SAN DIEGO — Severe prosthesis–patient mismatch (PPM) occurs in more than 10% of patients after transcatheter aortic valve replacement (TAVR) and increases the risk for death but not stroke ...

In patients who have undergone transcatheter aortic valve replacement (TAVR), the presence of an imbalance between prosthesis functioning and body size can lessen the positive hemodynamic impact of ...

In high-risk patients with severe aortic stenosis, prosthesis-patient mismatch is more common following surgical aortic valve replacement (SAVR) than transcatheter aortic valve replacement (TAVR).

Patient-prosthesis mismatch after aortic valve replacement is associated with a high rate of events and increased mortality. The authors highlight the importance of identifying susceptible patients.

Aortic-valve stenosis is a progressive condition; end-stage disease leads to death due to obstruction of left ventricular outflow. Aortic-valve replacement is the only effective therapy. Transcathe ...

Von Willebrand factor abnormalities are directly related to the severity of aortic stenosis and are improved by valve replacement in the absence of mismatch between patient and prosthesis.

In that surgery, called transcatheter aortic valve replacement, or TAVR, cardiologists insert a replacement valve through a patient’s groin and thread it all the way to the heart.

People didn't have to wait long after transcatheter aortic valve replacement (TAVR or TAVI) to safely undergo noncardiac surgery, though suboptimal device performance should give pause for another ...

Prosthesis-patient mismatch refers to when the valve is too small for the body. Mean gradient is a measure of aortic stenosis severity.

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 ...

The TAVR procedure has revolutionized a challenging task in heart care: fixing stiff valves. And it has made the process much easier for patients, getting them back to an active life faster.
