The Role of Left Atrial Strain in Detecting Left Ventricular Diastolic Dysfunction: Comparison between the 2009 and 2016 Recommendations

open access: yesJournal of Tehran University Heart Center, 2021
Background: The frequency of left ventricular diastolic dysfunction (DD) is overestimated by earlier recommendations. We compared the 2009 and 2016 guidelines regarding the detection of DD and explored the potential of adding left atrial (LA) strain to ...

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.

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 ...

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 ...

Physics-informed neural networks to learn cardiac fiber orientation from multiple electroanatomical maps [PDF]

open access: yes, 2022
We propose FiberNet, a method to estimate \emph{in-vivo} the cardiac fiber architecture of the human atria from multiple catheter recordings of the electrical activation. Cardiac fibers play a central role in the electro-mechanical function of the heart, yet they are difficult to determine in-vivo, and hence rarely truly patient-specific in existing ...

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 ...

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.

Pairwise-Constrained Implicit Functions for 3D Human Heart Modelling [PDF]

open access: yesarXiv, 2023
Accurate 3D models of the human heart require not only correct outer surfaces but also realistic inner structures, such as the ventricles, atria, and myocardial layers. Approaches relying on implicit surfaces, such as signed distance functions (SDFs), are primarily designed for single watertight surfaces, making them ill-suited for multi-layered ...

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 ...
