Calcific aortic valve disease is the pathological remodeling of valve leaflets. The initial steps in valve leaflet osteogenic reprogramming are not fully understood. As TERT (telomerase reverse ...

Accurate detection and segmentation of lung tumors on CT scans is critical for monitoring cancer progression, evaluating treatment responses and planning radiation therapy. Currently, experienced ...

Current guidelines suggest balloon aortic valvuloplasty (BAV) to be considered as a bridge to surgical aortic valve replacement or to transcatheter intervention in haemodynamically unstable patients ...

At just the right moment, the right and left atria empty their accumulated blood into the right and left ventricles. The four heart valves (tricuspid, pulmonary, mitral and aortic) open and close at ...

The aortic valve, influenced by factors such as endothelial dysfunction, inflammation, oxidative stress, lipid metabolism disorders, calcium deposition, and extracellular matrix remodeling, undergoes ...

Researchers used whole genome microarray genotyping on 272 bicuspid aortic valve patients with early onset valve or aortic disease and 272 biological relatives. They analyzed all copy number ...

Based on these data, we propose an algorithm for classifying patients in terms of PPM risk, considering the presence of initial RBBB, AVCS and the type of valve used. Finally, in the current technical ...

A calcium-scoring CT is a low-cost, non-invasive heart scan that identifies how much calcified plaque is in the coronary arteries. The plaque in heart's arteries can narrow or block them and can ...

1. Pulmonary valve. 2. Ostium of the left pulmonary artery. 3. Ostium of the right pulmonary artery. 4. Ductus arteriosus. 5. Descending thoracic aorta. B: Aortic valve and single coronary artery ...

Description Aortic stenosis occurs when the aortic valve, which separates the main pumping chamber of the heart from the circulation, becomes narrowed. This may reduce the flow of blood out of the ...
