“Cardiac Resynchronization Therapy (CRT) has proven to decrease the mortality and morbidity in patients diagnosed with heart failure. Many patients implanted with a CRT device will experience an improved quality of life. Unfortunately, not all patients implanted with a CRT device will respond to the therapy though. These patients are often referred to as “non-responders”.
– Are there specific reasons why a patient may not respond to CRT? Anything to do with the patient’s pre-implant clinical presentation or the implant technique?
– How do we know if patient hasn’t responded to CRT? Are there clinical markers? Patient symptoms?
– Can anything be done post-implant to improve the outcome of a patient that is demonstrating non-response to CRT?
