First Pediatric Application of Bachmann's Bundle Pacing and Left Bundle Branch Area Pacing for Bi‐Physiologic Conduction System Pacing

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Atrial pacing at right atrial appendage causes nonphysiologic delays. Bachmann's bundle (BB) pacing preserves synchrony but lacks pediatric data. Case Summary We report the first pediatric combined BB and left bundle branch area pacing in a 9‐year‐old boy (23.5 kg).

Usefulness of electroanatomical mapping during transseptal endocardial left ventricular lead implantation [PDF]

, 2015
AimFailure rate to implant left ventricular (LV) lead transvenously is 4-8% in cardiac resynchronization therapy (CRT) patients. Epicardial lead placement is an alternative method and if not applicable case reports and small series showed the ...

Surface ECG interatrial block-guided treatment for stroke prevention: rationale for an attractive hypothesis

BMC Cardiovascular Disorders, 2017
Atrial fibrillation (AF) is the most common sustained arrhythmia and is associated with stroke, cognitive impairment, and cardiovascular death. Some predisposing factors − as aging, diabetes, hypertension − induce and maintain electrophysiological and ...

Mechanisms underlying local Ca2+ signalling differences between right and left atrial myocytes at normal and increased frequencies

The Journal of Physiology, EarlyView.
Abstract figure legend Left atrial myocytes have TAT‐associated faster Ca2+ release but are more prone to maladaptation at higher frequencies due to weaker peripheral SR Ca2+ uptake and smaller trigger Ca2+ current. Abstract Changes in heart rate affect Ca2+ signalling and contractility in ventricular muscle, but the effects on atrial Ca2+ signalling ...

Isolated right ventricular infarction: a diagnostic challenge [PDF]

, 2016
A 73-year-old woman was admitted to the emergency room due to sudden-onset dyspnoea, altered mental status and haemodynamic instability. ECG showed a junctional rhythm, T-wave inversion in I, aVL and V2-V6 (present in a previous ECG), and no ST/T changes

Horizontal Heart Orientation as a Mechanistic Contributor to Platypnea–Orthodeoxia Syndrome in Patent Foramen Ovale

Clinical Case Reports, Volume 14, Issue 5, May 2026.
ABSTRACT Altered cardiac orientation in the presence of a patent foramen ovale (PFO) can contribute to platypnea–orthodeoxia syndrome (POS) and unexplained hypoxemia. In such cases, consideration of PFO closure may lead to significant clinical improvement.

Pulsed Field Ablation for Atrial Fibrillation in Patients With Obesity: Procedural and Clinical Outcomes

Pacing and Clinical Electrophysiology, Volume 49, Issue 5, Page 636-643, May 2026.
ABSTRACT Background Procedural and clinical outcomes in patients with obesity undergoing catheter ablation for atrial fibrillation (AF) have been mixed. Clinical data in the context of pulsed field ablation (PFA) are currently limited in this patient cohort.

Atrial Fibrillation Dynamics and Ionic Block Effects in Six Heterogeneous Human 3D Virtual Atria with Distinct Repolarization Dynamics

Frontiers in Bioengineering and Biotechnology, 2017
Atrial fibrillation (AF) usually manifests as reentrant circuits propagating through the whole atria creating chaotic activation patterns. Little is yet known about how differences in electrophysiological and ionic properties between patients modulate ...

Adipocytes in Aortic Stenosis: Association With Clinical and Morphological Indices

Clinical Anatomy, Volume 39, Issue 3, Page 325-331, April 2026.
ABSTRACT Recently, great attention has been given to understanding the new pathogenetic mechanisms underlying aortic stenosis (AS). The study aims to understand the role of mature adipocytes in AS and their association with histologic, clinical, and echocardiographic data, an area previously overlooked in AS research.
