January 2, 2018—Tesfaldet T. Michael, MD, et al reported the 9-month results of the BIOHELIX-I[1] clinical trial that evaluated the bare-metal Pro-Kinetic Energy (PKE) cobalt chromium coronary stent system (Biotronik). The findings are available online in Catheterization and Cardiovascular Interventions[2].

In the background notes to the study, the investigators advised that although drug-eluting stents constitute a majority of implants, bare-metal stents (BMSs) remain important for a subset of patients as newer-generation BMSs offer advantages with stent design improvements.

As summarized in Catheterization and Cardiovascular Interventions, the BIOHELIX-I study is a prospective, multicenter, nonrandomized, single-arm clinical trial designed to evaluate the safety and efficacy of the PKE BMS. Thirty-three study centers in the United States, Columbia, and Europe enrolled 329 patient...
