Expanding opportunities to understand quality and outcomes of peripheral vascular interventions: The ACC NCDR PVI Registry

Lower extremity peripheral artery disease (PAD) and cerebrovascular disease (CeVD) are prevalent conditions in the United States, and both are associated with significant morbidity (eg, stroke, myocardial infarction, and limb loss) and increased mortality. With a growth in invasive procedures for PAD and CeVD, this demands a more clear responsibility and introduces an opportunity to study how patients are treated and evaluate associated outcomes. The American College of Cardiology (ACC) National Cardiovascular Data Registry (NCDR) Peripheral Vascular Intervention (PVI) Registry is a prospective, independent collection of data elements from individual patients at participating centers, and it is a natural extension of the already robust NCDR infrastructure. As of September 20, 2018, data have been collected on 45,316 lower extremity PVIs, 12,417 carotid artery stenting procedures, and 11,027 carotid endarterectomy procedures at 208 centers in the United States. The purpose of the present report is to describe the patient and procedural characteristics of the overall cohort and the methods used to design and implement the registry. In collecting these data, ACC and ACC PVI Registry have the opportunity to play a pivotal role in scientific evidence generation, medical device surveillance, and creation of best practices for PVI and carotid artery revascularization.
