Abstract

Aims: The usefulness of transesophageal echocardiographic (TEE) monitoring for transvenous lead extraction (TLE) procedures is still controversial. The purpose of the current study was to present new TEE values in detecting invisible events in fluoroscopy and preventing the development of dangerous complications.

Methods: From 2015 to 2019, a total of 1026 procedures were performed in single TLE center. In total, 1108 leads had been extracted with a mean lead dwell time of 115.8 ± 77.6 months. Continuous TEE was used in 936 patients with a mean age of 67.1 ± 14.4 years.

Results: Preprocedure examination revealed looped leads in 181 (19.3%) patients, dry cardiac perforation in 151 (16.1%), lead-to-lead adhesion in 172 (18.4%), lead adhesion to the myocardium in 317 (33.9%), and vegetations in 119 (12.7%) patients. Intra-procedural TEE demonstrated pulling on the atrial wall, ventricular wall, or tricuspid valve in 380 (40.5%), 235 (25.1%), and 78 (8.3%) patients, respectively. Acute tamponade requiring sternotomy occurred in 11 (1.1%) patients. Migration of vegetation or connective tissue fragments were seen in 69 (7.3%) and 111 (11.8%) patients, respectively. After procedure, TEE was helpful in navigating an implantation, a new lead in 97 (10.3%) patients, and removing the remnants of lead/silicone insulation in 50 (5.3%) patients.

Conclusion: Real time transesophageal echocardiography for the guidance of transvenous lead extraction informs the operator about the danger of manipulations close to delicate cardiac structures and whether immediate modification to the plan of lead removal is necessary in order to prevent the occurrence of unwanted events.
