Transplant‐free survival based on peak oxygen consumption (VO 2) (A) and ventilatory efficiency (Ve/VCO 2 slope) (B). Comparison of survival curves for patients with arrhythmogenic right ventricular cardiomyopathy/dysplasia undergoing cardiopulmonary exercise testing based on peak VO 2 (≤14 vs >14 mL/kg per minute) and Ve/VCO 2 slope (≤34 vs >34). HR indicates hazard ratio.
