Coupling Models of Resistive Valves to Muscle Mechanics in Cardiac Fluid–Structure Interaction Simulations

International Journal for Numerical Methods in Biomedical Engineering, Volume 41, Issue 12, December 2025.
Scheme of the cardiac fluid‐structure interaction model including valve‐wall interaction. ABSTRACT To accurately simulate all phases of the cardiac cycle, computational models of hemodynamics in heart chambers need to include a sufficiently faithful model of cardiac valves.

A surgical resection case of myxoma arising from the posterior wall of the left atrium complicated with complete atrioventricular block

Journal of Cardiothoracic Surgery
An 80-year-old female was referred to our institution due to transient right upper limb weakness. Transthoracic and transesophageal echocardiography revealed a tumor in the left atrium. The tumor was attached to the posterior wall of the left atrium near

Predicting acute decompensated heart failure using circadian markers from heart rate time series

ESC Heart Failure, Volume 12, Issue 6, Page 4095-4107, December 2025.
Circadian metrics—amplitude, mesor, and acrophase—derived from a wrist‐worn heart rate monitor can predict acute decompensated heart failure (ADHF) up to 21 days before onset. In 65 post‐ADHF patients, an LSTM model achieved 74% sensitivity, and 73% specificity trained on 21‐day sequences. These findings support circadian rhythm analysis as a promising

Phenotype characterization of heart failure with preserved ejection fraction in medical device and surgical trials

ESC Heart Failure, Volume 12, Issue 6, Page 3878-3898, December 2025.
This systematic review identified 24 clinical trials of medical device and surgical interventions for HFpEF, with 16 demonstrating at least safety and feasibility, but little evidence of long‐term benefit. Phenotype‐based responses suggest that certain interventions may benefit specific HFpEF subgroups, yet most trials suffered from heterogeneous ...

Comparison of Total Intravenous Anesthesia Versus Volatile Anesthesia on Arrhythmia Inducibility and Clinical Outcomes During Catheter Ablation for Ventricular Tachycardia

Journal of Arrhythmia, Volume 41, Issue 6, December 2025.
This study has identified that the maintenance of general anesthesia with TIVA as opposed to volatile anesthesia is associated with increased inducibility of ventricular tachycardia during catheter ablation procedures. 84.5% of TIVA patients were inducible compared to only 15.5%.s ABSTRACT Introduction Catheter ablation is highly efficacious for the ...

Successful Treatment With Ivabradine for Junctional Ectopic Tachycardia–Induced Cardiomyopathy With Hypoplastic Left Heart Syndrome

Journal of Arrhythmia, Volume 41, Issue 6, December 2025.
A patient with hypoplastic left heart syndrome developed heart failure due to tachycardia‐induced cardiomyopathy from junctional ectopic tachycardia. Conventional antiarrhythmic therapy was ineffective, but ivabradine successfully controlled the arrhythmia and improved both ventricular function and heart failure.

Zero Fluoroscopy Ablation of Arrhythmias in Patients With Congenital Heart Disease

Journal of Arrhythmia, Volume 41, Issue 6, December 2025.
Zero‐fluoroscopy radiofrequency ablation using 3D electroanatomic mapping was performed in 42 patients with mild, moderate, or great complexity congenital heart disease. Acute success was 100%, with no complications and minimal recurrence over 48 months. This approach eliminates radiation exposure while maintaining safety and efficacy across select yet
