Abstract
W e have used for this implant, 5 leads from 2 different producers: 2187 (16 pts), 4189 (18 pts), 4191 (25 pts) and 4193 (15 pts) from Medtronic and 4512 (48 pts) from Guidmt. As a parameter of better handl ing we have considered a reduced fluoro-time for the positioning of the LV lead. W e have made comparison in fluoro-time for each lead and dividing the 5 leads in two group: stylet-guided leads (4189 and 2187) and angioplasty-wire guided leads (4191,4193 and 4512). W e have not found any significant differences in fluoro-time nor for any of the considered leads neither for each group of leads. W e have also analysed if fluoro-time was related to single operator experience or to Centre experience. W e have found out that the longer the patient follow-up the longer the fluoro-time and the greater the number of patients implanted by the single operator the shorter the fluoro-time. In conclusion, OUT data seem to demonstrate that all the leads available on the market have the same good handl ing and that-once the operator has gained a good experience in such an intervention the mean fluoro-time required to position all the leads could be reduced to acceptable values.
