Prognostic Value of Preoperative Echocardiographic Findings in Patients Undergoing Transvenous Lead Extraction.

ABSTRACT: (1) Background: In patients referred for transvenous lead extraction (TLE) transesophageal echocardiography (TEE) often reveals abnormalities related to chronically indwelling endocardial leads. The purpose of this study was to determine whether the results of pre-operative TEE might influence the long-term prognosis. (2) Methods: We analyzed data from 936 TEE examinations performed at a high volume center in patients referred for TLE from 2015 to 2019. The follow-up was 566.2 ± 224.5 days. (3) Results: Multivariate analysis of TEE parameters showed that vegetations (HR = 2.631 [1.738-3.983]; p < 0.001) and tricuspid valve (TV) dysfunction unrelated to the endocardial lead (HR = 1.481 [1.261-1.740]; p < 0.001) were associated with increased risk for long-term mortality.
