Transvenous Lead Extraction in Patients with Congenital Heart Disease

Area of Science:

• Cardiology
• Electrophysiology
• Congenital Heart Disease

Background:

• Congenital heart disease (CHD) patients often require transvenous pacemaker (PM) or implantable cardioverter defibrillator (ICD) leads.
• Lead extraction (TLE) is a necessary procedure for a subset of these patients.
• The use of advanced tools like powered mechanical sheaths in TLE for CHD patients warrants investigation.

Purpose of the Study:

• To evaluate the outcomes and complexity of transvenous lead extraction (TLE) in congenital heart disease (CHD) patients.
• To specifically assess the efficacy and safety of using powered mechanical sheaths in TLE for CHD patients.

Main Methods:

• Retrospective analysis of 175 consecutive TLE procedures.
• Comparison of 13 TLEs in CHD patients versus 162 TLEs in non-CHD patients.
• Data collected on patient demographics, lead characteristics, procedural success, and complications.

Main Results:

• CHD patients were younger at lead implantation and extraction compared to non-CHD patients.
• Leads extracted from CHD patients were significantly older than those from non-CHD patients.
• Procedural success (92% vs. 87%), clinical success (100% vs. 91%), and complication rates (0% vs. 11%) were comparable between groups.
• Rotational mechanical sheaths were used in 61% of CHD extractions versus 38% of non-CHD extractions without significant difference in outcomes.

Conclusions:

• Transvenous lead extraction using rotational mechanical sheaths is a safe and effective advanced technique for CHD patients.
• The outcomes and complexity of TLE in CHD patients are comparable to those in non-CHD patients.
• Powered mechanical sheaths facilitate successful TLE in this specialized patient population.
