Conduction System Disease in Cardiac Amyloidosis.

Trends in Cardiovascular Medicine, 2023
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

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

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.

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 ...

Hereditary Long QT Syndrome Associated with Cardiac Conduction System Disease

Pacing and Clinical Electrophysiology, 1989
This report describes the cardiac conduction abnormalities, detected by invasive electrophysiological study, in two identical siblings with symptomatic congenital long QT syndrome. Both patients had evidence of intra‐Hisian conduction delay in response to programmed atrial stimulation and pacing induced infranodal block was seen in one of the two ...

Symptomatic conduction system disease in cardiac amyloidosis.

The American Journal of Cardiology, 1997
Symptomatic conduction system disease in cardiac amyloidosis and its management has been reported infrequently. We report our experience of patients with amyloidosis having symptomatic conduction system disease requiring permanent pacemaker implantation.

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.
