Assessing the effectiveness of lead extraction in patients with implantable electronic devices: the largest retrospective study in Mexico.

BACKGROUND

The use of cardiac implantable electronic devices (CIEDs) has increased in the past decade and increasing of associated complications. While infection is the most common indication for lead extraction, other reasons also necessitate the procedure.

OBJECTIVE

Evaluate the outcomes of transvenous lead extraction (TLE) procedures conducted in tertiary referral hospitals in Mexico.

MATERIAL AND

METHODS

This retrospective observational study included data from two centers in Mexico City, collected between November 2014 and October 2023. Patients who underwent TLE for indications related to pacemakers, implantable cardioverter-defibrillators (ICDs), or cardiac resynchronization therapy with defibrillator (CRT-D) were included. Primary outcomes assessed were procedure success rate, complications, and reasons for extraction.

RESULTS

The study analyzed 271 patients who underwent TLE, successfully removing 534 leads with an overall success rate of 97.4%. Major complications were reported in four patients.

CONCLUSIONS

Transvenous lead extraction is a highly effective therapeutic approach with a high success rate and low complication incidence in a large patient cohort.
