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.

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 ...

The role of inhibitory G proteins and regulators of G protein signaling in the in vivo control of heart rate and predisposition to cardiac arrhythmias [PDF]

open access: yes, 2012
Inhibitory heterotrimeric G proteins and the control of heart rate. The activation of cell signaling pathways involving inhibitory heterotrimeric G proteins acts to slow the heart rate via modulation of ion channels.

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.

Transcription of brain natriuretic peptide and atrial natriuretic peptide genes in human tissues [PDF]

open access: yes, 1994
We have compared the expression of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) genes in various human tissues using a quantitative polymerase chain reaction technique.

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

A Case of Coumadin Ridge Confirmed by Surgery: Comparison between Cardiac Computed Tomographic Images and Operative Findings

open access: yes대한영상의학회지, 2019
The coumadin ridge, a ridge of atrial tissue separating the left atrial appendage from the left upper pulmonary vein, is considered to be a normal anatomic variant. A prominent coumadin ridge can be easily mistaken for a tumor or thrombus.

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.

Cardiac stem cells: A promising treatment option for heart failure. [PDF]

open access: yes, 2012
Cardiovascular diseases are the most common cause of death in the world. The development of heart failure is mainly due to the loss of cardiomyocytes following myocardial infarction and the absence of endogenous myocardial repair.
