Key result
Radiofrequency catheter ablation of frequent premature ventricular complexes eliminated the arrhythmia and rapidly improved clinical status and echo parameters in a CRT non-responder.
Why the study?
Does radiofrequency catheter ablation of PVCs improve left ventricular function in a CRT non-responder?
Case Report (n=1)
Does radiofrequency catheter ablation of PVCs improve left ventricular function in a CRT non-responder?
Frequent PVCs may be an underrecognized cause of CRT non-response, and radiofrequency ablation can improve clinical and echocardiographic outcomes in these patients.
No takes yet. Share an insight, caveat, or question.
Prompts PVC assessment in CRT non-responders; hypothesis-generating and requires prospective validation before practice change.
Herczku et al. (2007) conducted a case report in Severe congestive cardiomyopathy non-responsive to cardiac resynchronization therapy (n=1). Radiofrequency catheter ablation was evaluated on Arrhythmia elimination, clinical status, and echocardiographic parameters. Radiofrequency catheter ablation of frequent premature ventricular complexes eliminated the arrhythmia and rapidly improved clinical status and echo parameters in a CRT non-responder.
