Objective  Complete extraction the cardiac implantable electronic devices (CIED) lead systems remains a complex procedure .This rerospective study was conducted to describe the safety and effectiveness of a modified extracting transvenous lead technique.

Methods The purpose of this study was to determine the effectiveness and safety for modified extraction of transvenous lead techniques by ablation catheter.

Results  Total 151 patients, 97 males and 54 females, with CIED related infections were retrospective enrolled in this study. There were 75 patients with CIED lead extraction using standard techniques and equipment, the other 76 patients with CIED lead extraction using a modified extraction transvenous lead techniques. There were no significant differences in the age, gender, NYHA functional class in two groups. The lead extraction time, procedure time and fluoroscopy exposure time shows  significant reduction (lead extraction time from 33±8 min to 22±7 min, p< 0.001; procedure time from 64±18 min to 47 ± 19 min, p < 0.001 and fluorocopy exposure time from 36±7 min to 24±6 min. p<0.001). There was significant improvement in cumulative successive rate of lead extraction from 69 of 75 (92%) patients by using the standard technique and equipments, to 73 of 76 (96.1%) patients by the modified extraction of transvenous lead techniques. (P=0.03)

Conclusion  It is effective and safe  extraction CIED lead through femoral approach by  the modified extraction of  transvenous lead techniques for ablation catheter.
