    Abstract:
    BACKGROUND: Endocardial leads of permanent pacemakers (PPM) and implantable defibrillators (ICD) across the tricuspid valve (TV) can lead to tricuspid regurgitation (TR) or can worsen existing TR with subsequent severe morbidity and mortality. OBJECTIVES: To evaluate prospectively the efficacy of intraprocedural 2-dimentional-transthoracic echocardiography (2DTTE) in reducing/preventing lead-associated TR. METHODS: We conducted a prospective randomized controlled study comparing echocardiographic results in patients undergoing de-novo PPM/ICD implantation with intraprocedural echo-guided right ventricular (RV) lead placement (Group 1, n=56) versus non-echo guided implantation (Group 2, n=55). Lead position was changed if TR grade was more than baseline in Group 1. Cohort patients underwent 2DTTE at baseline and 3 and/or 6 months after implantation. Excluded were patients with baseline TR > moderate or baseline ≥ moderate RV dysfunction. RESULTS: The study comprised 111 patients (74.14 ± 11 years of age, 58.6% male, 19% ICD, 42% active leads). In 98 patients there was at least one follow-up echo. Two patients from Group 1 (3.6%) needed intraprocedural RV electrode repositioning. Four patients (3.5%, 2 from each group, all dual chamber PPM, 3 atrial fibrillation, 2 RV pacing > 40%, none with intraprocedural reposition) had TR deterioration during 6 months follow-up. One patient from Group 2 with baseline mild-moderate aortic regurgitation (AR) had worsening TR and AR within 3 months and underwent aortic valve replacement and TV repair. CONCLUSIONS: The rate of mechanically induced lead-associated TR is low; thus, a routine intraprocedural 2DTTE does not have a significant role in reducing/preventing it.
