Of the numerous non-surgical therapies available to treat ventricular tachycardia (VT), catheter ablation is the least practised but has great promise for increased use in the treatment of this difficult arrhythmia. The paper by Furniss and colleagues1 in this issue of Heart describes the successful application of catheter ablation to a population of patients hitherto regarded as being virtually untreatable in this way; those whose arrhythmia leads quickly to collapse. Is their experience reproducible? If so, does it represent a new limit for the technique or does it offer a glimmer of hope that all ventricular tachyarrhythmias, including ventricular fibrillation, might be treatable by catheter ablation?
Catheter ablation has become the treatment of choice for most
supraventricular tachycardias (SVTs) with the sole exception, for the
moment, of atrial fibrillation. This has occurred because of the
treatment's efficacy (a success rate of at least 90%) and safety.
