Can Cardiac Conduction System Disease Be Prevented?

JAMA Internal Medicine, 2016
Cardiac conduction system disorders on the electrocardiogram (ECG) are common. Left bundle branch block (LBBB) is associated with adverse outcomes, and variants previously considerednormal, suchas rightbundlebranchblock (RBBB),1 left anterior fascicularblock,2orPR intervalprolongation,3may also portend morbidity andmortality. At present, no paradigm to

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

Conduction System Disease in Fetuses Evaluated for Irregular Cardiac Rhythm

Fetal Diagnosis and Therapy, 2006
<i>Objectives:</i> To determine the prevalence of 1st and 2nd degree AV block in fetuses with an irregular cardiac rhythm, and to summarize outcome of these pregnancies. <i>Background:</i> The diagnosis of irregular cardiac rhythm or ‘skipped beats’ includes isolated ectopy that resolves spontaneously.

Prevalence, Incidence, and Impact on Mortality of Conduction System Disease in Transthyretin Cardiac Amyloidosis

The American Journal of Cardiology, 2020
Transthyretin cardiac amyloidosis (ATTR-CA) is an increasingly recognized infiltrative cardiomyopathy in which conduction system disease is common. The aim of our study was to define the incidence and prevalence of high-grade atrioventricular (AV) block requiring pacemaker implantation in our quaternary referral center.

PRKAG2 cardiac syndrome: familial ventricular preexcitation, conduction system disease, and cardiac hypertrophy

Current Opinion in Cardiology, 2002
Genetic studies of families with inherited cardiac rhythm disturbances have established a molecular basis for ventricular arrhythmogenic disorders. Genes responsible for the long QT syndrome, Brugada syndrome, and polymorphic ventricular tachycardia have been identified.

Conduction system disease in cardiac amyloidosis

Trends in Cardiovascular Medicine
Cardiac amyloidosis (CA) has diverse and deleterious effects on the conductive system. Atrial fibrillation is by far the most common electrophysiological manifestation of CA and is associated with more mortality, morbidity, and hospitalizations. While AF increases the risk of thrombosis regardless of the CHA2DS2-VASc score, the risk of thromboembolism ...

Cardiac conduction system disease after transcatheter aortic valve replacement

American Heart Journal, 2012
Transcatheter aortic valve replacement (TAVR) is a rapidly-evolving technology for patients with severe, calcific aortic stenosis. Although these procedures lessen many of the risks and complications of open surgical aortic valve replacement, there remain challenges with TAVR including electrophysiologic complications.

Sodium channel kinetic changes that produce Brugada syndrome or progressive cardiac conduction system disease

American Journal of Physiology - Heart and Circulatory Physiology, 2007
Some mutations of the sodium channel gene NaV1.5 are multifunctional, causing combinations of LQTS, Brugada syndrome and progressive cardiac conduction system disease (PCCD). The combination of Brugada syndrome and PCCD is uncommon, although they both result from a reduction in the sodium current.

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.

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.
