Filter by:Durable left ventricular assist devices (dLVAD) have been increasingly utilized since the mid to late 1990s, with an uptick of utility starting in 2010 following expanded indications for therapy to not only include a bridge to transplantation strategy, but also for those individuals who suffer from advanced heart failure (HF) and do not qualify for cardiac transplantation. Despite the decreasing size of the newest generation devices leading to a lessened occurrence of adverse events, bleeding and infection still remain a concern for clinicians, as well as a general lack of predictability towards adverse events in individuals with a dLVAD in place. There is a lack of description in the literature currently, regarding the interface between what the pump data provides and what is seen in clinical practice. There also is little known about the effects of what is provided in the pump data, in correlation to quality-of-life following dLVAD implantation. Therefore, the purpose of this study is to prospectively analyze normal and abnormal pump data through pump operations such as suction events, low flow alarms as well as other adventitious alarms, PI events and power cable disconnects greater than 20 seconds, from the HeartMate 3 ® dLVAD in order to clinically correlate this data to quality of life, frailty and other various medical conditions and adverse events as defined by the Interagency Registry for Mechanically Assisted Circulatory Support (Intermacs). This will be achieved through two aims: 1) Evaluate the effectiveness of dLVAD pump operations data on clinical practice application (quality of life, frailty and various medical conditions, and adverse events such as GIB, RHF, infection, hypertension, arrhythmias and stroke); and 2) Evaluate correlations and relationships of longitudinal normal and abnormal dLVAD pump operations data, to demographic and clinical variables. This study is the first study to evaluate HeartMate 3 ® dLVAD pump operations data over time for effectiveness in the clinical practice.
The aim of this study is to investigate the association between hypoglycemia, glycemic variability and cardiac arrhythmias in patients with diabetes Type II (T2D) already implanted with implantable cardiac defibrillator (ICD) and monitored remotely through Bluetooth technology and CGM (continuous glucose monitoring).
The primary objective of the study is the development of a mathematical model for predicting potassium kinetics during and after the dialytic session. The secondary objectives of the study are: 1. the definition of a correlation between the kinetics of intra and extra-cellular concentrations of potassium during and after the dialytic session and the onset of arrhythmias; 2. the use of the mathematical model to modify the blood concentration of potassium by acting on the composition of the dialysis bath in order to minimize the risk of onset of arrhythmias during and after dialysis.
This study aims to compare the antiarrhythmic and cardioprotective effects of Atorvastatin versus Magnesium Sulfate after Cardiac valve Replacement Surgery
The growing use and the expanding indications for cardiovascular implantable electronic devices (CIEDs) have been associated to an increase of device removal. The indications of CIEDs removal are infectious (55%) or noninfectious (45%) such as upgrading of devices, nonfunctional devices and thrombosis. Removal can be performed according to transvenous or surgical procedures. Transvenous lead removal (TLR) must be done by experimented cardiologists and respecting current consensus. TLR can be done with conventional techniques involving inserting locking stylets and telescoping sheaths around the pacing leads to separate them from the surrounding scar tissue. These conventional procedures have a success rate of ≈65%. TLR thanks to laser sheath has been validated and improved the success rate until >95%. However, the TLR from chronically implanted CIEDs still carries a significant risk of procedural failure, morbidity, and mortality, related to tearing of the great vessels and cardiac structures, even when performed by experienced operators. Even if the transvenous extraction using laser sheath seems to be more effective, this strategy would be more expensive. Considering the availability of several strategies for TLR and the cost heterogeneity of procedures, a cost assessment in real life of these therapeutic strategies is essential for an optimal choice of therapeutic strategies.
The objective is to demonstrate feasibility of new 'Magnetic Primary' catheter tracking algorithms within the Velocity Research Platform (VRP) by assessing the frequency of shift/drift during ablation compared to the current commercial EnSite Precision 2.0.1 The secondary objective is to evaluate catheter rendering in the VRP system.
Background: Arrhythmia recognition is a fundamental skill for the provider of advanced life support (ALS). Acquire it is difficult, leading to the birth of systematic methods in an attempt to simplify and optimize, however, it has not compared the effectiveness among the three methods with more evidence among professionals with varying degrees of medical training (ALS Workshop participants). Objective: To determine and compare the effectiveness of the three most widespread and with more evidence systematic methods (10, 6 and 4 steps) for the recognition of arrhythmias in a short-term and its perceived easiness among ALS workshop participants. Methods / design: Educational Cuasi experimental trial with pre and post intervention measurement, blind, with randomized allocation, in 84 ALS workshop participants. Three systematic methods to recognize arrhythmias will be taught and their effectiveness to diagnose in a short-term and its perceived easiness will be measured and compared.
People that have survived, or are at high risk of a lifethreatening ventricular arrhythmia are routinely offered a defibrillator (ICD). An ICD is an implanted device which can recognise a ventricular arrhythmia and then try to treat it, either by rapidly pacing the heart or by shocking the heart. Currently, very fast ventricular arrhythmias, known as VF, can only be treated with a shock. Patients find shocks painful and this study is intended to find out whether it is possible to pace the heart at very high rates during VF. It is hoped that if this is possible, further research could lead to effective treatment of VF with pacing rather than shocks, and therefore better outcomes for patients.
The purpose of this study is to determine the safety on sauna followed by cold water bath, a common practice in many countries, 30 healthy subjects aged 40 years and older will be at the Montreal Heart Institute Prevention and Cardiac Rehabilitation centre.
The aim of this study is to determine if anti-arrhythmic drugs with a sodium channel-blocking mechanism exert a detrimental electromechanical effect on cardiac function in patients depending upon baseline intraventricular conduction and left ventricular function.
