Key result
CRT improves refractory congestive heart failure, though a significant subset of patients remains unresponsive.
Why the study?
Despite technical advances, a significant number of patients with refractory congestive heart failure remain unresponsive to cardiac resynchronization therapy.
This review provides an overview of cardiac resynchronization therapy for refractory congestive heart failure, highlighting unresolved issues and ongoing research regarding non-responders.

CRT non-response in refractory HF remains unresolved; leaves open research on refined selection and adjunct strategies.
Cardiac resynchronization therapy (CRT) has gained acceptance as a useful form of device therapy for patients with refractory congestive heart failure. Despite recent technical advances, a significant number of patients continue to remain unresponsive to this form of therapy. This article provides an overview of CRT, highlights several unresolved issues and describes ongoing research efforts to address some of these important questions.
