Abstract
Introduction
Transvenous leads extraction (TLE) of permanently implanted coronary sinus (CS) leads is widely believed to present greater risks than the removal of other leads.
Aim
To assess the safety and efficacy of CS leads extraction based on large research material obtained by one operator performing procedures in two TLE centres.
Material and methods
We extracted 408 CS leads from 389 patients, and the results were compared to a control group of 2465 patients who underwent non-CS lead TLE procedures.
Results
There were no significant differences in the clinical success rate (97.9% vs. 98.0%) or the major complication rate (2.1% vs. 1.8%) between the CS and control group. CS lead destination (LV/LA pacing) and tip location (CS ostium/mid CS /CS tributaries) influenced the procedural and radiological success rates and procedural complexity but not the complications. CS lead extraction did not affect the necessity for a cardiosurgical intervention or presence of procedure-related death.
Conclusions
TLE of CS leads can be achieved with a high procedural success rate. The major complication rate is not higher than that seen in non-CS lead extraction patients. More than half of CS leads cannot be removed by simple traction and the use of mechanical sheaths may be necessary. The detachment of CS leads from connective tissue scars in the venous and atrial areas up to the CS ostium is generally sufficient for further removal of the lead using simple traction.
