Abiomed Inc., has worked the ventricular assist device (VAD) space for a number of years with its Impella series of VADs, and a study coming out of Japan seems to affirm investors’ confidence in these devices. This registry study demonstrated that the combination of Impella devices and extracorporeal membrane oxygenation (ECMO) provides a 30-day survival rate of more than three in four patients with cardiogenic shock, an outcome that is said to support the notion that the native heart tissue can recover from myocarditis, an especially salient consideration for those who contracted the SARS-CoV-2 virus.
In an unexpected turn of events, Medtronic plc presented results from the Symplicity HTN-3 trial at year 3 showed sustained reductions in blood pressure with radiofrequency renal denervation (RDN) for resistant hypertension, contrary to the trial’s results at the six-month mark—and it wasn’t alone in showing positive results for the procedure.
It has long been known that patients recover more quickly from transcatheter aortic valve replacement (TAVR) than from open-heart surgery for valve replacement (SAVR) and results at two years looked good, too, with very similar outcomes. The question remained what happens in the longer term?
A new study has found that despite the risk, many patients are open to interventional procedures such as renal denervation (RDN) if it can lead to improved blood pressure. RDN is performed under local anesthetic and uses radio frequency ablation to burn the nerves in the renal arteries. The process causes a reduction in nerve activity, which decreases blood pressure.
Despite the morbidity associated with coronary artery bypass graft, this procedure has never been entirely displaced by percutaneous coronary intervention. The results from the latest in a series of studies does not seem to help the case for drug-eluting stents (DES) for patients with three-vessel disease, as the data from this study failed to demonstrate non-inferiority for DES devices implanted with the help of fractional flow reserve measurement to ensure optimal stent placement.
Abbott Laboratories had a busy Transcatheter Cardiovascular Therapeutics (TCT) 2019 conference. Among the news it generated was the unveiling of new analyses of the COAPT trial on the cost-effectiveness of Mitraclip vs. guideline-directed medical therapy (GDMT) alone in heart failure patients with secondary mitral regurgitation (MR).
SAN FRANCISCO – Abbott Laboratories expects that its self-expanding transcatheter aortic valve replacement (TAVR) system Portico will be able to become a top competitive product. A pivotal trial of Portico has found that the implant is noninferior to current FDA-approved TAVR systems that are marketed in the U.S. The results from the 750-patient, randomized trial were presented here last week at the Transcatheter Cardiovascular Therapeutics (TCT) conference.
SAN FRANCISCO – As the transcatheter aortic valve replacement (TAVR) field matures, it is becoming increasingly difficult to develop a new implant that can distinguish itself vs. competitors. The incremental benefits are narrowing rapidly, making it tough to distinguish new iterations from one another using standard, randomized trials.
