Key result
Three-dimensional mapping revealed an arrhythmic substrate missed at initial diagnosis in a patient with idiopathic ventricular fibrillation 12 years later.
Why the study?
Management of idiopathic ventricular fibrillation is challenging because an arrhythmic substrate may be missed at initial diagnosis, necessitating careful follow-up and reassessment.
Three-dimensional mapping may be a useful tool for the reassessment of patients with idiopathic ventricular fibrillation to identify previously missed arrhythmic substrates.
May support long-term reassessment of idiopathic VF with 3D mapping; hypothesis-generating and requires prospective validation before practice change.
Management of idiopathic ventricular fibrillation (IVF) is challenging because an arrhythmic substrate may be missed at initial diagnosis; therefore, careful follow-up and reassessment are necessary. Three-dimensional mapping would be useful for reassessment of IVF because it revealed an arrhythmic substrate in a patient, 12 years after his initial IVF diagnosis. .
