    Abstract:
    OBJECTIVES: The objective of this study was to examine the effect of laser lead extraction (LLE) on the development of post-procedural tricuspid regurgitation (TR). Some reports have suggested an increase in TR associated with LLE. We present a series of patients who underwent both, LLE and complete echocardiographic evaluation for TR. METHODS: A single centre analysis of consecutive patients referred for LLE between January 2012 and August 2015. One hundred and three patients had tricuspid valve function evaluated before the procedure with a transthoracic echocardiography (TTE), during the procedure using transoesophageal echocardiography and postoperatively using a TTE. TR was graded from 0 (none) to 4 (severe). RESULTS: We treated 235 leads in 103 patients, including 118 ventricular leads. Seventy-seven were male (74.8%) and 26 female (25.2%), with a mean age of 65.6 ± 15.4 years. Mean time from initial lead implantation was 98.0 ± 67.3 months. Twenty-one patients (20.4%) had ejection fraction below 30%. No intra-procedural worsening of tricuspid valve function was seen with TEE in any of the patients. Ten patients (9.7%) were found to have TR before LLE that returned to normal valve function after the procedure. Two patients (1.9%) experienced mild TR after the procedure (both with tricuspid valve endocarditis). Ninety-one patients (88.3%) did not experience any significant change of the tricuspid valve function after LLE. CONCLUSION: Transthoracic and transoesophageal echocardiography findings showed that laser lead extraction was not associated with a significant increase in the incidence of tricuspid valve regurgitation.
