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

Evolution of Human Scar-Related Ventricular Tachycardia Mapping for Exploring Mechanisms of Reentry Circuits

Reviews in Cardiovascular Medicine
Ventricular tachycardia (VT) can originate from diseased myocardium resulting from ischemic or nonischemic cardiomyopathy. Scar-related VT is predominantly sustained by reentrant circuits within areas of myocardial scar.

Function and dysfunction of human sinoatrial node [PDF]

, 2015
Sinoatrial node (SAN) automaticity is jointly regulated by a voltage (cyclic activation and deactivation of membrane ion channels) and Ca(2+) clocks (rhythmic spontaneous sarcoplasmic reticulum Ca(2+) release).

Comparative Outcomes of ICE Versus TEE/Fluoroscopy Guidance Transseptal Puncture in LA Procedures: A Systematic Review and Meta‐Analysis

Annals of Noninvasive Electrocardiology, Volume 31, Issue 3, May 2026.
ICE‐guided transseptal puncture reduces radiation exposure without compromising efficacy or safety, supporting its adoption as a valuable imaging modality in left atrial interventions. ABSTRACT Objective To evaluate the comparative efficacy, safety, and radiation exposure outcomes of intracardiac echocardiography (ICE)‐guided versus TEE/fluoroscopy ...

Myocardial and Neural Damage due to Pulmonary Vein Isolation: Comparison of Pulsed Electric Field and Thermal Ablation

Pacing and Clinical Electrophysiology, Volume 49, Issue 5, Page 618-625, May 2026.
ABSTRACT Background Pulmonary vein isolation (PVI) using thermal energy—radiofrequency (RF) or cryoablation (CRYO)—is associated with direct myocardial injury and collateral neural damage. In contrast, pulsed electric field (PEF) energy has emerged as a neural‐sparing alternative.

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.

Catheter Ablation of Ventricular Tachycardia Originating from the Left Posterior Papillary Muscle Guided by the Shadow of a Multipolar Catheter

Indian Pacing and Electrophysiology Journal, 2012
A 62-year-old man without structural heart disease underwent electrophysiological testing for ventricular tachycardia (VT). Hemodynamically unstable VT was induced after isoproterenol (ISP) provocation.

Human Embryonic Stem Cell-Derived Cardiomyocytes Regenerate the Infarcted Pig Heart but Induce Ventricular Tachyarrhythmias

Stem Cell Reports, 2019
Summary: Human embryonic stem cell-derived cardiomyocytes (hESC-CMs) show considerable promise for regenerating injured hearts, and we therefore tested their capacity to stably engraft in a translationally relevant preclinical model, the infarcted pig ...
