Abstract

To study the feasibility and additional value of real time three-dimensional transthoracic echocardiography (RT3D-TTE) for anatomical and functional assessment of malformed aortic valve (AV) compared to conventional two-dimensional TTE (2D-TTE). Malformed AV was evaluated in 35 patients (mean age 18 ± 9.5 years, 70% male) by both 2D-TTE and RT3D-TTE. The anatomical definition of aortic cusps (number, direction, and commissures) was evaluated by a 3-point visualization score (1: nonvisualized, 2: inadequate, 3: adequate). 2D-TTE and RT3D-TTE measurements included AV area and maximum diameters of both AV annulus and left ventricular outflow tract (LVOT). Adequate visualization of AV cusps was achieved in 86% of patients by RT3D-TTE compared to 63% by 2D-TTE. The mean and median visualization score obtained by RT3D-TTE were higher than that by 2D-TTE. The opening of commissures was detected in (80%) of patients by RT3D-TTE compared to (34%) by 2D-TTE. AV area planimetry could be obtained in 77% of patients by RT3D-TTE compared to 43% by 2D-TTE. RT3D-TTE visualization score of AV cusps and commissures showed better interobserver agreement (Kappa: 0.62 and 0.72, respectively) than 2D-TTE (0.58 and 0.69, respectively). RT3D-TTE and 2...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
