The role of transesophageal echocardiography in predicting technical problems and complications of transvenous lead extractions procedures.

ABSTRACT:

Background

Transesophageal echocardiography (TEE) is a useful tool in preoperative evaluation of patients undergoing transvenous lead extraction (TLE).

Hypothesis

Echocardiographic phenomena may determine the difficulty and safety of the procedure.

Methods

Data from 936 transesophageal examinations (TEE) performed at a high volume center in patients awaiting TLE from 2015 to 2019 were assessed.

Results

TEE revealed a total of 1156 phenomena associated with the implanted leads in 697 (64.85%) patients, including: asymptomatic masses on endocardial leads (AMEL) (58.65%), vegetations (12,73%), fibrous tissue binding the lead to the vein or heart wall (33.76%), lead-to-lead binding sites (18.38%), excess lead loops (19.34%), intramural penetration of the lead tip (
