RESUMO

BACKGROUND: Electroanatomical mapping systems (EMS) reduce fluoroscopy dose for the ablation. Higher costs and longer procedure times are the drawbacks associated with EMS. Our objective was to validate the efficiency of the EMS. OBJECTIVE: To demonstrate that using EMS is more efficient and as secure as the traditional system of ablation. METHODS: From April 2013 to June 2018, all patients were included into two groups, according to the intention of ablation with or without fluoroscopy. Right, left, supraventricular and ventricular ablation were included. We compared procedure variables (fluoroscopy, radiofrequency and procedure times, ablation results, complication rates and costs of the procedure) that included material and detrimental effect of fluoroscopy. RESULTS: A total of 105 were included in the fluoroscopy group and 287 in the without fluoroscopy group. We found an important reduction in time and radiation dose in all the ablation procedures studied, without increasing the procedure time. No differences in ablation results nor complications rate were found. We found lower costs in the flutter ablation without fluoroscopy, similar costs in the right focal tachycardia ablation group and higher costs in the without fluoroscopy group for the AVNRT and left accessory pathway. When detrimental effect of fluoroscopy was added, all procedures without fluoroscopy were significantly more efficient than the ones performed with it. CONCLUSIONS: Ablation without fluoroscopy is a technique as safe and effective as the conventional technique. Our study suggests that the radiation dose delivered to the patient and staff might be reduced, without increasing the total procedure time, being even more efficient.

RESUMO

Ionizing radiation is one of the main risks affecting healthcare workers and patients worldwide. Special attention has to be paid to medical staff in the vicinity of radiological equipment or patients undergoing radioisotope procedures. To measure radiation values, traditional area meters are strategically placed in hospitals and personal dosimeters are worn by workers. However, important drawbacks inherent to these systems in terms of cost, detection precision, real time data processing, flexibility, and so on, have been detected and carefully detailed. To overcome these inconveniences, a low cost, open-source, portable radiation measurement system is proposed. The goal is to deploy devices integrating a commercial Geiger-Muller (GM) detector to capture radiation doses in real time and to wirelessly dispatch them to a remote database where the radiation values are stored. Medical staff will be able to check the accumulated doses first hand, as well as other statistics related to radiation by means of a smartphone application. Finally, the device is certified by an accredited calibration center, to later validate the entire system in a hospital environment.
