Abstract
BACKGROUND: Drug coated balloon (DCB) angioplasty significantly reduces reintervention rates in patients with symptomatic femoropopliteal peripheral artery disease (PAD). However, stand-alone DCB use in long, severely calcified lesions is frequently associated with vessel recoil and/or high-grade dissections necessitating provisional stent implantation.
OBJECTIVES: Assess the safety and effectiveness of a vessel preparation strategy with directional atherectomy (DA) prior to DCB angioplasty in patients with symptomatic severely calcified femoropopliteal PAD.
METHODS: REALITY (NCT02850107) prospectively enrolled subjects at 13 multinational centers with 8-36 cm femoropopliteal stenoses or occlusions with bilateral vessel wall calcification treated with DA prior to DCB angioplasty. The primary effectiveness endpoint was 12-month primary patency, and the primary safety endpoint was freedom from major adverse events through 30 days. Independent angiographic and duplex core laboratories assessed outcomes and a Clinical Events Committee adjudicated events.
RESULTS: A total of 102 subjects were enrolled; one lesion was treated per subject. The mean lesion length was 17.9 ± 8.1 cm, 39.0% were chronic total occlusions (mean lesion length 22.6 ± 8.6 cm); 86.2% of lesions exhibited moderate to severe bilateral calcification. Provisional stents were implanted in 8.8% (9/102) of subjects. Twelve-month primary patency rate was 76.7% (66/86) and freedom from CD-TLR rate was 92.6% (87/94). No device or procedure related deaths and one index-limb major amputation were reported.
CONCLUSIONS: Plaque excision with DA in patients with symptomatic severely calcified femoropopliteal arterial disease prior to DCB angioplasty is a safe and effective treatment strategy with a low provisional stent rate.
