As cardiovascular patients live longer and undergo increasingly complex procedures, relying solely on mortality as benchmark of success is no longer sufficient. While patient-reported outcomes incorporate quality of life, symptoms, and functional status, they are often clinician-framed, lengthy, and difficult to integrate into routine care. Patient-defined outcomes is a patient-led evolution of this concept that emphasizes priorities such as autonomy and independence and avoiding outcomes deemed so undesirable that patients would sacrifice longevity to prevent them. Disability-free survival and patient-defined adverse cardiovascular and noncardiovascular events are composite patient-defined outcomes codeveloped with patients. Unlike patient-reported outcomes, which can be unwieldy, patient-defined outcomes are interpretable, autonomy-centered endpoints that extend beyond survival and traditional quality-of-life questionnaires. Integrating these measures into cardiac surgical and interventional workflows, especially during preoperative assessment and tailored optimization, helps align care with patient goals. Patient-defined outcomes have the potential to transform perioperative care by shifting the focus from living longer to living better.
