Hypertrophic Cardiomyopathy and Symptomatic Conduction System Disease in Cardiac Amyloidosis

Southern Medical Journal, 2006
Cardiac involvement is the most important prognostic factor in primary amyloidosis (AL). The clinical presentation of amyloid cardiomyopathy is varied and may manifest as heart failure, brady or tachyarrhythmias, syncope, angina and rarely with features of hypertrophic cardiomyopathy and advanced symptomatic conduction system disease. The management of

Electrophysiologic effects of intravenous magnesium in patients with normal conduction systems and no clinical evidence of significant cardiac disease

American Heart Journal, 1988
Parenteral magnesium has been used for several decades in the empiric treatment of various arrhythmias, but the data on its electrophysiologic effects in man are limited. We evaluated the electrophysiologic effects of magnesium sulfate (MgSO4) administration in eight normomagnesemic patients with normal mononuclear cell magnesium content, who had no ...

Cardiac transthyretin amyloidosis in patients with conduction system disease

European Heart Journal
Abstract Background/Introduction Cardiac amyloidosis (CA) is characterized by extracellular deposition of misfolded proteins in the heart. The data suggest that cardiac amyloidosis is underappreciated as a cause of common cardiac diseases or syndromes.

Postmortem Studies of the Intertruncal Plexus and Cardiac Conduction System From Patients With Chagas Disease Who Died Suddenly☆

Progress in Cardiovascular Diseases, 2005
Throughout the cardiac conduction system of each heart there were numerous destructive lesions including focal inflammatory infiltration with lymphocytes and in neighboring regions extensive focal fibrotic degeneration. These lesions involved myocytes, nerves and blood vessels.

[Steinert's disease with cardiac arrhythmia. Morphological findings in the heart conduction system].

Archivos del Instituto de Cardiologia de Mexico, 1975
This is a case report of a 63-year-old man with myotonic dystrophy in whom an ECG showed atrial flutter, complete A-V block, idioventricular rhythm with image of left bundle branch block and giant, wide and negative "T-U" waves. The microscopic study of the conduction system showed slight fibrosis of the SAN, fatty infiltration and cellular atrophy of ...

Conduction system disease management in patients candidate and/or treated for the aortic valve disease: an Italian Survey promoted by Italian Association of Arrhythmology and Cardiac Pacing (AIAC)

Acta Cardiologica
Conduction system disorders represent a frequent complication in patients undergoing surgical (surgical aortic valve replacement, SAVR) or percutaneous (transcatheter aortic valve implantation, TAVI) aortic valve replacement. The purpose of this survey was to evaluate experienced operators approach in this clinical condition.This survey was ...

In silico experiments explain the non‐consistent benefit of conduction system pacing over cardiac resynchronization therapy. The need to personalize therapy

Cardiovascular Electrophysiology, 2023
The study by Strocchi et al. adds evidence that choosing the cardiac resynchronization therapy (CRT) according to the cardiac substrate of each patient could be beneficial.

Abstract P1144: Single-cell RNA-Sequencing Of The Murine Cardiac Conduction System Reveals Transcriptional Regulators Associated With Conduction Development And Disease

Circulation Research, 2023
Rhythmic beating of the heart is driven by a small subset of heart cells, altogether known as the cardiac conduction system (CCS). The CCS consists of unique components including the sinoatrial node (SAN), the atrioventricular node (AVN), the bundle of His, bundle branches and Purkinje fiber (PF) system.
