(Press-News.org) Long Beach, Calif. – May 3, 2024 – Recent findings from a study on a transcatheter heart valve (THV) system, which includes a new class of transcatheter aortic valve, showed positive results in the device's ability to function as a healthy and natural aortic valve in patients with aortic stenosis (AS). The late-breaking data will be presented today at the Society for Cardiovascular Angiography & Interventions (SCAI) 2024 Scientific Sessions.
AS is a thickening and narrowing of the aortic valve that can reduce blood flow to the body and potentially lead to heart failure. For some patients, transcatheter aortic valve replacement (TAVR) can be an effective treatment option and has become more common in recent years.
A prospective non-randomized, single-arm, single-center, First-in-Human (FIH) study of 28 patients, was designed to evaluate safety and feasibility in patients with severe symptomatic AS with the DurAVR™ Transcatheter Heart Valve (THV) System from Anteris Technologies. Clinical, echo, computerized tomography (CT), and cardiac MRI assessments were performed for up to one year.
The DurAVRTM valve was successfully implanted in 100% of the cases. All patients showed excellent post-procedural hemodynamic results, despite a small mean annulus size. No moderate or severe paravalvular leak was observed. Additionally, laminar flow was consistently displayed on cardiac MRI. For those patients at 12-month follow-up, the valve also showed a favorable safety profile in all patients and no valve-related complications, strokes, life-threatening bleeding, or reoperations occurred.
“We are excited to share such favorable results early on in our trial as it represents a novel option for TAVR procedures by providing encouraging evidence of improved hemodynamics and normalized blood flow characteristics associated with the system,” said Azeem Latib, MD, Director of Interventional Cardiology and Structural Heart Interventions at Montefiore Medical Center in New York. “We look forward to sharing additional results that support the valve performance characteristics and how similar they are to the ones of a healthy aortic valve.”
Additional testing on the DurAVR™ THV System is currently underway, and more data is expected to be presented this year.

Long Beach, Calif. – May 3, 2024 – Additional analysis from the SMall Annuli Randomized To Evolut or SAPIEN (SMART) study demonstrated clinical non-inferiority of self-expanding valves (SEV) versus balloon-expandable valves (BEV) in aortic stenosis patients undergoing transcatheter aortic valve replacement (TAVR) and confirmed valve performance superiority over time based on hemodynamics. Data also showed similar positive results in two age groups (< or ≥ 80 years old). The late-breaking results were presented today at the Society for Cardiovascular Angiography & Interventions ...
Study Title: Efficacy of [177Lu]Lu-PSMA-617 versus ARPI change in taxane-naive patients with metastatic castration-resistant prostate cancer by pre-randomization ARPI (PSMAfore)
Publication: American Urological Association Annual Meeting Plenary, May 3, 2024
Dana-Farber Cancer Institute author: Xiao X. Wei, MD
Summary: In a follow-on analysis of results from the phase 3 PSMAfore study, clinical investigators from Dana-Farber and elsewhere found that clinical outcomes consistently favored 177Lu-PSMA-617 over a change from one androgen receptor pathway inhibitor (ARPI) to another, regardless of which ARPI patients received first. ...

WASHINGTON (May 3, 2024) – Children with life-limiting rare diseases and their caregivers face tremendous stress and anxiety about the heart-breaking decisions before them. A new intervention – designed at Children’s National Hospital to support the palliative needs of these families – improved their spiritual and emotional well-being, according to new research published in the journal, Pediatrics.
Called FACE Rare (FAmily CEntered Pediatric Advance Care Planning Intervention for Rare Diseases), the counseling tools were found to be safe, effective and increased feelings of peace among families in this underserved ...
A research group at the Department of Biochemistry and Molecular Biology of the University of Seville has made a significant advance by discovering the crucial role of the protein Galectin-3 in the progression of various types of brain tumours. In these tumours, the most abundant immune system cells, microglia and macrophages, overexpress Galectin-3, which creates an immunosuppressed environment which inhibits the action of other immune cells against cancer cells.
In vitro findings have shown that specific inhibition of Galectin-3 in microglial cells promotes expression of proinflammatory markers and reverses the presence of key immunosuppressive ...

Climate change will cause an increase in extreme winter storms combining strong winds and heavy rainfall over the UK and Ireland, new research has shown.
The new study was led by experts at Newcastle University and the Met Office and investigated how future climate change may influence compound wind-rain extremes, which are events where extreme wind and rainfall occur simultaneously.
The researchers analysed data from climate simulations covering control (1981-2000) and future (2060-2081) periods, ...
Researchers working on solutions for antifungal resistance are being encouraged to apply to a new £3.4 million fund led by the University of Exeter with UK government funding.

Evidence from archaeological sites in the medieval English city of Winchester shows that English red squirrels once served as an important host for Mycobacterium leprae strains that caused leprosy in people, researchers report May 3 in the journal Current Biology.
“With our genetic analysis we were able to identify red squirrels as the first ancient animal host of leprosy,” says senior author Verena Schuenemann of the University of Basel in Switzerland. “The medieval red squirrel strain we recovered is more closely related to medieval human strains from the same city than to strains isolated from infected ...
