   Tricuspid Regurgitation Study

   Location:

   Rochester, MN

   Trial status:

   Open for Enrollment

   Why is this study being done?

   Leads are commonly placed in the right ventricular apex. It is not known whether placing similar leads higher on the septum where there will be less redundancy or pressure on the septal leaflet will change the extent and severity of tricuspid regurgitation following pacemaker/ICD implantation. Data has shown that right ventricular pacing can give rise to right ventricular dysfunction, which in turn may give rise to enlargement of the right ventricle and cause tricuspid regurgitation. The study will answer the clinically relevant questions on device lead-related tricuspid regurgitation. This study is a single center prospective study at the Mayo Clinic, Rochester. The study will enroll 200 eligible subjects and follow for 12 months. 50 pacemaker subjects will be randomized to right ventricular apex pacing 50 pacemaker subjects will be randomized to right ventricular septum pacing 50 pacemaker subjects will be randomized to left ventricular pacing via coronary sinus 50 ICD subjects will be enrolled with right ventricular apex pacing. A baseline heart failure assessment and Two Dimensional echocardiography will be performed before device implant. A Two Dimensional echo will be performed 24 hours after device implant. If significance TR is present a Three Dimensional echo will be performed. At 12 months post implant heart failure assessment and Two Dimensional echo will be performed.
