OBJECTIVES: The aim of this study was to compare the stroke/death rates between proximal embolic protection devices (P-EPDs) and distal filter embolic protection devices (F-EPDs) in elective carotid artery stenting (CAS).
BACKGROUND: P-EPDs have theoretical advantages that may make them superior to F-EPDs for stroke prevention during CAS.
METHODS: We examined 10,246 consecutive elective CAS procedures performed with embolic protection in the NCDR CARE registry between January 2009 and March 2013. We analyzed crude and propensity-matched rates of in-hospital combined death/stroke in patients treated with P-EPDs versus F-EPDs. Secondary analyses included 30-day adverse event rates and stroke rates by the involved cerebrovascular territory.
RESULTS: P-EPDs were used in 590 of 10,246 cases (5.8%). Patients treated with P-EPDs had higher rates of symptomatic lesion status (46.8% vs. 39.7%, p<0.001), atrial fibrillation/flutter (16.1% vs. 13.0%, p=0.03), and history of a neurological event (51.2% vs. 46.6%, p=0.03). In unadjusted and propensity-matched analyses, differences in in-hospital stroke/death between P-EPD and F-EPD cohorts were nonsignificant (1.5% vs. 2.4%, p=0.16 and 1.6% vs. 2.0%, p=0.56, respectively). For patients with available data (n=7,693, 75.1%), 30-day adverse events rates were similar for P-EPDs and F-EPDs before (2.5% vs. 4.2%, p=0.07) and after (2.7% vs. 4.0%, p=0.22) propensity matching.
CONCLUSIONS: Use of a P-EPD during CAS was associated with low rates of in-hospital stroke/death similar to those with an F-EPD in the first comparative effectiveness study of the devices. An adequately powered randomized trial comparing clinical outcomes between these devices is unlikely to be feasible.
