Patients with failure of a surgical aortic bioprosthesis—which frequently occurs 10 to 15 years after surgery—fare worse after a transcatheter valve-in-valve (ViV) fix if the original valve ...

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.

SAN DIEGO — Severe prosthesis-patient mismatch conferred elevated risk for mortality and HF hospitalization at 1 year after transcatheter aortic valve replacement, according to a presentation at ...

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 ...

Tasca G et al. (2006) Impact of prosthesis–patient mismatch on cardiac events and midterm mortality after aortic valve replacement in patients with pure aortic stenosis. Circulation 113: 570–576 ...

Severe mismatch was tied to several prosthesis and patient factors -- the strongest being: Valve-in-valve procedure: OR 2.775, 95% CI 2.530-3.043 ...

At discharge and 1 year, patients who underwent TAVR had significantly lower mean aortic valve gradient and larger valve area compared with those who underwent surgical AVR (P < .001 for both).

The significantly lower rate of moderate or severe patient-prosthesis mismatch (PPM) at 1 year with the self-expanding valves -- 11.3% vs 29.4% and 3.0% vs 8.5%, respectively -- was linked with ...

SAN DIEGO--In the largest multi-institutional study to date, led by researchers from Penn Medicine, the team found that among patients who underwent a transcatheter aortic valve replacement (TAVR ...

Expandable prosthesis resolves advanced aortic valve disease Date: September 30, 2011 Source: University Hospitals Case Medical Center Summary: Among individuals 65 years and older, as many as 30 ...

Prosthesis-patient mismatch (PPM) after surgical aortic valve replacement has become less common over time, but it remains associated with worsened clinical outcomes, a new study shows. Also, a second ...

Patient-prosthesis mismatch (PPM) is common after aortic valve replacement and has been shown to be associated with poor hemodynamic and symptomatic status, a high rate of cardiac events, and ...
