The right ventricle in congenital heart disease [PDF]
Heart, 2006 In patients with congenital heart disease the right ventricle (RV) may support the pulmonary (subpulmonary RV) or the systemic circulation (systemic RV). During the last 50 years evidence is accumulating that RV dysfunction develops in many of these patients and leads to considerable morbidity and mortality.

PDE2 activity differs in right and left rat ventricular myocardium and differentially regulates β2 adrenoceptor-mediated effects [PDF]
, 2015 The important regulator of cardiac function, cAMP, is hydrolyzed by different cyclic nucleotide phosphodiesterases (PDEs), whose expression and activity are not uniform throughout the heart. Of these enzymes, PDE2 shapes β1 adrenoceptor-dependent cardiac

α1-adrenergic stimulation increases ventricular action potential duration in the intact mouse heart
FACETS, 2021 The role of α1-adrenergic receptors (α-ARs) in the regulation of myocardial function is less well-understood than that of β-ARs. Previous reports in the mouse heart have described that α1-adrenergic stimulation shortens action potential duration in ...

Persistent ventricle partitioning in the adult zebrafish heart [PDF]
Journal of Cardiovascular Development and Disease, 2021 Abstract The vertebrate heart integrates cells from the early-differentiating first heart field (FHF) and the later-differentiating second heart field (SHF) emerging from the lateral plate mesoderm. In mammals, this process forms the basis for the development of the left and right ventricle chambers and subsequent ...

A heart within the heart: double-chambered left ventricle [PDF]
European Heart Journal - Cardiovascular Imaging, 2008 We describe a rare congenital anomaly in a 49-year-old woman who presented with palpitations and slightly reduced exercise capacity. A double-chambered left ventricle was suspected on echocardiography and confirmed by cardiac computed tomography scanning, cardiac magnet resonance imaging, and invasive angiography.

Histological study on the heart ventricle of Egyptian bovines (Bos aegyptiacus) [PDF]
Open Veterinary Journal, 2019 Background: The heart ventricles have thicker walls than atrium as they pump blood through blood vessels into all body organs. Aim: This study aimed to describe the histological changes of the heart ventricles in Egyptian bovine (Bos aegyptiacus) with ...
