The transcatheter aortic valve replacement market received one of the biggest jolts of the year when FDA expanded indications of both Edwards Lifesciences and Medtronic’s valves. FDA’s measure would open up the valves to be used in younger and low-risk patients. The agency said these transcatheter valves – Edwards’ Sapien 3, and Sapien 3 Ultra, with Medtronic’s CoreValve Evolut R and CoreValve Evolut PRO – were previously indicated only for patients at intermediate or higher risk for death or major complications duri...

There has been a flurry of news recently about a procedure called trans-catheter aortic valve replacement (TAVR) for the treatment of the common heart condition aortic stenosis (AS). You may even know people who have had this procedure performed. What exactly is TAVR? And what’s all the excitement about? What is aortic stenosis? First, it’s important to understand the condition that TAVR is designed to treat, aortic stenosis. The aortic valve is the last structure of the heart through which blood passes before entering the aorta and circulating throughout the body. The aortic valve has three flaps, called leafl...

AbstractAims  Owing to new evidence from randomized controlled trials (RCTs) in low-risk patients with severe aortic stenosis, we compared the collective safety and efficacy of transcatheter aortic valve implantation (TAVI) vs. surgical aortic valve replacement (SAVR) across the entire spectrum of surgical risk patients.Methods and results  The meta-analysis is registered with PROSPERO (CRD42016037273). We identified RCTs comparing TAVI with SAVR in patients with severe aortic stenosis reporting at different follow-up periods. We extracted trial, patient, intervention, and outcome characteristics following predef...

Abstract Valvular heart diseases are one of the most frequent causes for heart failure. Degenerative diseases of the aortic and mitral valve as well as a dysfunctional tricuspid valve disease result in a worse clinical outcome if severe. Minimal-invasive, surgical and/or catheter-based structural heart disease (SHD) interventions have recently seen a dramatic increase. Transcatheter aortic valve implantation (TAVI) for severe aortic stenosis (AS) is a disruptive technology, and next generation devices and careful patient selection will minimize limitations of TAVI such as paravalvular leak, conductance disturbance...

Results from trials of both Medtronic‘s (NYSE:MDT) and Edwards Lifesciences‘ (NYSE:EW) transcatheter aortic valve replacement systems exploring their use in low-risk patients indicated that the devices were as safe as open surgery, paving the way for possible new indications for TAVR technology. Data from the trials were presented over the weekend at the American College of Cardiology 68th Annual Scientific Session 2019 in New Orleans and simultaneously published in the New England Journal of Medicine. Currently, TAVR devices are only approved by the FDA for treating severe aortic valve stenosis in patients at ...

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 Se...
