High-Grade Left Atrial Pleomorphic Sarcoma: Case Report and Review

open access: yesCase Reports in Oncology, 2017
Primary pleomorphic sarcoma of the left atrium is a rare tumor. There is no actual evidence of the management of this pathological entity, so the main treatment is individualized, surgical management being the cornerstone of the treatment.

Atrial fibrillation and electrophysiology in transgenic mice with cardiac-restricted overexpression of FKBP12 [PDF]

open access: yes, 2019
Cardiomyocyte-restricted overexpression of FK506-binding protein 12 transgenic (αMyHC-FKBP12) mice develop spontaneous atrial fibrillation (AF). The aim of the present study is to explore the mechanisms underlying the occurrence of AF in αMyHC-FKBP12 ...

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.

Morphological and Morphometric Study of Coronary Sinus in Human Cadaveric Hearts in Gujarat Region, India: A Cross-sectional Study [PDF]

open access: yesInternational Journal of Anatomy Radiology and Surgery, 2023
Introduction: The major vein draining blood from the heart is the Coronary Sinus (CS). Its significance in facilitating numerous cardiac treatments such as biventricular pacing, and the placement of a variety of cardiac devices has made the CS a ...

Effects of candesartan, an angiotensin II receptor type I blocker, on atrial remodeling in spontaneously hypertensive rats [PDF]

open access: yes, 2015
Hypertension-induced structural remodeling of the left atrium (LA) has been suggested to involve the renin–angiotensin system. This study investigated whether treatment with an angiotensin receptor blocker, candesartan, regresses atrial remodeling in ...

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 ...

Altered excitation-contraction coupling in human chronic atrial fibrillation [PDF]

open access: yes, 2012
This review focuses on the (mal)adaptive processes in atrial excitation-contraction coupling occurring in patients with chronic atrial fibrillation. Cellular remodeling includes shortening of the atrial action potential duration and effective refractory ...

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.

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.
