Abstract 16846: Tricuspid Insufficiency After Laser Lead Extraction
Background The use of laser lead extraction (LLE) to remove pacemaker (PCM) and implantable cardiac defibrillator (ICD) leads has become more prevalent in the past decade. Though the procedure is associated with a low level of complications, LLE still poses some risks to patients. Some reports have suggested an increase in Tricuspid Insufficiency (TI) associated with LLE. We present a series of patients who underwent both LLE and complete evaluation for TI with echocardiographic techniques.
Methods From August 2008 through January 2010, 173 prospective, consecutive patients underwent LLE in a single center. All patients had transesophageal echocardiograms (TEE) during the extraction. 53 patients had tricuspid valve function evaluated a day prior to the procedure with a transthoracic echocardiogram (TTE), during the procedure with a TEE and 2 days postoperatively with a TTE. Descriptive analysis of the data was performed. All echocardiography data was analyzed by a cardiologist specialized in cardiac echocardiograms.
Results All 173 patients experienced no change in tricuspid valve function during the procedure with TEE. 53 patients had complete TI evaluation, 38 males (72%), 15 females (38%), and a mean age of 69.45±14.08. Mean ejection fraction was 35.82±14.72. 3 (6%) patients experienced tricuspid insufficiency after the procedure (2 mild and 1 severe, all with device endocarditis); 16 (30%) patients were found to have TI before LLE that returned to normal valve function during or after the procedure. 34 (64%) patients did not experience any significant change of the tricuspid valve performance after LLE.
Conclusions Laser lead extraction was not associated with increased TI.
