Safety and Feasibility of a CT‐Based Pathway for Left Atrial Appendage Assessment Prior to Inpatient Cardioversion: A Single‐Center Experience

Clinical Cardiology, Volume 49, Issue 5, May 2026.
An alternative for TEE? Cardiac CT is a practical alternative for ruling out LA/LAA thrombi in hospitalized patients who need cardioversion. ABSTRACT Background Transesophageal echocardiography (TEE) for left atrial appendage (LAA) thrombus exclusion before cardioversion faces logistical barriers including limited availability, patient intolerance, and

Diagnosis and Management of Left Atrium Appendage Thrombosis in Atrial Fibrillation Patients Undergoing Cardioversion

Medicina, 2019
Atrial fibrillation is the most common cardiac arrhythmia and is associated with an increased risk of stroke and thromboembolic complications. A rhythm control strategy with both electrical and pharmacological cardioversion is recommended for patients ...

Possible Deslanoside‐Induced Left Posterior Fascicular Ventricular Tachycardia: A Case Report

Annals of Noninvasive Electrocardiology, Volume 31, Issue 3, May 2026.
A 73‐year‐old man with paroxysmal AF and no structural heart disease who developed left posterior fascicular ventricular tachycardia (LPFVT) shortly after intravenous Deslanoside administration for rate control. Highlights: cardiac glycosides, though effective for rate control, may occasionally precipitate Purkinje‐related ventricular tachycardia ...

Prehospital Risk Stratification Using Unsupervised Machine Learning in STEMI

European Journal of Clinical Investigation, Volume 56, Issue 5, May 2026.
Machine learning identified three phenotypes with 30‐day mortality of 3.4%, 22.1%, and 75%. Phenotype‐2 reveals an "occult high‐risk" group: hemodynamically stable yet six‐fold higher mortality. ABSTRACT Background ST‐elevation myocardial infarction (STEMI) exhibits substantial clinical heterogeneity complicating prehospital risk stratification ...

Left atrial size after cardioversion for atrial fibrillation: effect of external DC shock [PDF]

, 2003
OBJECTIVE: The aim of this study was to evaluate the effect of external direct current (DC) shock on left atrial (LA) dimension and volumes after cardioversion for atrial fibrillation, and the relation between LA size and atrial function.

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.

Smart Optogenetics for Real‐Time Automated Control of Cardiac Electrical Activity

Advanced Science, Volume 13, Issue 20, 9 April 2026.
We are able to stop dangerous heart‐rhythm spirals before they fully form. Within about 100 ms, it pinpoints the spiral's tiny central tip (≈0.9 mm) using light‐based sensing and machine learning, then shines targeted light to shut it down. This fast, precise, closed‐loop approach detects, targets, and terminates arrhythmias in real time.
