-based COF (PyF-DaS-COF) with a biomimetic electronic pump has been fabricated and used for the photocatalytic extraction of uranium. Both experimental and theoretical calculations confirm that strongly electronegative fluorine plays a crucial role in exciton dissociation and charge transfer.

Pacing Clin Electrophysiol
January 2025
Department of Cardiology, The Second Affiliated Hospital of Soochow University, Suzhou, Jiangsu, China.
Background: Conduction system pacing (CSP) has been reported to improve clinical outcomes in comparison of right ventricular pacing (RVP). However, the performance between CSP and RVP on the risk of new-onset atrial fibrillation (AF) remains elusive.
Methods: Four online databases were systematically searched up to July 1, 2024.
