Right ventricle pacing lead effect on Tricuspid valve

Makoto Saito, Andrea Iannaccone, Gerry Kaye, Kazuaki Negishi, Wojciech Kosmala, Thomas H Marwick
Right ventricular (RV) pacing has been linked with lead-induced tricuspid regurgitation (TR), left ventricular (LV) dysfunction, and dyssynchrony, but the effect of pacing on RV function is unclear. We sought to investigate the effect of pacing on RV synchrony, RV function, and TR, and their association with LV function. In this substudy of the PROTECT-PACE (Protection of left ventricular function during right ventricular pacing) study of the effects of RV pacing in patients with preserved ejection fraction, 145 patients (76 RV apex and 69 non-RV apex pacing) had measurable RV parameters...

AIMS: The severity of tricuspid regurgitation (TR) is a predictor of outcome among heart failure patients. The interaction between cardiac resynchronization therapy (CRT) and TR has not been described. In this study, we examined the effect of pre-implant TR, and worsened TR post-implant, on response to CRT and overall survival. METHODS AND RESULTS: We included all patients with successfully implanted CRT systems between 2007 and 2010. Patients were divided into two groups pre-implant: (Gp 1) no-or-mild TR; and (Gp 2) moderate-or-severe TR...

While for decades right ventricular (RV) apical pacing has been the standard of care for patients requiring pacemaker or defibrillator lead placement, investigators have sought alternatives to achieve more physiologic electrical activation of the heart and reduce long-term pathologic effects of nonphysiologic apical pacing. These investigations have included attempts at identifying superior pacing sites within the right atrium and RV and development of new leads to enhance specificity of sensing and capture...

INTRODUCTION: In patients treated with permanent pacing, the electrode is typically placed in the right ventricular apex (RVA). Published data indicate that such electrode placement leads to an unfavourable ventricular depolarization pattern, while right ventricular outflow tract (RVOT) pacing seems to be more physiological. AIM: To compare long-term effects of RVOT versus RVA pacing on clinical status, left ventricular (LV) function, and the degree of atrioventricular valve regurgitation...
