Echocardiography: An overview

Journal of the American College of Cardiology, 1983
In the past 25 to 30 years echocardiography has become a basic examination in clinical cardiology. Thus, it is becoming increasingly necessary for clinicians to be able to utilize it intelligently. Like all medical procedures echocardiography has advantages and limitations, and physicians need to know both.

Ischaemic strokes in patients with pulmonary arteriovenous malformations and hereditary hemorrhagic telangiectasia: associations with iron deficiency and platelets. [PDF]

, 2014
BackgroundPulmonary first pass filtration of particles marginally exceeding ∼7 µm (the size of a red blood cell) is used routinely in diagnostics, and allows cellular aggregates forming or entering the circulation in the preceding cardiac cycle to lodge ...

Lactate Metabolic Reprogramming Mediated by CircRNA–LDHA Complex Facilitates Innate Immune Evasion of Liver Cancer

Advanced Science, EarlyView.
CircSMPD4 physically combines with lactate dehydrogenase A (LDHA) and reduces its acetylation level via SIRT2‐dependent deacetylation, thereby inhibiting chaperone‐mediated autophagy‐lysosome degradation of LDHA. Upregulating LDHA leads to increasing lactate production and extracellular export, which in turn suppresses natural killer cell cytotoxicity ...

Left ventricular systolic function changes in hypertrophic cardiomyopathy patients detected by the strain of different myocardium layers and longitudinal rotation

BMC Cardiovascular Disorders, 2017
Background Impairment of left ventricular (LV) longitudinal function has an important role in hypertrophic cardiomyopathy (HCM). This research investigated an association between the longitudinal strain of different myocardial layers, longitudinal ...

Physiological and clinical consequences of relief of right ventricular outflow tract obstruction late after repair of congenital heart defects. [PDF]

, 2006
BACKGROUND: Right ventricular outflow tract obstruction (RVOTO) is a common problem after repair of congenital heart disease. Percutaneous pulmonary valve implantation (PPVI) can treat this condition without consequent pulmonary regurgitation or ...

Microgel Aspect Ratio Influences Injectable Granular Hydrogel Scaffold Pore Structure and Cellular Invasion for Tissue Repair

Advanced Science, EarlyView.
Granular hydrogels are being developed for the repair of tissues, mostly with the use of spherical microgels. Here, injectable granular hydrogels formed from anisotropic particles (i.e., rod‐like) are explored to improve cellular invasion by increasing scaffold void volume fraction.

Prognostic value of echocardiographic indices of left atrial morphology and function in dogs with myxomatous mitral valve disease [PDF]

, 2018
Background: The prognostic relevance of left atrial (LA) morphological and functional variables, including those derived from speckle tracking echocardiography (STE), has been little investigated in veterinary medicine.

Decreased RYR2 Cluster Size and Abnormal SR Ca2+ Release Contribute to Arrhythmogenesis in TMEM43‐Related ARVC

Advanced Science, EarlyView.
The TMEM43 ‐ P386S mutation causes arrhythmogenic right ventricular cardiomyopathy (ARVC) by mislocalizing itself from nuclear envelope (NE) to cytoplasm, disrupting lamin B2 (a novel TMEM43 interactor) localization, NE integrity and chromatin accessibility, causing hyper ‐ phosphorylation and reduced expression/clustering of ryanodine receptor type 2 (

Non-compaction cardiomyopathy – brief review [PDF]

, 2017
Left ventricular non-compaction cardiomyopathy is a genetic disorder characterized by the presence of two myocardial layers with numerous prominent trabeculations and deep inter-trabecular recesses that communicate with the ventricular cavity.
