Clinical Anatomy of the Left and Right Atrial Appendages in Humans: Comparative and Developmental Perspective

Clinical Anatomy, EarlyView.
ABSTRACT Human atrial chambers derive from distinct embryonic anlagens, the original embryonic atria gradually transforming into the so‐called auricles, or atrial appendages. This study quantifies macroscopic variations in pectinate muscle architecture in human atrial appendages and evaluates their visualization using clinical imaging modalities.

Correlation of Electrocardiography with Echocardiography in the Assessment of Left Atrial Overload

Advanced Medical Journal
Background and objectives: Left atrial overload parameters in the electrocardiogram could suggest rising left atrial pressure that leads to heart disease. An increase in the Left atrial area and pressure are signs of left ventricle diastolic dysfunction.

Spatial Mismatch Between Angiographic Obstruction and Plaque Destabilization in Acute Coronary Syndromes: A Conceptual Narrative Review

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT The identification of the “culprit lesion” in acute coronary syndromes (ACS) traditionally relies on coronary angiography, assuming that the most severe stenosis, abrupt occlusion, or largest filling defect marks the site of plaque destabilization.

Novel parameter for assessment of left atrial size in patients with hypertension: ratio of left atrial volume to left ventricular volume.

Chinese medical journal, 2010
Left atrial enlargement has been suggested as a more robust marker of diastolic dysfunction. We hypothesize that the ratio of left atrial volume to left ventricular volume (LAV/LVV) may be more reasonable to reflect left atrial enlargement in the patients with hypertension, because hypertensive patients have a characteristic of concentric remodeling of

Biventricular Pressure‐Volume Loop Analysis in an LVAD Patient Optimized With Impella RP Flex

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Right ventricular (RV) failure after left ventricular assist device (LVAD) implantation is a serious complication which may necessitate temporary mechanical support in refractory cases. Here we describe a 63‐year‐old man with end‐stage ischemic cardiomyopathy and severe combined pre‐ and post‐capillary pulmonary hypertension who developed ...

Double Transeptal Puncture for SAPIEN M3 Transcatheter Mitral Valve Replacement: Initial Experience, Indications, and Technique

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT The SAPIEN M3 system has been recently approved for transcatheter mitral valve replacement (TMVR). The transeptal guide sheath is used to deploy the dock, which is completely released before inserting and deploying the M3 valve using the same femoral access, transeptal puncture (TSP) and guide sheath.

Assessment of left atrial function in dogs with myxomatous mitral valve disease by biplane simpson’s method

Arquivo Brasileiro de Medicina Veterinária e Zootecnia
The relationship between the diameter of the left atrium (LA) and aorta (Ao) is considered as a prognostic factor in chronic mitral valve disease. As the left atrium is a three-dimensional structure, methods based on measurement of the chamber volume can

Association of left atrial pressure with left atrial volume and N-terminal prohormone brain natriuretic peptide in children with cardiomyopathy

, 2018
Enlargement of the left atrium is a non-invasive marker of diastolic dysfunction of the left ventricle, a determinant of prognosis in children with cardiomyopathy.

Secretopathies emerge as a new class of neurocristopathies

Developmental Dynamics, EarlyView.
Abstract Neural crest cells are a transient embryonic population of cells that give rise to a wide range of structures, including craniofacial cartilage and bone, peripheral neurons and glia, as well as components of the cardiac outflow tract, among others.
