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 ...

The proportion of patients with aortic regurgitation grade 2 or greater was similar for patients with or without mismatch, both before hospital discharge (P = 0.33) and at 6 months (P = 0.11). In ...

Mismatch Higher After Surgery. The overall incidence of patient-prosthesis mismatch was lower among TAVR patients than SAVR patients in the randomized trial (46.4% vs 60.0%; P < .001), as were rates ...

The hazard ratio (HR) for 1-year post–ViV-procedure mortality for severe PPM at the prior surgical AVR was 1.88 (95% CI, 1.07–3.28; P=0.03) compared with no mismatch or only moderate mismatch ...

Aortic-valve stenosis can be complicated by bleeding, particularly that due to gastrointestinal angiodysplasia (Heyde's syndrome). 1–3 This hemorrhagic syndrome is associated with acquired type ...

Researchers say transcatheter aortic valve ... They also examined the performance of the replacement valve using echocardiography, ... This phenomenon is referred to as prosthesis-patient mismatch.

As the disease progresses and the aortic valve leaflets lose their mobility, the intensity of S2 decreases. When the S2 sound is no longer audible, the aortic stenosis is relatively severe.

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.

Washington, D.C. – May 1, 2025 – New data finds women 8% more likely to experience major complications after transcatheter aortic valve implantation (TAVI) and 50% more likely after left ...

Edwards Lifesciences said Wednesday its transcatheter aortic valve replacement (TAVR) device is similarly effective in patients with small and large aortic annuli. Earlier this year, Medtronic ...

At baseline, the mechanical valve group tended to be younger (55.7 vs 65.2) and had less aortic stenois (82.4% vs 89.5%), but more moderate and severe aortic regurgitation (39.0% vs 30.5%).
