Abstract

Background: Transesophageal echocardiography (TEE) is commonly used during cardiothoracic procedures. TEE has also become standard during transvenous lead extraction (TLE) procedures, but its effect and role have not been optimally defined. The goal of this study is to identify how TEE was used during TLE at our institute and review its utility.

Methods: We retrospectively reviewed high-risk patients undergoing TLE, for whom more complications during extraction procedures, from June 2012 to September 2020. The patients were divided into TEE group and non-TEE group according to real-time TEE monitoring. We compared the rate of procedural success, complications between two groups and concluded the clinical utility of TEE during TLE.

Results: A total of 195 patients were included (105 in TEE group vs 90 in non-TEE group), the rate of procedure success (97.8% vs 96.5%, p = 0.41) and complications during extraction (8.6% vs 12.2%, p = 0.40, major complication 5.7% vs 12.2%, p = 0.11, minor complication 2.9% vs 0%, p = 0.30) were comparable. In TEE group, 12 patients (11.4%) received following benefits: altering surgical plans, guiding subsequent therapy strategies, and rapidly diagnosing complications, moreover no complications occurred from TEE.

Conclusions: This study demonstrates that real-time monitoring by TEE cannot change the rate of procedural success and complication during TLE; however, TEE provides valuable information to instruct clinical therapy and improves the safety of TLE.
