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.

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 ...

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 ...

Detection of C-type natriuretic peptide (CNP) transcript in the rat heart and immune organs [PDF]

open access: yes, 1993
Previous studies suggested the expression of mRNA, coding for CNP, exclusively in the central nervous system. In the present study, using the polymerase chain reaction (PCR) technique instead of the less sensitive Northern blot hybridization, CNP ...

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 ...

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 ...

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 ...

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.

Complete atrial-specific knockout of sodium-calcium exchange eliminates sinoatrial node pacemaker activity. [PDF]

open access: yes, 2013
The origin of sinoatrial node (SAN) pacemaker activity in the heart is controversial. The leading candidates are diastolic depolarization by "funny" current (If) through HCN4 channels (the "Membrane Clock" hypothesis), depolarization by cardiac Na-Ca ...
