Attenuation of stretch-induced arrhythmias following chemical ablation of Purkinje fibres, in isolated rabbit hearts

Frontiers in Physiology, 2023
Purkinje fibres (PFs) play an important role in some ventricular arrhythmias and acute ventricular stretch can evoke mechanically-induced arrhythmias. We tested whether Purkinje fibres, play a role in these arrhythmias.

Efficacy of Fixed Low-Power Long-Duration Radiofrequency Ablation of Ventricular Arrhythmias Originating From the Left Ventricular Summit. [PDF]

J Arrhythm
Efficacy and safety of a fixed low‐power, long‐duration radiofrequency catheter ablation of ventricular arrhythmias originating from the left ventricular summit. ABSTRACT Background Radiofrequency catheter ablation (RFCA) of ventricular arrhythmias originating from the left ventricular summit (LVS‐VAs) remains challenging.

Hypoplastic Left Heart Syndrome: A New Paradigm for an Old Disease?

Journal of Cardiovascular Development and Disease, 2019
Hypoplastic left heart syndrome occurs in up to 3% of all infants born with congenital heart disease and is a leading cause of death in this population. Although there is strong evidence for a genetic component, a specific genetic cause is only known in ...

The effect of exercise training on left ventricular function in young elite athletes

Cardiovascular Ultrasound, 2011
Background Regular training, in particular endurance exercise, induces structural myocardial adaptation, so-called "athlete's heart". In addition to the 2D standard echo parameters, assessment of myocardial function is currently possible by deformation ...

Primary Cardiac Angiosarcoma in a Young Male: Rare Presentation With Right Atrial Endocardial Dissection and Right Coronary Artery Tumor Fistula. [PDF]

Clin Case Rep
ABSTRACT We report the case of a 19‐year‐old man who presented with several months of exertional dyspnea and recent‐onset hemostasis. Initial imaging revealed multiple pulmonary nodules. Days later, he was referred to a specialized center with chest pain and signs of pericarditis.

Tbx20 Induction Promotes Zebrafish Heart Regeneration by Inducing Cardiomyocyte Dedifferentiation and Endocardial Expansion

Frontiers in Cell and Developmental Biology, 2020
Heart regeneration requires replenishment of lost cardiomyocytes (CMs) and cells of the endocardial lining. However, the signaling regulation and transcriptional control of myocardial dedifferentiation and endocardial activation are incompletely ...

Outflow Tract Formation—Embryonic Origins of Conotruncal Congenital Heart Disease

Journal of Cardiovascular Development and Disease, 2021
Anomalies in the cardiac outflow tract (OFT) are among the most frequent congenital heart defects (CHDs). During embryogenesis, the cardiac OFT is a dynamic structure at the arterial pole of the heart.
