SMART study shows hemodynamic benefits of self-expanding valves in aortic stenosis patients

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.

New transcatheter heart valve shows promise in treating aortic stenosis

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).

New scoring system identifies risks in coronary artery interventions

New data demonstrated that a left main (LM) bifurcation-specific novel scoring system (LM V-RESOLVE), based on three simple baseline angiographic findings, could help to rapidly discriminate lesions at risk of side branch (SB) occlusion during LM bifurcation percutaneous coronary intervention (PCI) – reducing risk during the procedure.
