Study of Boston Scientific ’s Lotus, Medtronic’s CoreValve shows similar outcomes at 2 years

Two-year results from a head-to-head study comparing transcatheter aortic heart valve replacement devices from both Boston Scientific (NYSE:BSX) and Medtronic (NYSE:MDT) indicated similar outcomes for the competing products. The study, published recently in the journal JAMA Cardiology, compared Marlborough, Mass.-based Boston Scientific’s Lotus valve to Fridley, Minn.-based Medtronic’s CoreValve system. Investigators in the study compared outcomes for 912 patients with high or extreme risk and severe, symptomatic aortic stenosis after treatment with one of the two devices. Patients, treated between September 22, 2014 and December 24, 2015, were randomized two to one to receive the Lotus valve or CoreValve system at 55 centers spanning North America, Australia and Europe, according to study results. Main outcomes being explored by researchers were all-cause mortality and all-cause mortality or disabling stroke at two years. Other factors examined included overall stroke, disabling stroke, repeat procedures, rehospitalization, valve thrombosis and pacemaker implantation. At two years, results indicated similar rates of all-cause mortality, mortality and disabling stroke between the competing valve devices, according to the study results. All-cause death was reported at 21.3% with the Lotus valve, versus 22.5% with the CoreValve, while rates of all-cause mortality or disabling stroke were 22.8% with the Lotus and 27% with the CoreValve. Rates of overall str...

Publication date: Available online 18 March 2019Source: Thinking Skills and CreativityAuthor(s): Leon de BruinAbstractThis paper explores musical improvisation, examining the learning processes utilized in acquiring improvisational skill, and the development of creative processes and expression of six elite Australian improvisers. Taking a socio-constructivist approach to examining how groups and individuals engage in, sustain, support, and productively develop processes of collaborative learning, this phenomenological study investigates the temporal and sequential characteristics of SRL and SSRL regulation that can inform...

This study provides evidence of adoption of TORS in Australia and New Zealand; however, there is a perception that significant barriers to adoption persist. Results from this study may help guide decisions on how we train and license surgeons in the era of this technology.

Excellent outcomes of transcatheter aortic valve replacement (TAVR) have been experienced by patients with aortic stenosis at high and intermediate risk of surgery.1 Findings from large randomised trials1,2 have shown survival with TAVR that is similar to or improved compared with bioprosthetic surgical aortic valve replacement (SAVR), and very low stroke rates have been observed with new-generation devices. Investigators of echocardiographic follow-up studies3 have consistently reported low transvalvular gradients up to 5 years after TAVR and SAVR, with slightly greater aortic valve areas after TAVR than after SAVR.

Authors: Montarello NJ, Nelson AJ, Sidharta SL, Worthley SG Abstract Transcatheter aortic valve implantation (TAVI) can now be considered a standard of care for inoperable and high-risk surgical patients with severe aortic stenosis, and its uptake worldwide is rapidly increasing. Indeed, many centers performing the procedure have now moved towards treating intermediate-risk patients with TAVI rather than referring them for surgical aortic valve replacement. Although the incidence of peri-procedural acute and subacute stroke following TAVI has fallen to 2-5%, its occurrence can be life-threatening and life-changing,...

This paper provides recommendations on the pre-treatment clinical assessment of patients presenting with head and neck cancer. Recommendations • Comorbidity data should be collected as it is important in the analysis of survival, quality of life and functional outcomes after treatment as well as for comparing results of different treatment regimens and different centres. (R) • Patients with hyp...

In this study, cangrelor was discontinued 1-6 hours prior to surgery, while aspirin was continued throughout the perioperative period. Bridging with cangrelor did not increase major bleeds prior to surgery, though minor bleeds, mostly ecchymosis at venipuncture site, was higher. P2Y12 assay documented sufficient platelet inhibition corresponding to levels required for anti thrombotic effect [1]. Cangrelor is awaiting approval and more large scale trials regarding the use of bridging are needed. Reference 1. Angiolillo DJ et al; BRIDGE Investigators. Bridging antiplatelet therapy with cangrelor in patients undergoing ...

Abstract Atrial fibrillation (AF) confers a substantial risk of stroke. Recent trials comparing vitamin K antagonists (VKAs) with non-vitamin K antagonist oral anticoagulants (NOACs) in AF were performed among patients with so-called "non-valvular" AF. The distinction between "valvular" and "non-valvular" AF remains a matter of debate. Currently, "valvular AF" refers to patients with mitral stenosis or artificial heart valves (and valve repair in North American guidelines only), and should be treated with VKAs. Valvular heart diseases, such as mitral regurgitation, aortic st...
