Feb 24, 2021 Making TCAR available for select patients leads to 10% lower MACE rates Hospitals that adopted transcarotid artery revascularization (TCAR) as an option for carotid revascularization saw a 10% reduction in perioperative major adverse cardiovascular events (MACE) in patients with carotid artery stenosis, according to a registry-based study, although other quality-of-care initiatives may also have played a part. In a study of data from the Society of Vascular Surgery’s Vascular Quality Initiative (VQI), the crude rate of MACE was similar for post-TCAR and post-CEA at 2.3% versus 2.4% ( P=0.91), reported Jesse A. Columbo MD, MS, of the Dartmouth-Hitchcock Medical Center in Lebanon, New Hampshire, and co-authors.
