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

Journal 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 ...

Profibrotic, Electrical, and Calcium-Handling Remodeling of the Atria in Heart Failure Patients With and Without Atrial Fibrillation

Frontiers in Physiology, 2018
Atrial fibrillation (AF) and heart failure (HF) are common cardiovascular diseases that often co-exist. Animal models have suggested complex AF-promoting atrial structural, electrical, and Ca2+-handling remodeling in the setting of HF, but data in human ...

Topographical mapping of catecholaminergic axon innervation in the flat-mounts of the mouse atria: a quantitative analysis

Scientific Reports, 2023
The sympathetic nervous system is crucial for controlling multiple cardiac functions. However, a comprehensive, detailed neuroanatomical map of the sympathetic innervation of the heart is unavailable.

The Role of Lyophilized Xenodermotransplants in Repairing the Atria’s Structure and the Peculiarities of Regenerative Processes after Thermal Trauma in an Experiment

Life, 2023
The effects of severe burn injuries on the cardiovascular system, specifically the atria and auricles of the heart, were investigated. The potential benefits of using lyophilized xenodermotransplants as a treatment option were also evaluated.

Adenosine-Induced Atrial Fibrillation: Localized Reentrant Drivers in Lateral Right Atria due to Heterogeneous Expression of Adenosine A1 Receptors and GIRK4 Subunits in the Human Heart

Circulation, 2016
Background Adenosine provokes atrial fibrillation (AF) with a higher activation frequency in right atria (RA) versus left atria (LA) in patients, but the underlying molecular and functional substrates are unclear.

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

Case 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.

Application of an automatic segmentation method for evaluating cardiac structure doses received by breast radiotherapy patients

Physics and Imaging in Radiation Oncology, 2021
Background and purpose: Quantifying radiation dose to cardiac substructures is important for research on the etiology and prevention of complications following radiotherapy; however, segmentation of substructures is challenging.
