Cor triloculares biatritum with tricuspid atresia in an african child

open access: yesHeart India, 2014
Cor triloculares biatritum is a rare congenital heart disease characterized by a three-chambered heart consisting of two atria and a single ventricle; however the case of a 5-month-old African boy who in addition to this defect had an associated ...

Accurate Detection of Septal Defects With Fetal Ultrasonography Images Using Deep Learning-Based Multiclass Instance Segmentation

open access: yesIEEE Access, 2020
Accurate screening for septal defects is important for supporting radiologists' interpretative work. Some previous studies have proposed semantic segmentation and object detection approaches to carry out fetal heart detection; unfortunately, the models ...

A neonate with ‘amphibian heart’: A rare combination of complex congenital heart diseases

open access: yesIHJ Cardiovascular Case Reports, 2021
Persistent truncus arteriosus is a rare congenital malformation of the heart. It arises from the ventricular cavity through a common ventriculo-arterial junction and is usually associated with doubly committed ventricular septal defect.

Haemogenic endocardium contributes to transient definitive haematopoiesis. [PDF]

open access: yes, 2013
Haematopoietic cells arise from spatiotemporally restricted domains in the developing embryo. Although studies of non-mammalian animal and in vitro embryonic stem cell models suggest a close relationship among cardiac, endocardial and haematopoietic ...

Anti-adrenergic effects of endothelin on human atrial action potentials are potentially anti-arrhythmic [PDF]

open access: yes, 2006
Endothelin-1 (ET-1) is elevated in patients with atrial fibrillation (AF) and heart failure. We investigated effects of ET-1 on human atrial cellular electrophysiological measurements expected to influence the genesis and maintenance of AF.

Three‐dimensional Integrated Functional, Structural, and Computational Mapping to Define the Structural “Fingerprints” of Heart‐Specific Atrial Fibrillation Drivers in Human Heart Ex Vivo

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
BackgroundStructural remodeling of human atria plays a key role in sustaining atrial fibrillation (AF), but insufficient quantitative analysis of human atrial structure impedes the treatment of AF.

Whole-Heart Assessment of Turbulent Kinetic Energy in the Repaired Tetralogy of Fallot

open access: yesApplied Sciences, 2022
Approximately 10% of congenital heart diseases (CHDs) include Tetralogy of Fallot (TOF). Fortunately, due to advanced surgical techniques, most patients survive until adulthood.

Electrophysiological effects of 5-hydroxytryptamine on isolated human atrial myocytes, and the influence of chronic beta-adrenoceptor blockade [PDF]

open access: yes, 2003
<b>1.</b> 5-Hydroxytryptamine (5-HT) has been postulated to play a proarrhythmic role in the human atria via stimulation of 5-HT<sub>4</sub> receptors.

Peculiarities of macro- and cytometric assessment of morphological structures of the domestic pig heart

open access: yesRegulatory Mechanisms in Biosystems
The cardiovascular system, which includes the heart, is one of the essential systems of the human and animal body. With its participation, the blood supply of the organs takes place; it promotes the outflow of lymph from the organs and its transport into

The early stages of heart development: insights from chicken embryos [PDF]

open access: yes, 2016
The heart is the first functioning organ in the developing embryo and the detailed understanding of the molecular and cellular mechanisms involved in its formation provides insights into congenital malformations affecting its function and therefore the ...
