Implantable cardioverter-defibrillator use in elderly patients receiving cardiac resynchronization: A meta-analysis

Hellenic Journal of Cardiology, 2019
Background: Implantable cardioverter-defibrillators (ICDs) and cardiac resynchronization therapy (CRT) reduce sudden cardiac death and all-cause mortality in patients with heart failure with reduced ejection fraction (HFrEF).

T-Wave Oversensing with Contemporary Implantable Cardioverter–Defibrillators

Journal of Cardiovascular Development and Disease, 2023
Background: Implantable cardioverter–defibrillators (ICDs) need to reliably detect ventricular tachycardia (VT) and ventricular fibrillation (VF) while avoiding T-wave oversensing (TWOS), which is associated with a risk of inappropriate therapies.

External defibrillation on an implantable defibrillator [PDF]

Journal of Anesthesia, 2013
To the Editor: Despite the best efforts of healthcare providers, guideline-conform treatment failure is expected to occur, particularly in real-world emergency situations [1]. In the case reported here, a 79-year-old man with a history of coronary artery disease and implantation of a cardioverter defibrillator (ICD) presented to the emergency room with

A Dual‐Modal Wearable PPG Smartwatch with AI‐Enhanced Correction for High‐Accuracy and Continuous AF Burden Assessment

Advanced Science, EarlyView.
ABSTRACT Atrial fibrillation (AF) increases the risk of stroke and heart failure, yet accurate quantification of AF burden in daily life remains difficult. Although smartwatch photoplethysmography (PPG) supports continuous monitoring, complex rhythms and signal noise can impair burden estimation.

A Novel Pak1 Activator Ameliorates ER Stress for HFpEF Therapy

Advanced Science, EarlyView.
Chronic metabolic stress is a major contributor to HFpEF progression. Under prolonged metabolic stress, Pak1 activity becomes impaired, contributing to disrupted ER proteostasis, cardiomyocyte apoptosis, fibrosis, and diastolic dysfunction. Mechanistically, Pak1 overexpression activates the ERK1/2–MNK1–eIF4E signaling axis, promotes translational ...

A Randomized Controlled Trial Comparing the TruSteer and FXD Double Curve Delivery Systems for Left Atrial Appendage Occlusion With the Watchman FLX Pro Device—The GUIDE‐LAAO Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Deflectable delivery systems have been introduced to enhance coaxial alignment and procedural efficacy during left atrial appendage occlusion (LAAO), yet randomized comparisons with conventional fixed‐curve systems are lacking. Aims The GUIDE‐LAAO trial evaluated whether the TruSteer deflectable delivery system is non‐inferior to ...

Coronary Flow in Hypertrophic Obstructive Cardiomyopathy—Immediate Effects of Alcohol Septal Ablation

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Hypertrophic cardiomyopathy is associated with alterations in coronary microvascular function which have variable pathophysiologic mechanisms, and variable reversibility acutely and chronically following alcohol septal ablation (ASA).

Indications of Implantable Defibrillator

Journal of Interventional Cardiology, 1995
Implantable cardioverter defibrillators are devices capable of detecting and terminating ventricular tachycardias or fibrillations. They are utilized in the treatment of severe ventricular tachyarrhythmias, and their efficacy in the prevention of sudden death is demonstrated.
