Atrial Fibrillation Clinical Trial
Official title:
Multi-catheter Cryotherapy Versus Radiofrequency Catheter Ablation for the Treatment of Standard and Resistant Arrhythmias
A program of research has been set up at St. George's Hospital, London studyng the practicalities of catheter ablation. The current practice of catheter ablation is being studied for a range of arrhythmias including PAF, persistent AF, advanced persistent AF and resistant WPW.
The study design will be a separate randomised clinical trial for each of the arrhythmias
studied. There will be 1:1 randomisation to either the cryotherapy protocol or RF protocol.
Arrhythmia patients already under the care of this cardiac centre, who have already opted for
catheter ablation treatment will be approached to ask if they will also be willing to
participate in this longterm research program.
The protocols for each different arrhythmia are in line with current practice and knowledge
and utilising current technology. In the program, the investigators have 1 or 2 protocols
that mildly differ from conventional use but have already passed through initial experience
with publication on this- this is the multi-catheter cryocatheter approach.
Acute procedural outcomes, short, medium and longterm success will be recorded for each
patient, in addition to patient or participant experience and quality of life outcomes.
The catheter ablation research program has passed through ethical panel review in London and
has the potential to become a multi-centre study.
