Impact of Pericardial Fat on Intracardiac Atrial Impedance and Generator Impedance

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
Intracardiac atrial impedance (IAI) was associated with pericardial fat volume, serum sodium levels, and hemoglobin concentrations, but not with body mass index. IAI was also an independent determinant of generator impedance. These findings suggest that IAI may serve as a real‐time indicator for optimizing ablation strategies based on patient‐specific ...

Absent Left Main Coronary Artery with Separate Origin of Left Anterior Descending Artery and Left Circumflex Artery from Left Coronary Sinus

Methodist DeBakey Cardiovascular Journal
We report a case of a 49-year-old female who presented with atypical chest pain. An electrocardiogram-gated coronary computed tomography angiography revealed the absence of the left main coronary artery segment with direct origin of the left anterior ...

Electrophysiological Characteristics of Atrial Fibrillation Trigger Sites During Ongoing Atrial Fibrillation Using Ultra‐High‐Resolution Mapping

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
AF trigger sites exhibited a markedly shorter minimum local cycle length during ongoing AF, suggesting transient rapid activity. Ultra‐high‐resolution mapping during ongoing AF may provide complementary mechanistic information when conventional trigger mapping is inconclusive.

Atrial Leadless Pacemaker Embolization to the Left Common Iliac Vein With Successful Retrieval: A Case Report

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
A rare extracardiac complication in which a dislodged atrial leadless pacemaker migrated retrogradely to the left common iliac vein. This case highlights the role of venous anatomy in implantation difficulty and demonstrates successful device retrieval using a preventive strategy.

Zero Fluoroscopy Radiofrequency Slow‐Pathway Modification for AVNRT in Patients ≤ 21 Years: A Single‐Center Cohort and Contextual Review of Literature

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
In 125 consecutive pediatric and young adult patients (age ≤ 21 years), zero‐fluoroscopy radiofrequency slow‐pathway modification for AVNRT—guided entirely by CARTO 3D electroanatomic mapping—achieved 100% acute success, zero recurrences at 36‐month follow‐up, and zero major complications, supporting fluoroless RF ablation as a durable first‐line ...

Echocardiographic detection of intimo-intimal intussusception in a patient with acute Stanford type A aortic dissection

Annals of Cardiac Anaesthesia, 2015
Intimo-intimal intussusception is a very rare and unusual complication of type A dissections, typically noted on  TEE exam. It has been reported in a few cases in the cardiothoracic surgical and radiology literature, and even more rarely in the cardiac ...
