Filter by:Coronary artery narrowings interfere with blood flow to the heart which can cause chest pain and heart attacks. Cardiologists can treat these narrowings with balloons and stents. However, some narrowings can become very calcified and hard making treatment with balloons and stents difficult. Rotational atherectomy is a tool to treat calcific coronary disease. It uses an ablative drill to break down the hardened plaques inside the coronary arteries facilitating subsequent treatment with balloons and stents. However, during this procedure patients can experience a slow heart rate which may compromise procedural safety. Cardiologists may use a temporary pacemaker that is inserted by separately accessing the heart through a large vein usually from the leg. This maintains a safe heart rate throughout the procedure. However, inserting the temporary pacemaker is associated with additional complications. We have developed and propose an alternative strategy to provide a temporary safety pacemaker during rotational atherectomy without the need for inserting an additional pacemaker.
Study of the ventricular activation patterns during left bundle area pacing and compare it with baseline activation during normal sinus rhythm in patients with and without baseline bundle branch conduction disorder.
Temporary cardiac pacing with active-fixation leads (TPAFL) using a reusable permanent pacemaker generator has been shown to be safer than lead systems without fixation. However, TPAFL requires the off-label (non-certificated) use of Pacemaker leads and generators. It is designed a fastening system to ensure the safety and efficacy of the procedure: the KronoSafe System®. The aim of this study is to demonstrate the safety and effectiveness of the KronoSafe System® for temporary pacing in a series of patients receiving TPAFL.
The purpose of this coverage with evidence development (CED) study is to evaluate complications and long-term health outcomes of the single-chamber Aveir Single-Chamber Leadless Pacemaker device (Aveir VR LP).
The aim of this proposal is to characterize the acute effect of early postnatal sound exposure on neuronal maturation of the respiratory control regions of the brain in preterm infants.
The purpose of the clinical investigation is to document the safety and the performances of the remote monitoring functions of the ALIZEA, BOREA and CELEA pacemakers, i.e. the RAAT, the RVAT and the remote alerts.
This is a prospective, non-interventional cohort study. It tests the hypothesis that - Pacemaker-derived monitoring of sleep-related breathing disorders and/or daily physical activity predicts clinical outcome. - Autonomic imbalance defined by an increased periodic repolarisation dynamics (PRD) predicts clinical outcome in pacemaker patients. - Autonomic imbalance defined by an increased periodic repolarisation dynamics (PRD) predicts the occurrence of AHRE in SR patients implanted with a DDDR pacemaker.
The study is designed to collect data on Cardiovascular Implantable Electronic Device (CIED) information, implant procedure details, and/or patient characteristics to support development of future CIED products and procedures.
At present, cardiac pacing has been widely used in the treatment of bradyarrhythmias and heart failure, which can effectively improve the survival rate of patients. With the rapid development of technology, different sites can be chosen to pace, such as right atrial appendage, the atrial septum and the right atrial wall in the atrium, His bundle, left bundle branch area, right ventricular apex, outflow tract, and left ventricular pacing via coronary vein in the ventricle. There are few studies comparing the long-term efficacy and safety of different pacing sites in daily practice. This study aims to observe the efficacy and safety of cardiac pacing at different sites in short and long term, and to compare the advantages and disadvantages of pacing at different sites.
CIED implants require different amounts of fluoroscopy; using 3-D mapping systems, these times could be reduced to near zero fluoroscopy. The investigators aim to describe to what extent fluoroscopy times are reduced on a routine basis on CIED implants
