Radiation use in electrophysiology procedures may have detrimental health impacts to patients as well as being a key occupational hazard for catheter laboratory staff, both from direct effects as well as orthopaedic injuries from heavy lead aprons. Use should be kept as low as reasonably possible (ALARA principle). Advances in 3D electroanatomical mapping systems have greatly reduced the reliance on fluoroscopy for complex electrophysiology procedures. After ultrasound guided femoral venous access a decapolar catheter and electroanatomical mapping system was used to create an anatomic shell from femoral vein to right atrium and superior vena cava. Using this map catheters were then placed in the coronary sinus, HIS and right ventricular apex positions. Where transseptal puncture was required alligator clip electrodes were used to visualise the wire/needle along with intracardiac echo guidance. 5 consecutive patients (aged 15-60) referred to a single operator at our centre for supraventricular tachycardia ablation underwent planned zero fluoroscopy procedures (1 no inducible tachycardia diagnostic study only, 1 AV-nodal reentrant tachycardia, 2 left-sided accessory pathways, 1 coronary sinus os atrial tachycardia). The ablation procedures were successful with no procedural complications. No cases required fluoroscopic screening (Mean X-ray time: 0 minutes, Mean DAP: 0μGym2). Mean procedure time was 160.2 minutes (range: 101 - 211 minutes). Following the second case staff other than the primary operator did not wear lead aprons. Our early experience demonstrates the feasibility of performing right and left sided ablations without fluoroscopy in an Australian setting.
