Abstract
BACKGROUND: The high rate of periprocedural complications resulting from atherothrombotic embolization after percutaneous intervention in diseased saphenous vein grafts is reduced by distal microcirculatory protection using a balloon occlusion and aspiration system. Whether filter-based catheters, which offer the inherent advantages of maintained perfusion and ease of use, are as effective for this purpose has not been established.
METHODS AND RESULTS: A total of 651 patients undergoing percutaneous intervention of 682 saphenous vein graft lesions were prospectively randomized to distal protection with the filter-based FilterWire EX versus the GuardWire balloon occlusion and aspiration system. Device success was 95.5% and 97.2% with the FilterWire EX and GuardWire, respectively (P=0.25). Postprocedural measures of epicardial flow and angiographic complications were similar between the 2 groups, although bailout IIb/IIIa inhibitors were required slightly less frequently in the FilterWire EX group (0% versus 1.5%, P=0.03). The primary end point, the composite incidence of death, myocardial infarction, or target vessel revascularization at 30 days, occurred in 9.9% of FilterWire EX patients and 11.6% of GuardWire patients (difference [95% CI]=-1.7% [-6.4%, 3.1%]; P for superiority=0.53, P for noninferiority=0.0008).
CONCLUSIONS: Distal protection with the FilterWire EX may be safely used as an adjunct to percutaneous intervention of diseased saphenous vein grafts and, compared with distal protection with the GuardWire balloon occlusion and aspiration system, results in similar rates of major adverse cardiac events at 30 days.
