Brief summary
We will conduct a two-centre randomised control study designed to assess the impact of transesophageal (TOE)- guided lead placement on the development of new or worsening tricuspid regurgitation (TR). All eligible patients will have a TOE at the time of randomisation, as an exclusion criteria is inadequate TOE images. In the treatment arm, the implanter will be guided by the images obtained on the TOE in order to place the lead in a favourable commissural position so as to minimise tricuspid regurgitation. In the control arm, the implanter will be blinded to the findings on TOE and use fluoroscopy to guide lead placement as is standard practice. The projected duration of the study is 2 years and it is expected that we will enrol 125 patients during this period who require the implantation of a pacemaker (PPM) or automated implantable cardioverter-defibrillator (AICD) as deemed clinically appropriate by their treating cardiologist. The follow-up to assess the primary and secondary endpoints after lead implantation will be at 6-months during a routine clinical follow-up with the treating specialist
Interventions
Intervention - Pacemaker or defibrillator lead manipulation (by treating proceduralist) under transesophageal echo guidance to ensure the lead is in a commissural position so as to minimise tricuspid regurgitation. - Approximate duration of procedure: Approximately 10 minutes will be added to the routine procedural time for device implantation, to allow for performance of transesophageal echo in all patients. In addition, a maximum of 8 minutes will be allowed for lead manipulation via echo-guidance in the treatment group. - Device-lead manipulation will be performed by the treating electrophysiologist. Transesophageal echo will be performed by a cardiac anaethsetist or cardiologist who is part of the research team (who is not the patients treating physician). - Monitoring for adherence to intervention not required (TOE-guided device-lead manipulation performed during pacemaker/defibrillator implantation)
