Mid-term clinical and echocardiographic evaluation of super responders with and without pacing: the preliminary results of a prospective, randomized, single-centre study

AimsSuper response to cardiac resynchronization therapy (CRT) is related to excellent long-term prognosis. However, it is not known whether super responders (SRs) are in remission or have made a complete recovery. In other words, is CRT a destination therapy or a bridge to recovery? The objective was to assess the evolution of the clinical and echocardiographic data of SRs without pacemaker activity at the mid-term follow-up.
