-
Drug-coated balloons versus drug-eluting stents for chronic total occlusion of coronary arteries
This will test whether using drug-coated balloons (alone or with a stent when needed) works as well as drug-eluting stents alone for people whose chronically blocked coronary artery has been successfully opened.
-
Using intracoronary imaging more often to improve outcomes of complex coronary stenting
This project tests whether more frequent use of intracoronary imaging during complex stenting procedures for adults with complicated coronary artery disease leads to better stent results and fewer major complications.
-
FAPI PET/CT to predict adverse cardiac events after PCI for chronic total occlusion
This will test whether FAPI PET/CT scans done before PCI can help predict major heart problems within 12 months in adults with chronic total coronary occlusion.
-
Research on treating blocked coronary arteries in Taiwan
This study looks at different ways to treat blocked coronary arteries to see how well they work for people with chronic total occlusions.
