Filter by:The aim of this study is to identify existing definitions and therapeutic approaches for acute right ventricular injury (RVI) in patients receiving extracorporeal membrane oxygenation (ECMO) for respiratory support. The objective of the study is to generate expert consensus statements on the definition and management of acute RVI in this high-risk patient population, using a Delphi method. The standardised RVI definition during ECMO for respiratory support and a consensus-based management approach to RVI will facilitate systematic aggregation of data across clinical trials to harmonise patient selection and compare therapeutic interventions.
Right ventricular (RV) dysfunction is associated with increased morbidity and mortality in patients with chronic obstructive pulmonary disease (COPD). Assessment of RV function by echocardiography is challenging. Easy visualization of the right atrium (RA) by echocardiography , allows quantitative, highly reproducible assessment of RA volume. The aim of the present study is to evaluate the relationship between the right atrial volume index (RAVI) and functional capacity in patients with COPD , quantified by the COPD assessment test (CAT) questionnaire as an early predictor of right heart affection.
Right heart failure during cardiac surgery is associated with increased perioperative morbidity and mortality. In this context, it is imperative to develop simple diagnostic tools to detect right heart failure. The purpose of this observational study is to determine if ultrasound Doppler of the femoral vein can detect and predict right ventricular failure after cardiac surgeries requiring cardiopulmonary bypass. It is expected that an elevated pulsatility of the femoral vein before the induction of general anesthesia is associated with perioperative right heart failure.
RV dysfunction has been associated with increased mortality in the ICU and cardiac surgical patients. Thus, early identification of RV dysfunction at less severe stages will allow for earlier intervention and potentially better patient outcomes. However, so far, no studies have reported prospectively the prevalence of abnormal RV pressure waveform during cardiac surgery and in the ICU. Our primary hypothesis is that the prevalence of abnormal RV pressure waveform occurs in more than 50% of cardiac surgical patients throughout their hospitalization. Those patients with abnormal RV pressure waveform will be more prone to post-operative complications related to RV dysfunction and failure in the OR and ICU.
The purpose of this study is to determine the utility of tricuspid valve repair at the time of LVAD implantation for patients presenting with moderate or severe tricuspid regurgitation. The study will be a randomized trial for patients presenting for LVAD implantation to either tricuspid valve repair or no tricuspid valve repair. The data will be analyzed as both an intention to treat analysis as well as an "as treated" analysis with the primary outcome being rates of right ventricular dysfunction post LVAD implantation. Tricuspid valve repair for these patient is currently being done for some patients, without any strong data to either support such practice or negate it.
Portal flow pulsatility detected by Doppler ultrasound is an echographic marker of cardiogenic portal hypertension from right ventricular failure and is associated with adverse outcomes based on previous studies performed at the Montreal Heart Institute. This multicenter prospective cohort study aims to determine if portal flow pulsatility after cardiopulmonary bypass separation is associated with a longer requirement of life support after cardiac surgery.
This is a Phase 2, single-center, randomized placebo controlled trial of famotidine (an H2 receptor antagonist) in adults with pulmonary arterial hypertension. The study will evaluate the safety and clinical efficacy of a 24-week course of famotidine.
The PREPARE-MVR (PRediction of Early PostoperAtive Right vEntricular failure in Mitral Valve Replacement/Repair patients) Study aims to evaluate those preoperative factors which can predict the early postoperative right ventricular failure or determine the functional shift seen in right ventricular function after mitral valve replacement/repair. The PREPARE-MVR study focuses mainly on echocardiographic (both conventional and advanced) parameters and includes right heart catheterization intraoperatively and in the early postoperative period as gold standard method.
This is a Phase 1b/IIa, single centre, non-randomised open-label uncontrolled study to assess safety, effect and PK of oral CRD-102 in patients with RHF associated with the presence of an LVAD.
The investigators research the early improvement of fluid retention and mid-term prognosis through the administration of tolvaptan for the patient with tricuspid regurgitation and right heart failure after left heart valves replacement.
