Summary:Cardiac resynchronization therapy (CRT) emerged as a therapeutic modality for patients with cardiac insufficiency (CI) refractory to pharmacological treatment. Over the last 20 years, several clinical studies have sought to establish their benefits in different populations. The review of the results of these studies has shown that in patients with advanced CI (functional class (FC) I, II, III and IV of the New York Heart Association (NYHA) CRT produces consistent improvements in quality of life, FC and exercise capacity, as well as reducing hospitalizations and mortality rates. Up to 70% of patients submitted to CRT evolve as responders. The criteria adopted in the evaluation of the CRT response rate will be elucidated in this article, in which the main objective is to highlight the concept of the CRT super-responder.
