    Extensive Preferential Pathway Ablation for the Elimination of Premature Ventricular Contractions Arising from the Right Ventricular Outflow Tract

    A 76 y/o women presented with 2 different types of premature ventricular contractions (VPCs 1 and 2) arising from the right ventricular outflow tract (RVOT). Catheter ablation (CA) eliminated PVC1 at the earliest activation site (EAS), but thereafter another PVC morphology (PVC3) appeared. Small potentials preceding the local potential were broadly exhibited from the RVOT’s supero-anterior region to the EAS during PVC3. Point CA targeting such prepotentials failed. Transverse-linear CA with a line connecting sites with such pre-potentials eliminated both PVCs 3 and 2. In cases with broadly spreading preferential pathways, extensive CA might be needed to eliminate the PVCs

    Fabry cardiomyopathy presenting with a high defibrillation threshold: A short case report

    Fabry disease is an X-linked recessive glycosphingolipid storage disorder caused by a deficiency of lysosomal enzyme α-galactosidase A. It is recognized that Fabry disease patients often have ventricular arrhythmias. Although the effectiveness of implantable cardioverter-defibrillator (ICD) therapy in patients with ventricular fibrillation is established, there is little evidence regarding ICD therapy for Fabry disease. Here, we report the case of patient with Fabry disease who was treated with an ICD and presented with high defibrillation thresholds
