Relationship Between Complex Signal Identification and Non‐Pulmonary Vein Foci

Journal of Arrhythmia, Volume 41, Issue 6, December 2025.
Using the CARTO CSI algorithm, electrogram fractionation (score ≥ 8.5) accurately localized non‐pulmonary vein triggers. CSI‐assisted ablation guided by these high‐complexity sites resulted in 82.4% arrhythmia‐free survival, demonstrating the feasibility of CSI as a selective mapping adjunct comparable to FAAM.

Incidence and In‐Hospital Outcomes of Bradycardia or Atrioventricular Conduction Disorder in Patients With Type 2 Myocardial Infarction: A Nationwide Inpatient Analysis

Journal of Arrhythmia, Volume 41, Issue 6, December 2025.
Bradycardia and AV conduction disorder occurred in 6% of patients with T2MI, comparable to those with type 1 MI. In patients with T2MI, bradycardia and AV conduction disorder, particularly third‐degree AV blocks, were independently associated with in‐hospital mortality and cardiogenic shock.

Familial sick sinus syndrome in two siblings

The Turkish Journal of Pediatrics, 1993
Two siblings with sinus node disease are presented. The patients were severely affected and required permanent pacing. A cardiac electrophysiologic study was conducted in Case 2, which revealed an atrioventricular conduction disturbance in ...

The Evolving Landscape of Immunotoxicity: Charting Mechanisms and Future Strategies for Immune Checkpoint Inhibitor Adverse Events

Med Research, Volume 1, Issue 3, Page 322-358, December 2025.
ABSTRACT The use of immune checkpoint inhibitors (ICIs) has significantly improved the efficacy of cancer therapy, but their associated immune‐related adverse events (irAEs) can severely compromise treatment safety. This review systematically summarizes the core mechanisms underlying irAEs, which include multi‐organ damage resulting from T‐cell ...

Cardiac Angiosarcoma With Lung Metastasis Presenting as Granuloma‐Like Lesions: One Case Report and Literature Review

Respirology Case Reports, Volume 13, Issue 12, December 2025.
In this report, we present a case of a 30‐year‐old female who initially presented with recurrent hemoptysis and multiple pulmonary nodules with exudative changes in the lung, pathologically resembling granulomatous lesions and eventually confirmed as primary cardiac angiosarcoma with pulmonary metastasis.

Isorhythmic atrioventricular dissociation during anaesthesia in a cat

Veterinary Record Case Reports, Volume 13, Issue 4, December 2025.
Abstract A 10‐year‐old, male, neutered domestic shorthair cat with suspected hypertrophic cardiomyopathy was referred for cystotomy to remove uroliths present in its urinary bladder. Fifteen minutes after induction of general anaesthesia, atrioventricular dissociation was noted on the electrocardiogram with similar atrial and ventricular firing rates ...

Aged Zebrafish as a Spontaneous Model of Cardiac Valvular Disease

Aging Cell, Volume 24, Issue 12, December 2025.
Natural ageing in zebrafish results in spontaneous development of valvular degeneration in both the atrioventricular (AV) and bulboventricular (BV) valves. Aged zebrafish valves are larger and exhibit cystic regions, immune cell infiltration, early osteoblast differentiation and increased regurgitation.
