RESUMO
Ablation of sinus node reentrant tachycardia (SNRT) may be difficult with risk of sinus node injury by using conventional catheters. We report successful ablation of SNRT by using remote magnetic navigation system (Stereotaxis).

Placement of a dialysis catheter substantially increases the risk of central vein stenosis. 52-year-old female with end-stage renal disease and a right brachial-cephalic hemodialysis access presented with right arm swelling. The chronic total occlusion of right brachiocephalic vein was refractory to wire traversal. Sharp recanalization of the central venous occlusion was done with transseptal needle retrogradely. The track was balloon dilated and stented. When the conventional catheters and guide wires options fail, sharp recanalization technique may be used to salvage a precious dialysis access.
