RF Heating of Bipolar Epicardial Implants during MRI at 0.55 T and 1.5T: Effect of Device Length and Termination Conditions

This study evaluates RF heating of bipolar epicardial leads during MRI at 0.55 T and 1.5 T, showing field strength and termination conditions affect heating patterns and safety.

Left Bundle Branch Area Pacing Preserves Mechanical Strain and Synchrony Compared to Right Ventricular Apical Pacing in an Acute Paired Preclinical Model

This study compares left bundle branch area pacing and right ventricular apical pacing in dogs, finding LBBA pacing better preserves myocardial strain and synchrony.

Effect of Lead Body and Helix Design Variables on Implantation Success, Insertion Depth, and Muscle Torque in Left Bundle Branch Area: Insights from An Ex-Vivo Porcine Model

This study evaluates how helix design and axial force affect insertion success and muscle torque in porcine septum pacing leads.

Development of a Customizable Pacing Protocol to Induce Persistent Atrial Fibrillation in Swine

This paper develops a wireless pacing system to induce persistent atrial fibrillation in swine, demonstrating its ability to adjust pacing frequencies remotely and safely.

Antitachycardia Pacing is More Effective When Delivered to the Left Bundle Branch Area Compared to the Right Ventricle in a Pre-clinical Model of Ischemic Ventricular Tachycardia

This study compares the efficacy of antitachycardia pacing delivered to the left bundle branch area versus the right ventricle in a preclinical model of ischemic ventricular tachycardia, finding higher success rates with LBBA pacing.

Successful Cardiac Resynchronization Therapy Reduces Negative Septal Work in Patient-Specific Models of Dyssynchronous Heart Failure

This study uses patient-specific models to show that CRT improves myocardial work efficiency and reverse remodeling in DHF by reducing negative work in early-activated regions.
