Transthoracic three-dimensional echocardiography for the assessment of straddling tricuspid or mitral valves [PDF]

, 2000
Background The advent of 3D echocardiography has provided a technique which, potentially, could afford significant additional information over conventional cross-sectional echocardiography in the assessment of patients with straddling atrioventricular ...

Cardiac morphological and morphometric analysis of Ardea alba

The 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 ...

At the Atrioventricular Crossroads: Dual Pathway Electrophysiology in the Atrioventricular Node and its Underlying Heterogeneities.

Arrhythmia & Electrophysiology Review, 2017
The atrioventricular node (AVN) is a complex structure that performs a variety of functions in the heart. The AVN is primarily an electrical gatekeeper between the atria and ventricles and introduces a delay between atrial and ventricular excitation ...

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

The 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.

Prenatal diagnosis of isolated atrioventricular discordance using fetal echocardiography [PDF]

, 2014
A 28-year-old female was referred to our institute at 25 weeks of gestation due to fetal bradycardia. Fetal echocardiography showed the stomach bubble was on the left side with the heart axis pointing to the left.

Identification of major congenital malformations based on healthcare databases in France: A proof‐of‐concept study using the epi‐meres nationwide mother–child register

British Journal of Clinical Pharmacology, EarlyView.
Abstract Aim Besides registries, healthcare databases can provide useful information for assessing the frequency of major congenital malformations (MCMs) and investigating their risk factors, particularly medication exposures. This study aimed to assess the validity of MCMs identification based on French national, comprehensive healthcare databases ...

Atrioventricular conduction abnormalities and atrioventricular blocks: role of electrophysiology testing [PDF]

, 2018
In sinus bradycardia, the role of electrophysiology studies is not established. A marked prolongation of the corrected sinus node recovery time (>800 ms) is a highly predictive but insensitive sign for sick sinus syndrome.
