Key result
Three-dimensional mapping successfully identified a previously missed arrhythmic substrate in a patient 12 years after an initial diagnosis of idiopathic ventricular fibrillation.
Why the study?
Management of idiopathic ventricular fibrillation is challenging because arrhythmic substrate may be missed, requiring careful follow-up and reassessment.
Does three-dimensional mapping improve the detection of arrhythmic substrate in patients with idiopathic ventricular fibrillation?
Does three-dimensional mapping improve the detection of arrhythmic substrate in patients with idiopathic ventricular fibrillation?
Three-dimensional mapping may be a useful tool for the reassessment and identification of previously missed arrhythmic substrates in patients with idiopathic ventricular fibrillation.
May support 3D mapping for late IVF reassessment; hypothesis-generating and should not yet change practice.
Management of idiopathic ventricular fibrillation (IVF) is challenging because arrhythmic substrate may be missed; 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 diagnosis of IVF.
