Filter by:Hypertrophic cardiomyopathy (HCM) is a heart disease characterized by hypertrophy of the left ventricular myocardium and is most often caused by mutations in sarcomere genes. The structural and functional abnormalities cannot be explained by flow-limiting coronary artery disease or loading conditions. The disease affects at least 0,2% of the population worldwide and is the most common cause of sudden cardiac death (SCD) in young people and competitive athletes due to fatal ventricular arrhythmia, but in most patients, however, HCM has a benign course. Therefore, it is of utmost importance to properly evaluate patients and identify those who would benefit from a cardioverter-defibrillator (ICD) implantation.
This study is a non-randomized, prospective study in patients with a diagnosis of epilepsy and previously implanted FDA approved Vagus Nerve Stimulation (VNS) devices. The goal of this clinical investigation is to evaluate the effects of adjusting vagus nerve stimulation parameters to engage cardioprotective effects.
A multicenter single arm open label evaluation of the ASSURE Wearable Cardioverter Defibrillator (WCD) defibrillation waveform in adult cardiac patients
S-ICD (subcutaneous implantable cardioverter-defibrillator) screening failure occurs in about 10% of cases. Predictors of screening failure are not yet well determined. Moreover, slight variations in electrode positioning may change vector configuration and therefore improve screening success rates
The purpose of this study is to determine whether the use of domperidone is associated with an increased risk of serious cardiac events among postpartum women in the six months following delivery. The hypothesis is that the use of domperidone will be associated with an increased risk of serious cardiac events among postpartum women. The investigators will carry out separate population-based cohort studies using health care databases in five Canadian provinces. Women with live births will be eligible to enter the cohort. We will identify all women who start domperidone during the six months following delivery and match them to similar women who do not start domperidone, with all included women followed until the occurrence of an adverse cardiac event or for up to six months after delivery. The results from the separate sites will be combined to provide an overall assessment of the risk of serious cardiac events in users of domperidone.
The study performed to demonstrate a reasonable assurance of safety and effectiveness of the Heart Guardian HR-501 when used in an out-of-hospital environment.
Sudden cardiac death (SCD) is one of the major causes of mortality in adults with congenital heart disease (ACHD). Risk stratification for sudden cardiac death in this patient group is challenging and at the current moment there are no clear guidelines on implantable cardioverter-defibrillator (ICD) implantation for primary prevention of SCD in this young patient population. The reason for this is the fact that this is a heterogenous group of patients and SCD is a relatively rare event. Because of this there have been no prospective studies on SCD in ACHD. However, multiple retrospective studies on ICD implantation in ACHD have shown that this treatment does appear to be effective. Researchers from the Academic Medical Center have identified several risk factors for sudden cardiac death. A risk score was created using this data, which has been validated in an internal and external cohort in a retrospective setting. The design of this study, including the conception of the risk score, its calculation method and validation will be published in an international scientific peer-reviewed journal. The hypothesis of this study is that the risk score accurately predicts the risk of sudden cardiac death.
Randomized controlled trial of acute use of electronic cigarette or tobacco cigarette on parameters of ventricular repolarization.
A prospective multicenter single arm open label study to evaluate ambulatory detection performance, arrhythmia detection and safety of the ASSURE™ Wearable Cardioverter Defibrillator (WCD).
In complete transposition of the great arteries (TGA) with previous atrial switch repair, and congenitally corrected transposition of the great arteries (ccTGA), the morphological right ventricle and its tricuspid valve continue to support the systemic circulation. This results in late complications including including sudden death. This retrospective multicentric study aims to evaluate the prevalence of SCD in a contemporary population of patients with a systemic RV and identify specific risk factors for SCD and hemodynamically significant ventricular arrhythmia This registry records demographics, clinical, imaging data, electrophysiological and laboratory of patients with a sRV and a transposition of the great arteries Primary end points are defined by sudden cardiac death, near-miss sudden death, as well as sustained VT requiring defibrillation.
