Filter by:The purpose of this study is to evaluate the device performance and monitor the safety and effectiveness of the Berlin Heart EXCOR Active Driving System while being used with the approved EXCOR Pediatric Ventricular Assist Device. EXCOR Active Driving System is intended for use with the approved EXCOR Pediatric VAD. The EXCOR Pediatric VAD is intended to provide mechanical circulatory support as a bridge to cardiac transplantation for pediatric patients. Pediatric candidates with severe isolated left ventricular or biventricular dysfunction who are candidates for cardiac transplant and require circulatory support may be treated using the EXCOR Pediatric. EXCOR Active is intended for use in a clinical setting. EXCOR Active can be used in any kind of hospital unit (e.g. OR, ICU, intermediate care unit or general care unit). The driving unit may be moved between clinical units using the caddy or baby buggy; however, a patient must always be accompanied by a person trained in the use of the manual pump and emergency procedures during transport in the event of an emergency. The driving unit can be transported during operation.
Patient reported outcomes are becoming increasingly recognized as an important metric to determine efficacy of interventions following recovery after cardiac surgery. Quality of Recovery 15 survey is a tool that attempts to measure patients' recovery across several different domains (i.e physical, emotional and social). This tool has been validated extensively in the post operative patient population, but these studies contained only small numbers of cardiac surgery patients. This population faces unique challenges to recovery such as a longer duration of mechanical ventilation, ICU and hospital LOS, delirium, significant pain in the first 24-48 hours and post operative arrhythmias. This study aims to validate the QoR 15 in this population exclusively to determine if it is feasible, valid, reliable and responsive in this unique population.
Comparison of prenatal and postnatal cardiac function assessed by echocardiography using pulsed wave Doppler, Tissue Doppler and speckle tracking (strain and strain rate) between foetuses/neonates with a structural heart disease, with an fetal growth restriction (FGR) and healthy fetuses/neonates.
The study aims to compare a preventive percutaneous coronary intervention (PCI) plus optimal medical treatment (OMT) strategy vs. OMT for treatment of non-functionally significant non-culprit lesions presenting with optical coherence tomography (OCT) findings indicative of vulnerable plaque, in patients with ST-elevation myocardial infarction (STEMI) and multivessel disease.
Heart failure is a major cause of death and hospitalization in Canada. Many of the symptoms experienced by patients with heart failure relate to having fluid accumulate in the lungs causing difficulty breathing, swelling in the legs, and an increase in weight. Thus, one of the cornerstones of managing heart failure includes the use of medications known as diuretics that target the kidneys to reduce fluid accumulation via urination. Deciding on the correct dose of this medication can be quite nuanced as under-dosing can lead to accumulation of fluid, and over-dosing can dehydrate patients and potentially result in lightheadedness/fainting and damage to the kidneys. Currently, options for prescribing diuretics for heart failure include 1) giving patients a regular, fixed dose or 2) having patients monitor their daily weight as a surrogate of their fluid status and then take a dose of diuretic based on a pre-prepared scale. The rationale behind the flexible weight-based diuretic scale is that it can potentially detect early fluid accumulation and thus possibly prevent hospitalization or ED visits, and it also avoids over-dosing and potentially dehydrating patients. Currently, it is not clear whether the flexible diuretic regimen is better than the fixed-dose regimen in preventing ED visits, hospitalizations, kidney damage, or death and as such, this pilot study will directly compare the two commonly used regimens in the management of chronic heart failure patients.
Data regarding the safety and efficacy of ivabradine use in severely decompensated HFrEF requiring inotropic support is limited to case series.1 This study aimed to evaluate ivabradine safety and tolerability in admitted cardiogenic shock patients who started on dobutamine infusion for inotropic support.
Investigators will determine whether N-of-1 trials, as a pragmatic, patient-centered approach to medication optimization that can overcome key barriers of deprescribing, can lead to increased subject confidence regarding the decision to continue or discontinue beta-blockers in older adults with Heart Failure with Preserved Ejection Fraction (HFpEF).
In this trial we intend to evaluate the safety and effectiveness of the INSPIRIS valve prothesis in the pulmonary position in patients of five years or older, with congenital or acquired pulmonary valve disease, requiring replacement of their native or prosthetic pulmonary valve.
This study seeks to investigate the clinical value of novel echocardiographic indices, including myocardial work parameters, during the acute phase of heart failure hospitalization. The trajectory of novel echocardiographic indices from the start to the end of hospitalization will be captured, as a means to unravel and subsequently better understand the diverse pathophysiology of different phenotypes of the heart failure continuum. Correlation between novel echocardiographic indices with clinical data, biochemical data, different heart failure phenotypes, and therapeutic maneuvers will be attempted. Prognostic implications of those indices will be explored.
Depression is a known risk factor for cardiovascular disease (CVD), and this comorbidity contributes significantly to the morbidity and mortality of women. The menopausal transition or perimenopause is a period of vulnerability for both depression and CVD, making it a key time to study this critical public health issue. This research will preliminarily explore whether disruption in two novel stress pathways 1) the renin-angiotensin-aldosterone system (RAAS) and autonomic nervous system (ANS) and their relationship may underlie the link between these illnesses. Findings will provide important insight into potential mechanisms by which depression during perimenopause may increase risk for CVD in midlife women, which will inform potential risk reduction and treatment strategies that can improve health outcomes in this population.
