New data presented at the Cardiovascular Research Technologies (CRT) 2023 meeting reinforced the safety and effectiveness of Boston Scientific Corp.’s Watchman FLX left atrial appendage occlusion (LAAO) device in routine, real-world clinical care. Building on positive 45-day outcomes presented at CRT 2022, the analysis shows sustained low stroke rate at one year, including ischemic stroke.
Pulsed field ablation (PFA) may not be the final word where energy sources for atrial fibrillation (AF) ablation are concerned, but several companies have adopted development programs that propose the use of PFA as an alternative to conventional energy sources. Dublin-based Medtronic plc appears to have at least a narrow lead over the competition in the PFA space thanks to the results of the PULSED AF pivotal study presented at the 2023 American College of Cardiology Scientific Sessions.
Tricuspid valve regurgitation has lagged mitral regurgitation where device development is concerned, but new one-year data from the TRILUMINATE study of the Triclip device suggests that device therapy is safe and cuts down on regurgitation in a manner that makes the condition much more tolerable for patients. At this point, however, the data do not yet offer much difference when it comes to mortality and rehospitalization compared to medical management, a gap Abbott will have to overcome if it wants to maximize its investment in this underdeveloped area of medical technology.
Abbott Laboratories scored a major win for its Mitraclip device thanks to data from the COAPT study for secondary mitral valve regurgitation. The latest data from this study show a stunning difference in two-year mortality compared to maximized medical management only – 29% on the device versus 46% on medical management – but differences between the COAPT study results and outcomes seen in the MITRA-FR study will force cardiologists to dive into the data to ensure that their patient selection practices account for critical differences in the conduct of these two studies.
Surgical aortic valve replacement (SAVR) devices are widely believed to be considerably more durable than transcatheter aortic valve replacement (TAVR) devices, but five-year data for Medtronic plc’s Corevalve Evolut, presented this week at the Cardiovascular Research Technologies Conference in Washington, seem to suggest that TAVR devices are closing that gap.
Abbott Laboratories continues to push its presence in the cardiovascular market with offerings for the left atrial appendage (LAA) closure and transcatheter aortic valve implant (TAVI) markets, both of which generated affirmative data presented at this year’s edition of the annual meeting of Cardiovascular Research Technologies (CRT 2023) in Washington.
While still pending clearance in the U.S., Medtronic plc’s Minimed 780G advanced hybrid closed loop (AHCL) system continues to post strong results in clinical trials. Results of two studies presented at the 2023 Advanced Technologies & Treatments for Diabetes Conference in Berlin on Feb. 27 demonstrated that patients with type 1 diabetes (T1D) who used the device for one year maintained a 26.7% increase in time in range for adults and a 14% increase in time in range for children aged 7 to 17 compared to their baseline using multiple daily injections with a continuous glucose monitor (CGM).
Esophageal cancer is often referred to as the “silent killer” because few people show any symptoms until after the cancer has spread. If localized, five-year survival rate is 46%, but that drops to just 5% when malignancy has reached distant parts of the body.
To restore hearing function in patients with hearing loss or deafness, cochlear implantation is seen as the only method that works, but insertion of the electrode array may cause direct mechanical injury to the cochlea, with the subsequent loss attributed to an inflammatory response driven by proinflammatory cytokines, reactive oxygen species and apoptotic signals.
Neurodiagnostics LLC (dba Synaps Dx) and Linus Health Inc. reported significant advances for their dementia diagnostics Feb. 16, adding to the liquid biopsies and radiologic studies currently used and potentially expanding access to beneficial treatments for Alzheimer’s disease (AD) and other dementias.
