Stents Drug Eluting
This channel includes news and new technology innovations for drug eluting stents (DES). These drug coated stents were developed to solve a frequent problem with bare metal stents, which can cause neointimal hyperplasia (scar tissue growth) in some patients. The antiproliferative drugs used on DES prevent the growth of tissue. One downside of DES is the requirement for patients to take long-term antiplatelet therapy to prevent the possible formation of clots on these stents. Newer generation DES use technologies help the vessels heal faster, which may allow reduce the duration of dual antiplatelet therapy (DAPT), or use a single drug, usually eliminating aspirin. This section includes news for both metallic and bioresorbable drug-eluting stents and related clinical trial data.
The Boston Scientific Synergy stent uses a unique abluminal, bioresorbable drug-carrier polymer that dissolves after the vessel wall has healed months after the stent is implanted. Stent polymers have been implicated in cases of late-stent thrombosis, which required patients with DES to stay on dual antiplatelet therapy (DAPT). This study looked at using the device as a way to shorten DAPT duration.
EchoPixel showed technology at TCT 2019 that creates live holograms in the cath lab from 3-D TEE imaging. It projects the holograms on a special display screen that does not require the user to wear 3-D glasses. The interventional cardiologist can use hand movements and a foot switch to move the image around without breaking the sterile field. It offers a new way to visualize catheters, device positioning and deployment in structural heart procedures. (Photos by Dave Fornell)
