The Ross procedure for aortic valve replacement was associated with better long-term survival compared with biological and mechanical AVR, researchers reported.In addition, according to new long ...

LOS ANGELES -- Survival outcomes favored mechanical valves for isolated surgical aortic valve replacement (SAVR) for people until age 60, after which a tissue valve may start to have an advantage ...

Bioprosthetic and mechanical aortic valve replacement were associated with similar 15-year rates of all-cause mortality and stroke, according to data published in JAMA.Researchers evaluated 4,253 ...

Biological vs Mechanical Valves in Surgery. The use of biological valves for surgical AVR is steadily increasing, but there are limited data addressing potential differences in outcomes between ...

LOS ANGELES, CA—In patients ages 60 years or younger undergoing surgical aortic valve replacement, mechanical valves are associated with a survival benefit compared with bioprosthetic valves, ...

Less aggressive anticoagulation therapy, combined with low-dose aspirin, can be used safely in conjunction with a newer generation mechanical heart valve, a study shows. Patients under 65 years of ...

Aortic valve replacement can be performed using either prosthetic valves—broadly divided into bioprostheses and mechanical valves—cadaveric aortic valves (homografts), or the patient's own ...

The aortic valve regulates blood flow by opening and closing, and when it stops working an aortic valve replacement (AVR) surgery must be done for blood flow to resume like normal, delivering oxygen ...

STOCKHOLM, SWEDEN — Long-term survival rates are about two-thirds higher for patients in their 50s who undergo aortic-valve replacement with mechanical prostheses compared with bioprostheses, a ...

The patients were randomized to receive either lower-dose warfarin (n=190; INR 1.5–2.0) or to continue standard-dose warfarin (INR 2.0–3.0), for three months following mechanical AVR with the ...
