Abstract

Cardiac implantable electronic devices (CIEDs) have been implicated in the development of tricuspid valve (TV) dysfunction. However, the mechanisms of dysfunction are not well characterized. We sought to define the prevalence, location and mechanisms of CIED-TV interference based on direct inspection of gross pathologic specimens from consecutive patients with CIEDs who had undergone orthotopic heart transplantation (OHT). CIED-interference was classified by location (septal, posterior or anterior trigone of the RV), portion of TV apparatus involved (leaflet(s) only, sub-tricuspid apparatus (STA) only or a combination of both leaflet and STA) and type of interference (adherence, trapping or both). Sixty-two cases of CIED-TV interference were identified (5 leaflet, 30 STA and 27 leaflet and STA). The majority of patients had non-ischemic cardiomyopathy (81%) and leads in situ for
