SONIC-PE is a multicenter, prospective, single-arm study of 10 patients with bilateral PE treated with ultrasound-facilitated, catheter-directed lower-dose fibrinolysis (total dose 8 mg tPA given as 2 mg/hour/catheter over 2 hours) followed by 50 patients (total dose 6 mg tPA given as 3 mg/hour/catheter given over 1 hour) with the EKOS+™ system to determine its impact on the change in RV-to-LV diameter, refined Modified Miller Score, and distal pulmonary vascular blood volume as well as to assess International Society on Thrombosis and Haemostasis (ISTH) major bleeding.
The reliability of advanced echocardiographic and cardiac magnetic resonance (CMR) parameters at repeated measurements is not fully clarified. Test-retest reliability of measurements is crucial for follow-up studies and for clinical monitoring of patients to detect a significant change in ventricular performance, as well as to assess the outcome of various therapies on the size and function of cardiac structures. For echocardiography, the variability of the measurement is more complex, as it depends both on acquisition and reading variability, but also closer to the real life setting than observer variability. Much more limited data exist on the test-retest reliability of right heart parameters, i.e. right ventricle (RV), right atrial (RA) and tricuspid annulus (TA) parameters than on their observer variability and than of the equivalent left-sided parameters. The primary aim of the study is to compare the test-retest reproducibility and agreement of advanced echocardiographic parameters of RV and RA size and function, and of tricuspid annulus (TA) size against the respective parameters obtained by conventional echocardiography and by CMR (where applicable).
This study will test the feasibility and effectiveness of an innovative model of care for cognitively impaired patients with heart failure. This program aims to improve cognition, reduce dementia risk and cardiovascular events, and will be supported by innovative digital technology for wide scale rollout and implementation. Findings from this research will transform the way healthcare is delivered to cognitively impaired patients with heart disease who have a very high risk of developing dementia.
The goal of this multi center observational prospective study is to analyze the concordance between the signs and symptoms of RHF and echocardiographic features of RVD in patient with heart failure. The main questions it aims to answer are: 1. to assess the incidence of RVH and RVD in each HF subtypes. 2. to evaluate prognostic impact ( in terms of cardiovascular mortality and HF hospitalization) of different RVD patterns during a mean followup period of 3 years 3. To investigate the incidence of different RV maladaptation ( isolated RV dilatation, isolated Pulmonary hypertension, combined pattern) in each HF groups and the related outcome. Participants will follow by direct check up visit and/or virtual visits every 6 months for a mean follow-up period of 3 years.
Evaluation of cardiac biomarkers and the left and right ventricular systolic and diastolic function in asthmatic children in Assuit university hospital
To assess prevalence of right ventricle dysfunction in critically ill patient. To assess impact of RV dysfunction on short term (ICU stay, hospital stay, or mortality ≤30 days) and long term outcome (>30 days). To assess the accuracy of different parameters of RV dysfunction.
The study aims to compare permanent Conduction System Pacing (CSP) with the standard therapy - Right Ventricular Pacing (RVP) or Biventricular Pacing (BVP) - in preventing the development and progression of symptomatic Chronic Heart Failure (CHF) and improving survival in patients after Transcatheter Aortic Valve Implantation (TAVI).
A study to see how common right heart failure (right ventricular dysfunction) after major surgery is, and to investigate if right ventricular dysfunction causes worse patient outcomes after surgery.
The main objective of the study is to demonstrate that prophylactic treatment of patients with asymptomatic frequent (>10%) PVCs is superior to simple follow-up strategy with no therapy to prevent subsequent LV dysfunction at 24 months. The prophylactic treatment is based on drugs ± ablation (ablation can be performed if the PVC burden remain >10% after 2 lines of AAD treatment since the initiation of the study). The primary endpoint will be the development of LV dysfunction (PVC-iCMP) defined as a 15% relative LVEF decrease (and/or a LVEF <50%) within 2 years following randomization, on cardiac magnetic resonance imaging (cMRI) (or transthoracic echocardiography (TTE) when not possible).
