JenaValve announced today that it began patient enrollment in the ARTIST study evaluating its Trilogy heart valve system.

A normal aortic valve (left) versus a defective aortic valve (right) and their different sound signals (purple). The sound data was used to generate graphs at the bottom corners, which differ ...

Possible causes include anxiety, fever, exercise, and an overactive thyroid gland. Though most causes of a bounding pulse are ...

Since the aortic valve is normal the QK d interval is normal. However, the greater time required for ejection of the large stroke volume from the left ventricle results in a somewhat prolonged QK ...

Aortic stenosis, affecting nine million people globally, is often unnoticed as symptoms are mistaken for aging. This heart condition, common in elderly, restricts blood flow due to valve narrowing, ...

The normal aortic jet velocity is less than 2.5 m/sec. Symptoms usually do not occur in patients until the aortic jet velocity is greater than 4.0 m/sec and the valve area is less than 1.0 cm 2.

Aortic valve repair aims to restore the normal functioning of the aortic valve without replacing it entirely. It may involve addressing specific issues or defects in the valve, such as: ...

Frequency and Significance of Intravascular Hemolysis Before and After Transcatheter Aortic Valve Implantation in Patients With Severe Aortic Stenosis, The American Journal of Cardiology, 121, 1 ...

Moreover, Latib reported that the biomimetic TAVR valve restored normal aortic flow, with no significant differences in flow displacement or flow reversal ratio compared with a healthy aortic ...

A normal aortic valve (left) versus a defective aortic valve (right) and their different sound signals (purple), pictured in an undated photo illustration.

Graphical diagnostics: Signals from a normal aortic valve (left) show two separated sounds while those from a defective aortic valve (right) display diamond-shaped murmurs. The sound data were used to ...
