Atrioventricular Node Slow‐Pathway Ablation Reduces Atrial Fibrillation Inducibility: A Neuronal Mechanism

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundRadiofrequency ablation (RFA) for atrioventricular nodal reentrant tachycardia appears to reduce atrial tachycardia, which might relate to parasympathetic denervation at cardiac ganglionated plexuses.

Descriptive, stratigraphic, and morpho‐functional study of the myocardium and myocardial bridges in domestic pig hearts

The Anatomical Record, EarlyView.
Abstract The heart is the central organ of the cardiovascular system. The myocardium is composed of a three‐dimensional network of fibers arranged in clockwise and counterclockwise helices, which are essential for proper cardiac contraction. This study aimed to describe the stratigraphic and morpho‐functional pattern of the porcine myocardium to ...

Clinical Anatomy of the Left and Right Atrial Appendages in Humans: Comparative and Developmental Perspective

Clinical Anatomy, EarlyView.
ABSTRACT Human atrial chambers derive from distinct embryonic anlagens, the original embryonic atria gradually transforming into the so‐called auricles, or atrial appendages. This study quantifies macroscopic variations in pectinate muscle architecture in human atrial appendages and evaluates their visualization using clinical imaging modalities.

Pathophysiology of Cav1.3 L-type calcium channels in the heart

Frontiers in Physiology, 2023
Ca2+ plays a crucial role in excitation-contraction coupling in cardiac myocytes. Dysfunctional Ca2+ regulation alters the force of contraction and causes cardiac arrhythmias. Ca2+ entry into cardiomyocytes is mediated mainly through L-type Ca2+ channels,

Quo Vadis in Anatomical Research? Preserving the Conditions for Discovery in an Era of Predictable Outcomes

Clinical Anatomy, EarlyView.
ABSTRACT Contemporary anatomical research has become increasingly integrated with clinical practice, generating substantial benefits for patient care and strengthening the translational relevance of the discipline. At the same time, some of the most influential anatomical advances have emerged from investigations whose eventual significance could not ...

A case of typical atrioventricular nodal (AVN) reentrant tachycardia confined to the compact AV node, showing a variety of rare electrophysiological findings, including eccentric AVN echoes

Journal of Arrhythmia, 2014
Herein, we report the case of a 49-year-old woman with typical atrioventricular nodal (AVN) reentrant tachycardia, confined to the compact atrioventricular node, showing numerous rare electrophysiological findings such as unique AVN reentrant echoes ...

Repeated misclassifications of tachycardia by an implantable cardiac defibrillator

Indian Pacing and Electrophysiology Journal, 2020
This case describes repeated misclassifications of SVT due to AV node reentry as VT by an ICD. This case illustrates the limitations of SVT-VT discrimination algorithm.

Coronary Perforation During Excimer Laser Angioplasty in a Patient With Prior Thoracic Radiotherapy

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Management of heavily calcified coronary lesions remains challenging despite advances in plaque‐modifying technologies. Excimer laser coronary angioplasty (ELCA) is an effective adjunctive strategy with a low risk of no‐reflow. Case Summary A 75‐year‐old woman with non–ST‐segment elevation acute coronary syndrome and severe left ...

Transthyretin amyloid cardiomyopathy: Literature review and red‐flag symptom clusters for each cardiology specialty

ESC Heart Failure, Volume 12, Issue 2, Page 955-967, April 2025.
Abstract Wild‐type transthyretin amyloid cardiomyopathy (ATTRwt‐CM) is a progressive and infiltrative cardiac disorder that may cause fatal consequences if left untreated. The estimated survival time from diagnosis is approximately 3–6 years. Because of the non‐specificity of initial symptom manifestation and insufficient awareness among treating ...
