Leadless pacemakers, specifically Micra (Medtronic), have recently become a preferred alternative to transvenous pacemakers for use in bradyarrhythmia. Problems with conventional transvenous pacemakers include wound infection, lead disconnection, and tricuspid valve dysfunction. While Micra has the advantage of not being associated with the aforementioned complications, there have been reports of cardiac injury during Micra implantation, which have raised safety concerns. Many reports have evaluated Micra safety, but its effect on cardiac function remains unclear...

BACKGROUND: His-Bundle pacing (HBP) is an emerging technique for physiological pacing. However, its effects on right ventricle (RV) performance are still unknown. METHODS: We enrolled consecutive patients with an indication for pacemaker (PM) implantation to compare HBP versus RV pacing (RVP) effects on RV performance. Patients were evaluated before implantation and after 6 months by a transthoracic echocardiogram. RESULTS: A total of 84 patients (age 75...

Background: Leadless pacemaker (LP) therapy has been proved effective in cases where traditional transvenous right pacing (TRP) failed. TRP through a bioprosthetic tricuspid valve (BTV) has always been considered an unpreferable solution because of possible deleterious effect of permanent pacing leads on BTV function and specifically on tricuspid regurgitation (TR). Very limited data exist about the feasibility and safety of LP implantation in this setting. Methods: We describe two cases of LP implantation through BTV in patients with failure of epicardial pacemaker implanted after cardiac surgery...

OBJECTIVE: Tricuspid annular size reduction with annuloplasty rings represents the foundation of surgical repair of functional tricuspid regurgitation. However, the precise effect of annular size reduction on leaflet motion and geometry remains unknown. METHODS: Ten sheep underwent surgical implantation of a pacemaker with an epicardial lead and were paced 200-240 beats/min to achieve biventricular dysfunction and functional tricuspid regurgitation. Subsequently, sonomicrometry crystals were implanted on the right ventricle, the tricuspid annulus, and on the belly of anterior, posterior, and septal tricuspid leaflets...

BACKGROUND: Complete heart blocks underwent to permanent pacemaker placement are a common complication of tricuspid valve replacement (TVR). If indicated, endocardial placement of a right ventricular (RV) lead is precluded in the presence of mechanical TVR. CASE PRESENTATION: A 20-year-old female patient firstly underwent metallic prosthetic valve operation with tricuspid valve endocarditis in 2014. Three years after the operation, echocardiography revealed dysfunction of the prosthetic valve thus reoperation was decided...

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...
