QT Interval Evaluation in Right Ventricular Pacing: Validation of a Novel Formula

Pacing and Clinical Electrophysiology, EarlyView.
Abstract Background QT interval measurement in the presence of right ventricular pacing (RVP) represents a clinical challenge. We therefore aimed to derive and validate a formula for QT estimation during RVP in a large cohort of pacemaker patients. Methods and Results We prospectively enrolled 100 patients in a derivation cohort and 487 in a validation

Cardiac resynchronization therapy: Femoral approach

Revista Portuguesa de Cardiologia, 2017
We describe the case of a 62-year-old female patient with bilateral subclavian vein occlusion, in whom a cardiac resynchronization system was implanted via a femoral vein.

Left Ventricular wall Thickness and Decrement Evoked Potentials in Ablation of Ischemic Ventricular Tachycardia

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Introduction Preprocedural imaging can improve the success rate of ventricular tachycardia (VT) ablation. Left ventricular wall thickness (LVWT) measured by cardiac computed tomography (CT) can be used to identify infarct regions. We sought to determine whether an association exists between left ventricular wall thickness (LVWT) as obtained ...

Left Bundle Branch Area Pacing Reverts Electromechanical Window Negativity to a Similar Extent as Biventricular Pacing

Pacing and Clinical Electrophysiology, EarlyView.
BiVP = biventricular pacing; CRT = cardiac resynchronization therapy; EMW = electromechanical window; LBBAP = left bundle branch area pacing; QAoC = Time interval from the onset of the QRS complex to the center of the aortic valve closure artifact; QT = QT interval measured by tangent method.

Extracardiac compression of the inferolateral branch of the coronary vein by the descending aorta in a patient with dilated cardiomyopathy

Journal of Arrhythmia, 2017
Extracardiac structures can cause distortion of cardiac anatomy particularly in patients presenting with a significantly dilated heart, and/or thoracic deformities.

Safety and Performance of INVICTA DF4 Ventricular Defibrillation Lead: Results From APOLLO Prospective Multicenter Study

Pacing and Clinical Electrophysiology, EarlyView.
Abstract Background Implantable cardioverter‐defibrillator (ICD) therapy relies on reliable right ventricular leads for pacing, sensing, and defibrillation. The INVICTA DF4 lead is an active‐fixation, quadripolar design intended to optimize implant workflow and long‐term safety and performance. Methods APOLLO was a prospective, multicenter, single‐arm,

The interventricular conduction delays guide best cardiac resynchronization therapy: A tailored-patient approach to perform a CRT through Conduction System Pacing

Indian Pacing and Electrophysiology Journal
Evaluation of conduction intervals to predict success of resynchronization in biventricular pacing(BiVP) or Conduction System Pacing(CSP) is not spread in clinical practice. A right ventricle-to-left ventricle intrinsic conduction interval (RVs–LVs) > 70

Mid-term feasibility and safety of downgrade procedure from defibrillator to pacemaker with cardiac resynchronization therapy

International Journal of Cardiology: Heart & Vasculature, 2019
Backgrounds: Some patients who undergo implantation of cardiac resynchronization therapy with defibrillator (CRT-D) survive long enough, thus requiring CRT-D battery replacement.

Leadless Pacemaker Implantation in High‐Risk Patients: Real‐World Outcomes From a Multicenter Israeli Registry

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Introduction Transvenous pacemakers are effective but carry significant short‐ and long‐term complications. Leadless pacemakers were developed to overcome these limitations, however, data in high‐risk patients ineligible for transvenous systems remain limited.

Cardiac Resynchronization Therapy: Who Benefits?

Annals of Global Health, 2014
Background: Cardiac resynchronization therapy (CRT) has been well established in multiple large trials to improve symptoms, hospitalizations, reverse remodeling, and mortality in well-selected patients with heart failure when used in addition to optimal ...
