Monitoring of TLE procedure using TEE does it influences for procedure efficacy ? The comparison of two large populations (1058 and 2068 patients)

To improve safety of lead extraction monitoring by using continuous TEE was proposed and introduced recently (after the introduction of cardiac surgeon presence, optimal venue such as hybrid room, arterial line etc). However, until now it is not proved that it works in practice.

The goal of this study was to compare TLE effectiveness and safety between two large group with TLE performed with and without TEE monitoring.

During last 15 years 3126 TLE were performed; 5183 leads (1-6 leads, aver 1,65, with mean implant duration time 95,7 mth) were extracted using - as first line - non-powered mechanical tools.

In spite of the fact that the group which was monitored with TEE was sicker (Carlson’s index, lower EF), had more TLE risk factors (implant duration) and TLE procedure was much more difficult (more technical problems) – the TLE effectiveness was better (more radiological, clinical and procedural success, less partial radiological success) and major complications was even slightly less frequent. Unexpected differences in mid-term mortality can be explained by different rate of infective indications or lead remnant influence.

Results seem to indicate favourable effects of utility TEE for TLE procedure monitoring.
