LOS ANGELES — Aortic mechanical valves are associated with better survival than bioprosthetic valves in patients aged 60 years or younger, showed 12-year survival data from a large surgical ...

Q. I have a leaky heart valve that may need surgery down the road. Can you tell me about heart-valve surgery in one of your columns? A. First, let’s explain briefly how the heart works.

Valves may eventually be made of carbon-based materials (no metal). Meanwhile, a 2019 study by engineers at the University of Bern ... Association Between Antithrombotic Medication Use After ...

The researchers reviewed data on nearly 110,000 patients who underwent surgical replacement of aortic valves between the ages of 40 and 79. They found that in those aged 60 or younger, mechanical ...

Decline in mechanical valve use: Despite superior outcomes in younger populations, mechanical valve use decreased from 20% to 10% over the study's 12-year period. Survival advantage: Mechanical ...

Bicuspid aortic valve disease, where the aortic valve has two leaflets instead of the normal three, is the most common congenital heart defect, affecting up to 2% of the population.

(Reuters) - Middle-aged adults who need an aortic valve replacement fare better with mechanical devices than with the valves made from animal tissues that they currently most often receive ...

Transcatheter heart valve (THV) underexpansion after transcatheter aortic valve replacement may be associated with worse outcomes. THV expansion can be assessed fluoroscopically using a pigtail for ...

2 Centre National de Référence pour le syndrome de Marfan et apparentés, Hôpital Bichat, AP-HP, Paris, France Background Bicuspid aortic valve (BAV) is related to aortic dilatation, but patterns/rates ...

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 ...

Coronary artery disease (CAD) is present in 40–75% of patients undergoing transcatheter aortic valve implantation (TAVI) for severe symptomatic aortic stenosis. Currently, the indication for TAVI is ...

Direct aortic measurements using phase contrast allow quantitation of volumetric flow across the aortic valve and are highly reproducible and accurate compared with echocardiography. However, this ...
