In conclusion, reduced aortic-valve leaflet motion occurred in patients with bioprosthetic aortic valves and was easily detected noninvasively by four-dimensional, volume-rendered CT.

A new study compares two leading types of aortic valve replacements and finds they have similar performance in terms of long-term risk of stroke and death for patients.

Spotlight on Bioprosthetic Aortic Valves Reduced leaflet motion in some bioprosthetic aortic valves prompts further investigation, additional clinical imaging.

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 ...

In an analysis of about 460 patients with failed bioprosthetic aortic valves who underwent transcatheter valve-in-valve implantation, overall survival at one year was 83 percent, with survival ...

Michael Dismorr at the research group Thoracic Surgery, the Department of Molecular Medicine and Surgery, defended his thesis "Epidemiological studies of bioprosthetic aortic valves" on November ...

The bioprosthetic venous valve, called VenoValve, is about an inch-long stainless-steel frame with a porcine aortic leaflet – or a flap from well-preserved pig heart valve tissue – sewn to it.

"The decision between a bioprosthetic and a mechanical valve is one of the most consequential for patients requiring aortic valve replacement," said Dr. Michael Bowdish, lead author of the study ...

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 ...

For patients with failed bioprosthetic surgical valves, the choice of valve-in-valve (ViV) transcatheter aortic valve replacement (TAVR) carried upfront advantages, but was ultimately associated ...

The data, which represent the longest clinical follow-up for Edwards' bioprosthetic surgical aortic valve with RESILIA tissue with a mean follow-up of 7.7 years, were presented today at the 103 rd ...

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 ...
