Directional atherectomy before paclitaxel coated balloon angioplasty in complex femoropopliteal disease: The VIVA REALITY study.

Krishna J Rocha-Singh, Ravish Sachar, Brian G DeRubertis, Claus C A Nolte-Ernsting, John G Winscott, Prakash Krishnan, Eric C Scott, Lawrence A Garcia, Jean-Luc Baeriswyl, Gary Ansel, Kenneth Rosenfield, Thomas Zeller, ,

<h4>Background</h4>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.<h4>Objectives</h4>Assess the safety and effectiveness of a vessel preparation strategy with ...
