The Chocolate BAR study is a prospective multicenter post‐market registry designed to evaluate the safety and performance of the Chocolate percutaneous transluminal angioplasty balloon catheter in a broad population with symptomatic peripheral arterial disease. The primary endpoint is acute procedural success (defined as ≤30% residual stenosis without flow‐limiting dissection); secondary long‐term outcomes include freedom from target lesion revascularization (TLR), major unplanned amputation, survival, and patency. A total of 262 patients (290 femoropopliteal lesions) were enrolled at 30 US centers between 2012 and 2014. The primary endpoint of procedure success was achieved in 85.1% of cases, and freedom from stenting occurred in 93.1%. Bail out stenting by independent adjudication occurred in 1.6% of cases and there were no flow limiting dissections. There was mean improvement of 2.1 Rutherford classes (±1.5) at 12‐months, with 78.5% freedom from TLR, 97.2% freedom from major amputation, and 93.3% freedom from all‐cause mortality. Core Lab adjudicated patency was 64.1% at 12 months. Use of the Chocolate balloon in an “all‐comers” population achieved excellent procedural outcomes with low dissection rates and bailout stent use.
