Importance of left atrial function in patients with myocardial infarction.

open access: yes, 1983
Left atrial function was evaluated in patients with and without remote myocardial infarction. The simultaneous left atrial pressure recording and left atrial and left ventricular cineangiograms were obtained with a catheter-tip micromanometer.

Centrum Semiovale Perivascular Spaces Predict First Hemorrhagic Lesion in Asymptomatic Amyloid‐Positive Individuals

open access: yesAnnals of Neurology, EarlyView.
Objective Identification of cerebral amyloid angiopathy (CAA) before its hemorrhagic manifestations remains limited. We aimed to determine whether severe enlarged perivascular spaces in the centrum semiovale (EPVS‐CSO) identify a prehemorrhagic stage of sporadic CAA by predicting the first appearance of CAA‐related hemorrhagic lesions or incident ...

Left atrial vortex flow and its relationship with left atrial functions in patients with congenital heart disease

open access: yesThe Egyptian Heart Journal
Background Four-dimensional flow magnetic resonance imaging (MRI) enables blood flow visualization. The absence of left atrial vortex flow (LAVF) has been implicated in the development of thrombus formation and arrhythmias.

Cardiac morphological and morphometric analysis of Ardea alba

open access: yesThe Anatomical Record, EarlyView.
Abstract Ardea alba (Linnaeus, 1758) is a widely distributed heron species whose cardiovascular morphology remains poorly described. This study aimed to characterize the cardiac morphology and morphometry of adult A. alba. Ten specimens were analyzed using radiographic, morphometric, histological, scanning electron microscopy, and three‐dimensional ...

Left Atrium Volume Index Profile in Diastolic Dysfunction

open access: yesMajalah Kardiologi Indonesia, 2013
Background. Diastolic dysfunction is frequently found in hypertension,usually accompanied with left ventricular hypertrophy. Several parameter was developed to assess the diastolic function including left atrial volume index, E/A, DT, IVRT, S/D, E/e ...

SOX6 is expressed in various cell lineages in the developing mouse heart and contributes to proper valvuloseptal development

open access: yesThe Anatomical Record, EarlyView.
Abstract Cells derived from the endocardium, epicardium, cardiac neural crest, and second heart field play a critical role in the formation of the valvuloseptal structures of the heart. Previous studies have shown that the expression of the transcription factor SOX9 in these cell populations is essential in the regulation of this process.

Descriptive, stratigraphic, and morpho‐functional study of the myocardium and myocardial bridges in domestic pig hearts

open access: yesThe Anatomical Record, EarlyView.
Abstract The heart is the central organ of the cardiovascular system. The myocardium is composed of a three‐dimensional network of fibers arranged in clockwise and counterclockwise helices, which are essential for proper cardiac contraction. This study aimed to describe the stratigraphic and morpho‐functional pattern of the porcine myocardium to ...

The Clinical Applications of Left Atrial Strain: A Comprehensive Review

open access: yesMedicina
Left atrial (LA) strain imaging, which measures the deformation of the LA using speckle-tracing echocardiography (STE), has emerged recently as an exciting tool to help provide diagnostic and prognostic information for patients with a broad range of ...

Morphological variation of the conus arteriosus in Chondrichthyes: Implications for ecology and evolution

open access: yesThe Anatomical Record, EarlyView.
Abstract Cartilaginous fish have diverse morphological traits that are essential for understanding their evolutionary history and ecological adaptations. However, the conus arteriosus and its valves, key components of the heart and blood circulation, have been underexplored in phylogenetic and ecomorphological contexts.
