In the article by Tomaiko-Clark et al. article [1] in the January 2022 issue, an error was made in regard to the design specifications of the Boston Scientific POLARx balloon. The POLARx balloon is pressurized to a constant 2.5 psi through inflation and ablation. In comparing the Medtronic FlexCath sheath and Boston Scientific POLARSheath, the outer diameter of the FlexCath is actually 15 Fr. The authors would like to apologize for these errors.
