Case report: Challenges and implications of conduction system pacing in pediatrics: Case series

Frontiers in Pediatrics, 2023
Cardiac electrical stimulation in children usually is needed in the setting of complete congenital atrioventricular block, atrioventricular block after heart surgery, and bradycardia associated with some specific channelopathies.

Advances and Prospects in Understanding Vertebrate Cardiac Conduction System, Pacemaker Cell, and Cardiac Muscle Development: Toward Novel Biological Therapies

Muscles, 2023
The heart is composed of muscle cells called cardiomyocytes, including a specialized population named pacemaker cells that form the cardiac conduction system (CCS), which is responsible for generating the action potential dictating heart contractions ...

Emerging from the Darkness. Sudden Cardiac Death in Cardiac Amyloidosis

Reviews in Cardiovascular Medicine, 2022
Cardiac amyloidosis (CA) manifests as infiltrative cardiomyopathy with a hypertrophic pattern, usually presenting with heart failure with a preserved ejection fraction. In addition, degenerative valvular heart disease, particularly severe aortic stenosis,

Connexin diversity in the heart: insights from transgenic mouse models

Frontiers in Pharmacology, 2013
Cardiac conduction is mediated by gap junction channels that are formed by connexin (Cx) protein subunits. The connexin family of proteins consists of 24 members, varying in their biophysical properties and ability to combine with other connexins into ...

Surgical and Electrical Anatomy of the Inter-Nodal and Intra-Atrial Conduction System in the Heart

Journal of Chest Surgery, 2022
An anatomical understanding of the atrial myocardium is crucial for surgeons and interventionists who treat atrial arrhythmias. We reviewed the anatomy of the inter-nodal and intra-atrial conduction systems.

Anatomical considerations and emerging strategies for reducing new onset conduction disturbances in percutaneous structural heart disease interventions [PDF]

, 2021
Transcatheter procedures offer an alternative to cardiac surgery in select patients with structural heart disease (SHD). Unfortunately, inadvertent disruption of electrical pathways and subsequent development of new onset conduction disturbances can ...
