Novel Observations on the Precursor Arrhythmias of Ventricular Fibrillation in the Ambulatory Setting

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction Ventricular fibrillation (VF) is a lethal arrhythmia documented on outpatient telemetry monitoring. Ambulatory ECG in arrhythmic sudden death has shown VF as the terminal arrhythmia in about 80% of cases. Studies of VF in the ambulatory setting are sparse but suggest VF is commonly preceded by monomorphic ventricular tachycardia ...

The disease mutation A77V in Ryanodine receptor RyR2 induces changes in energy conduction pathways in the protein [PDF]

, 2011
Energetically responsive residues of the 217 amino acid N-terminal domain of the cardiac Ryanodine receptor RyR2 are identified by a simple elastic net model. These residues lie along a hydrogen bonded path through the protein.

Impact of Dental Status on Heart Transplantation Outcomes

Oral Diseases, EarlyView.
ABSTRACT Objective Oral infections and poor dental health may contribute to systemic complications after heart transplantation, yet data on their impact is limited. In the absence of standardized dental guidelines for transplant candidates, this study evaluated preoperative dental status and its association with post‐transplant outcomes.

Impact of Exercise Restriction on Arrhythmic Risk Among Patients With Arrhythmogenic Right Ventricular Cardiomyopathy

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
Background Prior studies have shown a close link between exercise and development of arrhythmogenic right ventricular cardiomyopathy. How much exercise restriction reduces ventricular arrhythmia (VA), how genotype modifies its benefit, and whether it ...

Fatty images of the heart: spectrum of normal and pathological findings at computed tomography and cardiac magnetic resonance imaging. [PDF]

, 2018
Ectopic cardiac fatty images are not rarely detected incidentally at computed tomography and cardiac magnetic resonance, either in exams focused on the heart as in general thoracic imaging evaluations.

Arrhythmogenic right ventricular cardiomyopathy [PDF]

Journal of Arrhythmia, 2018
AbstractArrhythmogenic right ventricular cardiomyopathy (ARVC) is a progressive cardiomyopathy characterized by fibrofatty infiltration of the myocardium, ventricular arrhythmias, sudden death, and heart failure. ARVC may be an important cause of syncope, sudden death, ventricular arrhythmias, and/or wall motion abnormalities, especially in the young ...

Pathogenesis of Arrhythmogenic Cardiomyopathy [PDF]

Canadian Journal of Cardiology, 2015
Arrhythmogenic cardiomyopathy (ACM) is a primary myocardial disease. It is characterized by frequent ventricular arrhythmias and increased risk of sudden cardiac death typically arising as an early manifestation before the onset of significant myocardial remodelling.

Left Ventricular wall Thickness and Decrement Evoked Potentials in Ablation of Ischemic Ventricular Tachycardia

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Introduction Preprocedural imaging can improve the success rate of ventricular tachycardia (VT) ablation. Left ventricular wall thickness (LVWT) measured by cardiac computed tomography (CT) can be used to identify infarct regions. We sought to determine whether an association exists between left ventricular wall thickness (LVWT) as obtained ...

Arrhythmogenic Right Ventricular Cardiomyopathy and Cor Triatriatum Dexter: An Unreported Association

Clinical Case Reports
We present a 74‐year‐old patient with a previous diagnosis of arrhythmogenic right ventricular cardiomyopathy manifesting as heart failure where a concomitant cor triatriatum dexter has accidentally been diagnosed by echocardiography.

Treatment of arrhythmogenic right ventricular cardiomyopathy (dysplasia) [PDF]

Кардіохірургія та інтервенційна кардіологія, 2016
Arrhythmogenic right ventricular cardiomyopathy (dysplasia) is an inheritable heart muscle disease predisposing to ventricular arrhythmias and increasing risk of sudden cardiac death.
