Prevalence and prognostic impact of tricuspid regurgitation in patients with cardiac implantable electronic devices

Prevalence and prognostic impact of tricuspid regurgitation in patients with cardiac implantable electronic devices: From the national echocardiography database of Australia

The prevalence and prognostic impact of tricuspid regurgitation (TR) in patients with a cardiac implantable electronic devices (CIEDs) is not well understood. This month in IJC [1] we published the results of the largest retrospective study on the subject to-date using the National Echo Database of Australia (NEDA). We found that moderate or greater TR is prevalent (23.8%) and 2-fold greater than in those without devices. Furthermore, moderate and severe CIED-associated TR was associated with a 1.6 to 2.5-fold increase in all-cause mortality. The association of CIED-related TR with a poor prognosis was also especially pertinent in younger individuals. With an ageing population and expanding indications for life-saving device-therapy, these findings highlight the need for close follow-up of patients with device therapies and for clinicians to be cognisant of the potential adverse consequences of CIED-associated TR.
