OBJECTIVE: It has been a widely accepted practice that a previous placed pacemaker, automatic implantable cardioverter defibrillators, or central line can be a contraindication to placing a hemodialysis catheter in the ipsilateral jugular vein. Fear of dislodging pacing wires, tunneling close to the battery site or causing venous obstruction has been a concern for surgeons and interventionalists alike. We suggest that this phobia may be unfounded. METHODS: A retrospective review was conducted of patients in whom hemodialysis catheters were placed over a period of 10 years...

Leadless cardiac pacemaker (LCP) therapy has been established clinically as a feasible and safe alternative to conventional transvenous pacemaker therapy for patients with an indication for single-chamber right-ventricular pacing.1-3 However, reports on loss of telemetry and pacing output due to abrupt battery failure called the safety of one of the two commercially available systems seriously into question. The initial battery advisory with the Nanostim™ LCP was issued by the manufacturer in October 2016, who instantly called a global stop to Nanostim™ implants...

OBJECTIVE: In patients indicated for cardiac resynchronisation therapy (CRT), the choice between a CRT-pacemaker (CRT-P) versus defibrillator (CRT-D) remains controversial and indications in this setting have not been well delineated. Apart from inappropriate therapies, which are inherent to the presence of a defibrillator, whether adding defibrillator to CRT in the primary prevention setting impacts risk of other acute and late device-related complications has not been well studied and may bear relevance for device selection...

OBJECTIVES: This study aimed to assess the impact of pacemaker mode programming on clinical outcomes in patients with high-degree atrioventricular conduction disturbance (AVCD) after transcatheter aortic valve implantation (TAVI). BACKGROUND: Although high-degree AVCD after TAVI can receive pacemaker, recovery of the AVCD is often observed. Specific pacemaker algorithms (AAI-DDD mode switch) are available which favor spontaneous atrioventricular conduction. METHODS: Of 1,621 consecutive multi-center TAVI patients, 269 (16...

BACKGROUND: Fluoroscopic criteria have been described for the documentation of septal right ventricular (RV) lead positioning, but their accuracy remains questioned. METHODS AND RESULTS: Consecutive patients undergoing pacemaker or defibrillator implantation were prospectively included. RV lead was positioned using postero-anterior and left anterior oblique 40° incidences, and right anterior oblique 30° to rule out coronary sinus positioning when suspected. RV lead positioning using fluoroscopy was compared to true RV lead positioning as assessed by transthoracic echocardiography (TTE)...

BACKGROUND: This study sought to analyze in-hospital outcomes associated with pre-existing and newly implanted Permanent Pacemaker (PPM) in patients who underwent Transcatheter Aortic Valvular Replacement (TAVR). PPM implantation following the development of conduction abnormalities is a common adverse event following TAVR. Furthermore, PPM implantation rates are higher in TAVR patients compared to the surgical alternative, thus we have analyzed the predictors of pacing post-TAVR. METHODS: The study population was identified from the National Inpatient Sample Database between 2012 and 2014...

BACKGROUND: Damage to the cardiac conduction system requiring permanent pacemaker (PPM) implantation is a known adverse outcome of transcatheter aortic valve replacement (TAVR). A permanent-temporary pacemaker (PTPM) is a device that involves an active-fixation lead attached to an external pulse generator taped to the skin. We reviewed the utility of PTPMs as a temporary bridge measure after TAVR in patients with conduction abnormalities that do not meet conventional criteria for PPM placement...
