Elixir Medical Corp. reported positive 12-month data from the Infinity-Swedeheart trial that compared its Dynamx coronary bioadaptor system to Medtronic plc’s Resolute Onyx zotarolimus drug-eluting stent in patients requiring percutaneous coronary intervention with coronary artery disease.
Elixir Medical Corp. reported positive 12-month clinical data from the Desyne BDS Plus randomized controlled trial which evaluated its Desyne BDS plus system, a triple drug-eluting coronary implant with site-specific antithrombotic therapeutic coating, against a contemporary, durable polymer drug-eluting stent in the treatment of de novo native coronary artery lesions.
Sino Medical Sciences Technology Inc. received marketing approval from China’s NMPA for its drug eluting stent system to improve vascular stenosis in patients with localized ischemic heart disease. The product is designed to improve the speed of wound healing and accelerate the recovery of vascular endothelium after stent implantation. It fits vessels with a diameter of 2.25 mm to 4.00 mm and a lesion length of less than or equal to 40 mm.
Following last week’s FDA approval of its Onyx Frontier drug eluting stent (DES), Medtronic plc released results at EuroPCR from a real-world, multicenter prospective study using its Resolute Onyx platform for percutaneous coronary interventions (PCI) in the left main artery. Rehovot, Israel-based Pi-Cardia Ltd. also released early data for patients treated with its Short Cut transcatheter device for coronary obstruction prevention.
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.
The controversy over the use of paclitaxel in devices for the peripheral vasculature has taken a significant bite out of sales, but a new study serves to help reverse the narrative regarding mortality. According to a study of more than 168,000 Medicare patients, stents and angioplasty balloons coated with paclitaxel (PTX) were non-inferior to non-coated devices for mortality out to nearly three years, a finding that may encourage clinicians to return to normal utilization patterns and thus help to restore sales volumes.
Boston Scientific Corp. has received the U.S. FDA’s nod for its Synergy Megatron drug-eluting stent (DES) system. The company said the premarket approval makes Synergy Megatron the first platform in the U.S. that is designed for large, proximal vessels. The Synergy Megatron biopolymer (BP) stent is indicated “for improving coronary artery luminal diameter in patients with symptomatic ischemic heart disease, stable or unstable angina, non-ST elevation myocardial infarction or documented silent ischemia due to atherosclerotic lesions in native coronary arteries.
The storm of controversy over the use of paclitaxel in devices for the peripheral vasculature had a dramatic effect on utilization, but a new study coming out of Sweden seems to have helped further ease concerns about purported mortality associated with this antiproliferative. While this unplanned interim analysis lends yet more support to the view that the mortality signal in the so-called Katsanos paper did not reflect a true biological finding, the net effect of the controversy has prompted a call for a registry that might eliminate some statistical noise that had a significant and harmful impact on patients.
The drug-eluting balloon (DEB) has not displaced the drug-eluting stent (DES) for treatment of infarcts, but that may be changing with the results of the PICCOLETO II study.
Medtronic plc’s winning streak continued this week with the announcement that the U.S. FDA had given its nod for new one-month of dual-antiplatelet therapy (DAPT) labeling with an expanded indication for high bleeding risk (HBR) patients implanted with the Resolute Onyx drug-eluting stent (DES). The approval is based on results from the Onyx ONE Clear Study that evaluated about 1,500 complex HBR patients on one-month DAPT treated with Resolute Onyx.
